“What’s wrong with my goldfish?!” you ask in a panic. “It looks sick!”
Could be.
But before we go on, you should know this up front:
If your goldfish isn’t well, there is a big chance that it actually doesn’t have a disease.
Most goldfish who LOOK sick are really living in bad tank conditions. (The symptoms are often the same!)
The water may look clean, but it is actually filled with deadly poisons.
Some of these come in through the water you filled the tank with, some are actually made by the fish themselves as they respire and *eherm* go to the bathroom.
Ammonia and nitrite are two major culprits in causing sick fish. Even low amounts will cause irritation, stress and lethargy. But a low pH will cause many other issues because goldfish need the pH to be around 7.4.
Don’t miss this:
Symptoms of water poisoning in goldfish are the exact same as symptoms of other diseases.
So how do you know what’s going on?
There’s a very important step every fish owner needs to take when confronting a problem:
TEST THE WATER.
A liquid water testing kit is something every fish keeper needs on hand at all times, especially for emergencies. Think of it as a necessary investment you need to make in order to be a good, responsible goldfish owner. 😉
Before you assume your fish needs meds, please test the water or you can end up killing your fish.
So without further ado, here is my complete list of common – and some not-so-common – goldfish diseases, that are actually diseases:
Parasitic Goldfish Diseases
1. Ich: Did it Snow on Your Goldfish?!
Ich (pronounced “ick”) is a parasite also called “white spot disease.”
The white spots of ich are actually not the parasite itself, but the skin of the goldfish stretching over the parasite.
Outbreaks are very common with new fish that have been stressed, weakened, kept in poor conditions or not quarantined (usually all of the above).
If left untreated, it will kill your fish.
Symptoms:
- Clamped (flattened down) fins.
- Darting and scratching against on objects in the tank, aka “flashing.”
- White spots that look like salt granules covering the fish from nose to tail.
Sometimes you might see irritation, lethargy and breathing hard.
If your goldfish has these symptoms, it sounds like you have a case of ich on your hands.
But you should know:
Not all goldfish who do have ich show the classic white speckles. They may just have the behavioral symptoms.
… And not all fish with white spots have ich.
You might see white spots in the wen of an Oranda that aren’t disease-related at all.
Treatment & Prevention:
Fortunately, the cure for ich is pretty straightforward.
It involves:
- Raise the temperature up to 80 degrees (F). This will speed up the ich’s life cycle.
- Salt the tank. You will need 3 teaspoons of aquarium salt for every gallon (a .3% solution), dissolved in a cup of tank water.
- Wait for 7 to 10 days and keep the water pristine. If you do a water change, replace the amount of salt you took out.
If your fish have come down with ich, it’s a sign that something’s probably not right with your tank. It may be a good idea to take a look at your water change schedule or how many fish you have in the tank.
Want to prevent it in the future?
Keep stress low on your fish by providing them with clean water and enough space.
If you have more than one tank, don’t share equipment such as nets or siphons because ich can live out of water (yikes!). This is just asking for trouble.
And ALWAYS quarantine any new fish you get before introducing them to the others.
2. Flukes: The Invisible Blood-Sucker
Flukes are one of the most common parasites found on goldfish.
In fact, if you have bought a goldfish from the pet store, it is safe to assume it has Flukes – both body Flukes and gill Flukes.
How do they hurt your fish?
They clamp on tight to the skin with spiky hooks and feed on the slime coat, causing the goldfish to constantly bleed until it dies.
And the scary thing about these bad bugs is that you can’t see them! (Without a microscope, that is.)
But it gets worse:
By biting the goldfish, they can inject bacteria into your fish that cause other problems, such as ulcers.
Now, how can you might be dealing with Flukes?
Symptoms:
While it takes a microscope to know 100% that your fish has Flukes, you can spot their symptoms. In fact, it is safe to assume that most fish from a pet store are carrying them – they are THAT common.
- Goldfish harboring body Flukes will twitch their fins and rub, sometimes bashing themselves on the walls and floors of the tank in an effort to scratch.
- Eventually shed their slime coat, trying to rid themselves of the pests.
- They don’t want to be around the other fish and clamp their fins.
- Sometimes they may get very thin.
- Usually fish with body flukes have gill flukes, too.
- Gill Flukes causes them to have trouble breathing so they gulp at the surface.
Treatment & Prevention:
Here’s the kicker:
While you can treat the tank with salt and kill some major parasites, there will always be one left behind: the Fluke.
They are salt resistant. Great, right?
So, this means that you are going to have to bring out the big guns and buy your fish some special anti-parasite medication.
I don’t recommend ever using chemical-based medications like Praziquantel or Formalin because they are very dangerous to your aquarium environment and the fish that live in it.
Instead, I treat my new fish that have flukes with MinnFinn.
In the future:
Please don’t wait until your fish are showing signs of a Fluke infestation to treat.
All new fish must be treated for Flukes (unless they have been treated for you by a breeder).
If you don’t want your fish to come down with Flukes, never introduce new fish into their tanks without treating them first.
Always, ALWAYS quarantine.

3. Anchor Worm: Hooked On Your Goldfish
Anchor Worm is a goldfish disease that comes up when the seasons change, usually in the fall.
Because it is so contagious, an entire tank can quickly get infected.
The fish don’t even have to be stressed out to get them.
By the time you actually see the worm, a lot of damage has already been done to the fish.
In many cases, the goldfish have already died or it is too late to reverse the damage done to the remaining fish.
That’s why it’s important to diagnose early.
Especially because place where the worm was stuck on can get infected and kill the fish if it isn’t cleaned.
Symptoms:
The first symptoms are flashing (itching) and scratching.
Then all doubt goes away when the goldfish gets a nasty, stick-looking worm poking out of it.
Where the worm is attached may become very red and bloody.
If your fish has Anchor Worm, you will want to stop it in its tracks. How?
Treatment & Prevention:
What you will need to do is remove any worms you can see with tweezers.
Then use hydrogen peroxide to clean the wound. This will help prevent infection.
This is important:
Salt won’t get rid of anchor worm.
Neither will most of the common fish medications on the market.
Only Cyromazine is an effective anti-anchor worm medicine accessible to us fishkeepers.
You will need to treat the whole tank, not just the fish you see the worms on.
Check out our article on goldfish anchor worm treatment.
As far as prevention goes, be sure you don’t add new fish or plants without quarantining them first so they won’t spread disease.
4. Fish Lice: “Flying Saucer” Bugs
The fish louse is more common in ponds than in indoor aquariums. They may be seen in your tank if the fish has been brought in from outside.
It is actually a crustacean-type parasite that lives by sucking blood (ew!).
They spread like crazy, too.
Symptoms:
Fish lice are visible little green specks shaped like discs that can be seen hopping around your fish. Usually they show up on stomach, chin and around the fins.
The fish may scratch and itch themselves, leaping and darting around in irritation.
Here’s something else:
When the case gets really bad, you might see red wounds on the body.
Treatment & Prevention:
Fish lice is resistant to many treatments.
For this pesky parasite, salt won’t work. It’s a lot like anchor worm in that it responds to Cyromazine.
If you don’t want to have lice in your tank, be sure to quarantine all of your newcomers and treat them for parasites ahead of time.
Read the full goldfish lice treatment guide.
5. Velvet: It Doesn’t Feel Soft!
This parasite is also called “Gold Dust.”
Fortunately, it’s pretty rare in goldfish.
It sticks onto the fish by a long needle, causing irritation and other symptoms.
Symptoms:
A goldfish with velvet appears to be sprinkled with a fine yellow powder.
This gives the fish a “velvety” appearance.
Your goldfish might also start shedding lots of slime to get rid of the parasite…
…or scratching on things to dislodge them.
Other symptoms may include weight loss or clamped fins.
Treatment & Prevention:
It’s too bad that salt doesn’t do much to fight Velvet.
That’s why you might have to go for something stronger, like Copper.
The Velvet parasite uses light to live.
So you might also try covering the tank with black paper or cloth to block out the light for a while.
Chances are you probably won’t ever encounter Velvet. But if you want to stay on the safe side, always quarantine any new fish.
6. Trichondia: Hobos in Your Goldfish Tank?
These little guys don’t actually feed on your goldfish.
Instead, they use your fish as a taxi and hotel service combined.
But the parasite stresses your fish, so you don’t want it around.
They are more common in dirty tanks.
In fact, a clean tank sometimes gets rid of them completely without treatment!
Symptoms:
Scratching, (also called “flashing”) and irritation is a symptom of Trichondia.
Over time, the fish may get ulcers from so much itching.
They may stop eating as well.
Treatment & Prevention:
You can treat Trichondia with a high concentration of salt, anywhere from 0.3% (which is 3 teaspoons per 10 gallons) to 0.9% (3 tablespoons per 10 gallons).
However, this high of a concentration is extremely stressful to goldfish. In an effort to kill the parasite, you could kill your fish.
Again, MinnFinn can be useful in a case like this.
Preventing this parasite is done through quarantining new fish.
7. Hole-in-the-Head: Who Needs That?!
With a name like that, you know it’s bad.
Most of the time it is an ulcer-causing bacteria and parasite combo attacking the fish during a time of weakness.
Goldfish that have wens (such as an Oranda or Lionhead) may be more prone to this infection.
What’s so dangerous about it?
The bacteria can spread from the outside of the fish to the inside.
Then an internal organ gets destroyed…
… and the fish dies.
Symptoms:
This disease often starts out as a little red dot or bloody patch on the head, usually above the eyes.
Over time, the area starts to sink in deeper, pitting and spreading to cause multiple holes.
Treatment & Prevention:
A word of advice:
If your fish has Hole-in-the-Head, chances are that the water is messed up. Bad.
You can do everything you can think of to treat Hole-in-the-Head, but if your goldfish’s environment isn’t right…
… NOTHING you do will help.
It won’t work. Your fish will only continue to go downhill.
Perfect water conditions are absolutely necessary for your fish to heal.
As far as treatment goes:
Swab the hole with Hydrogen Peroxide once.
The antibiotics Furan 2 and Kanaplex used together can knock this out.
Because Hexamita parasites are at play, you also need to treat with Metroplex.
Preventing Hole-in-the-Head much easier than treating it.
Don’t overcrowd your fish.
Do your water changes regularly.
Keep their homes clean and pristine.
8. Fin Rot: The Fin-Eating Disease
A bacteria infection called fin rot is another common goldfish disease.
Like ich, it shows up when the fish is stressed or living in bad water.
But unlike ich, it can be very stubborn and usually takes weeks to get rid of completely.
If you let it go untreated too long, the fish’s fins may never grow back.
How do you know if your fish has fin rot?
Symptoms:
Fin rot starts out as a cloudiness on the fins.
It doesn’t take long before the fins get whiter at the tips and begin to rot away, sometimes splitting.
Eventually the fins can erode to the base of the tail.
By that time, they are PERMANENTLY ruined.
That’s why you want to start treatment as soon as you know it’s fin rot.
Treatment & Prevention:
So your fish has fin rot? Don’t panic – all may not be lost.
If you get to it in time, the damage can be reversed and the fins might heal back.
One danger in treating fin rot is accidentally burning your fish with medications, making the problem even worse.
That’s why I don’t recommend them.
There are a couple other options when it comes to treatment.
A hydrogen peroxide swab offers a much safer route than medications. Dab the affected areas on the fins with a Q-tip dipped in the peroxide every 24 hours.
Or MinnFinn can stop the rot in its tracks.
Really advanced cases might require antibiotics like Sulfaplex to save the fish.
If all goes well, you will start to see black on the rotted areas instead of white. This is a sign of healing.
Preventing fin rot is much easier than treating it. That’s why you should do all you can to avoid running into water quality issues, which are a major cause of this.
9. Mouth Rot: Wait, A Fish Has Gotta Eat!
It could be caused by parasites or bacteria, but in either case mouth rot is a bad deal.
In its later stages, the fish won’t be able to eat, making early detection vital.
Usually the tank is overcrowded, and almost always the water is bad.
Symptoms:
Initially, you might notice your goldfish rubbing its mouth on the sides of the tank or decorations in the aquarium.
Then the mouth begins to get red. VERY red.
Eventually the area starts eroding…
… until the lips come off…
… and the mouth caves in on itself…
… leaving only a jagged hole.
Pretty nasty, right?
That’s why you don’t want to let it get to that point, starting treatment as soon as possible.
Treatment & Prevention:
Assuming the water quality is perfect, you have some choices when it comes to treatment.
Hydrogen peroxide swabs and MinnFinn have been used with success.
For advanced keepers, antibiotic injections can prove helpful if it is a life-or-death situation.
You should know:
A goldfish with very progressed mouth rot often is left with permanent damage. Often times the fish is no longer able to eat and will starve to death. If your fish is in this situation, it may be best to consider putting your fish to sleep.
Now you know why it is WAY easier to try to prevent fin rot than treat it.
Great water quality and properly stocking your tank are the two most important things you can do to stop your fish from getting this nasty goldfish disease.
10. Ulcers: Ever Growing Holes
These are large red body sores that start off as a patch of red.
The bad news?
They can get large and deep very quickly.
The theory goes that ulcers are caused by flukes, which inject dangerous bacteria into the fish’s skin.
Beware!
If left untreated, the bacteria can spread from the skin into the organs.
Symptoms:
Ulcers usually start as an irritated-looking patch of red on the body.
Sometimes the scales may prickle around the area.
(Hint: now’s when you should start treating!)
They can also occur on the head of the fish, often on the ones who have wens.
Shortly, a bloody hole is visible. The hole continues to spread, perhaps bordered with pieces of hanging skin.
Other fish may start nibbling at the wound, making it worse.
Treatment & Prevention
Because ulcers are bacterial in nature, they need to be treated as such.
Ulcers can kill quickly by many means…
… so the sooner you treat, the better.
How?
In mild cases, this approach can work:
- Change the water. Your fish won’t recover in less than perfect conditions.
- Scrub the ulcer with hydrogen peroxide on a cotton ball.
- Treat with MinnFinn following the instructions on the bottle.
You should know:
It will probably take some time to improve.
Not worse might actually be better, as weird as that sounds.
Overreacting can stress out or even kill your fish, so don’t start doing shotgun treatments out of panic. Stick to the plan.
A healing ulcer may look darker initially, then get lighter each day.
To prevent ulcers, some methods are to be sure to treat for flukes (if you bought a pet store fish) and always, ALWAYS keep the water perfect.
Bad ulcers require a different approach to treatment that I talk about in further detail in my book.
11. Pop Eye: NOT the Sailor Man
Some goldfish have eyes that naturally protrude.
Others are actually sick and need help.
A gross problem some goldfish run into is Pop Eye.
It is more of a signal that something is wrong than a disease itself.
Pop Eye often means there is serious bacterial infection inside the fish.
Symptoms:
You may first notice the eyes of the fish seem to protrude more than usual.
One or both eyes may be affected.
Sometimes very rapidly, they bulge outwards from the head, surrounded by “bags” of fluid.
During this phase, they may easily come off.
Pop Eye is often accompanied by dropsy or other bacterial infections.
Treatment & Prevention:
Adding Epsom salts at 1/4 tsp per 10 gallons can be a good idea. It can help to reduce the pressure behind the eyes.
To fight the infection, Kanaplex is recommended.
Of course, good water conditions are crucial for both treatment and prevention of Pop Eye.
12. Dropsy: The Pine Cone Disease
What is Dropsy?
Basically, Dropsy happens to a goldfish when there is too much fluid inside its body.
Like Pop Eye, it’s a symptom of an internal problem, not the problem itself.
Why is the fish have a problem with its fluids?
There are many possibilities.
If you are always having problems with Dropsy on a regular basis, bad water and/or an improper diet are almost always the main causes.
Bad water weakens the fish and makes it more likely to get a bacterial infection.
A bad diet ruins the internal organs that are in charge of the body’s fluids.
In some cases, parasites inside the fish may be an issue.
Other not-so-common causes include tumors, egg-binding and temperature shock.
Read more about Dropsy treatment here.
Symptoms:
Dropsy shows itself in two main ways:
- Extreme swelling in the belly, like a hot air balloon.
- Or scales standing out all over the body, like a pine cone.
You may also see Pop Eye present.
How do you treat Dropsy? Is there even a cure?
Treatment & Prevention:
I wish I had better news…
But by the time you can tell your fish has dropsy, 99% of the time… IT’S TOO LATE.
This is because there has been some kind of internal damage. And once the organs inside the fish have been destroyed, there is no turning back the clock.
A fish may last a few days to a few months before it dies.
For a fish that has Dropsy and Pop Eye, the case is always terminal.
Not good.
Because of the high mortality rate, it may be the kinder thing to opt for euthanasia rather than treatment.
What makes treating Dropsy so difficult is that many times you don’t know what caused it. Remember, it’s a symptom, not a disease.
Here is something you can try:
If a bacteria infection is causing the Dropsy, antibiotics may prove useful.
Epsom salts might help to ease the pressure from fluid buildup.
But treatment won’t help in less than perfect water.
So:
How can we avoid this horrible condition?
The best way to prevent Dropsy is by keeping the water quality good at all times, feed sparingly and don’t overstock, though dropsy has many different causes even outside of these.
13. Cloudy Eye: It’s Kinda Foggy in Here!
Also called White Eye, this condition is most found on goldfish that have protruding eyes.
This is because they are more prone to injury and then infection by sneaky bacteria. The injury that causes Cloudy Eye could also be a burn from ammonia.
Symptoms:
Just like it sounds, this disease makes the normally clear lens of a goldfish’s eye hazy or foggy-looking.
The fish may find it harder to see.
Cloudy Eye can be found alongside other symptoms, too.
Treatment & Prevention
With a little fish-safe salt (3 teaspoons per gallon), perfect water conditions and time, Cloudy Eye should clear up quickly.
To avoid it in the first place, don’t use decorations with sharp edges and keep the water conditions clean.
14. Fungus: Is there a Fungus Among Us?
Fungus is seen on fish weakened by stress, illness or injury.
A healthy goldfish won’t have fungus.
There are many kinds of fungus that show up in different places.
Here’s the good news:
Nearly all of them have the same symptoms and respond to the same treatments.
What are those symptoms?
Symptoms:
White, cottony growths on the body or fins are a sure sign that your fish has Fungus.
If the case is really bad the fish may act droopy or lose interest in food.
On a fish like that Fungus can spread FAST, so you will want to act right away.
Treatment & Prevention:
Clean water while you treat for Fungus will make it much easier for your goldfish to recover.
Make sure the water isn’t very cold, too.
Pimafix (a natural anti-fungal medication) will usually bring things back in check.
Fungal diseases are brought on by factors like bad water quality and poor handling.
Knowing this, you can avoid these problems in the future.
15. Tumors: These Bumps are NOT Normal
When cells are multiplying out of control, a tumor is created.
Goldfish can get tumors, too.
And in some cases, they can be cancerous.
They can also grow to get unbelievably huge, FAST. And multiply in number.
Goldfish can get tumors on the inside of their bodies or on the outside.
Some tumors even blind a fish by blocking its eyesight!
It may take a bit, but they DO kill goldfish if left untreated.
That’s why you need to keep reading.
Symptoms:
It’s easy to tell when a goldfish has a tumor.
A small lump starts to grow on the fish, usually on the head or body.
The growth may be pink, whitish or even black.
It could be lumpy like cauliflower or smooth.
Sometimes the fish won’t eat or seems depressed.
Treatment & Prevention:
If the tumor is hanging on by a thread, you might be able to snip it off quickly.
Sedating the fish with clove oil can make this easier.
Now I get that not everyone is comfortable with doing this.
That’s when you might need the help of a veterinarian, if you have one in the area that sees fish.
Because exposure to poor water conditions and a diet laced with preservatives in the fish food can cause tumors, keep the water clean as a preventative. Some are caused by a virus so you can’t really do much about that.
16. Carp Pox: Warts that Don’t Come from Toads
Viruses in goldfish are becoming more common.
Carp Pox is one of them.
It is usually seen on goldfish kept in ponds, or even in aquariums.
Nobody knows how it spreads.
And this is good:
Carp Pox WON’T kill your goldfish.
Want to know the weird part?
It can totally disappear only to come back later!
Symptoms:
Carp pox looks like smooth, white or pinkish “warts” on the edge of the fins or on the body.
Treatment & Prevention:
There is no absolute cure for Pox…
… And there’s not really a way to prevent it either.
But if you’re desperate, here’s something you can try:
Put the fish in warm water in a bath of at least 80 degrees for a while. Adding a fish-safe salt may help.
17. Lymphocystis: The Stressed-Out Virus
Like so many goldfish diseases, this virus attacks a weak and stressed fish.
It’s similar to Carp Pox in just about every way.
Symptoms:
The fish will have white, crusty lumps growing on (usually) the edge of the fins or even on the scales.
These “tumors” are shaped like a cauliflower.
Treatment & Prevention:
Bathing the goldfish with a chemical called acriflavine is recommended.
With any luck, they will go away in a short time.
Because it is a mystery how goldfish viruses spread, the best way to prevent them is to keep the water clean.

Are struggling with this whole “goldfish thing” and feeling a bit lost?
Or want to learn emergency CPR for your goldfish, and the biggest mistake most people make when they encounter a problem?
Good news.
You can learn exactly what you need to do in The Truth About Goldfish eBook:
I have a 16 gallon tank with 2 gold fish in it. I didn’t want to and I knew I shouldn’t, but I was talked into taking another goldfish from a neighbor who was just in a bowl it’s entire life and she wanted a better life for it…..he was shy at first and within weeks became dominant. He would ram my other 2 fish and I noticed that were staying at the top with their fins clamped as he had the swim of the rest of the tank. I tested for poor water quality and everything came back perfect. Then I noticed he was “biting” at one of the others. I took a closer look and my pearl goldy is missing a huge patch of scales just behind it’s fills on one side and and just a few in the same area on the opposite side. I immediately took the bully fish out and tried to find him another home. The other fish that wasn’t being terrorized as much is now swimming the tank freely and no longer clamping it’s fins, but my injured fish is staying at the top, still clamping her dorsal fin and now I see that she is missing a large section of her tail fun. I don’t think it’s tail rot as it’s a large section, but I do notice a tiny bit of a fray on the other healthy fish’s hind belly fins. Help, do I have a disease or super stressed fish?
Likely it’s stress. Not only from the bullying, but from an overload on the bio system with a crowded tank. I’d watch the water quality VERY closely and keep an eye on things.
Hello Pure Goldfish ?
So I recently added 4 oranda goldfish to my 60 gallon. The tank Is cycled and everything. Two of the goldfish where from a tank filled with disease so it was a risk buying them but I felt so bad for them. I added them to the tank and they were doing just fine until a couple of weeks ago my male oranda developed an ulcer on his head right by the nostril. Since the other fish started picking on him I put him in a 10 gallon and added medications against bacterial infections and I’ve being doing a lot of water changes. Since the medications didn’t work I added garlic to his tank for 5 days. I’m not sure if it’s healing Though ☹️ I really do not want to loose this fish. What more can I do to make him recover?
Sorry to hear that, Hannah 🙁 Definitely try to keep his water as clean as possible, maybe swab the area with hydrogen peroxide if possible being sure not to get it in his eyes.
Hello, Pure Goldfish! I just want to ask what is the solution for my oranda that is just floating, but still alive, and it seems to be just plainly floating, but she does swim a bit, then she will float again, and my fantails, have red blood marks on the scales, and the other one on her tummy. More power!
Have you tried testing the water for ammonia and nitrites yet? Red blood marks are usually from water quality related issues.
hey! i got a gold fish that i adopted for free because it is sick! it laying on the bottom and gasping for water im really hoping to save this guy!
Test the water if you haven’t already :))
i put him in a floater if you know what i mean and hand fed him for a couple of days he looked slim and i was waiting for the worst after school then i see him swimming happily !
That’s great to hear! So happy.
nvm! i saved him with tender loveing care!!!!! im so happy that i named him spirit!
Yay great to hear Jack!
Hi. I have a really big fish tank. I just got 2 new Orandas. Though one of them just stays in one place it doesn\’t move much some time he moves around. I\’m kind of worried cuz it keeps on spitting out his food instead of eating it. I really don\’t want it to die.
Also, I have another Oranda and his stomach is getting bigger and bigger. It keeps floating to the top of the tank. I searched it up and it says that the symptom is called fish bladder or something like that. I don\’t know how to get rid of it. If his stomach keeps on getting bigger he will die Please help me
This could be from a number of things, overfeeding could likely be the culprit. Start by testing the water.
My fish’s mouth is red is this normal? I’m worried about my goldfish. Thank you if you tell me.
Could be the start of mouth rot
I’m on the 2nd set of my fancy goldfish. Seems they keep developing ich. We did what the pet store said, add medicine to the water after taking out the carbon filter. We checked the water and bought a new filter and an air pump. The tank is only 10 gal and I was reading that the small environment might be causing them stress. After their 4th ich treatment, one looks worse with a frayed tail. It looks like the ich is still there. I would like to know if we’re doing it wrong…
Ich can be hard to beat. My preferred treatment is salt. You can read about it here.
That’s what I thought. I have not reintroduced the bully fish and won’t be. I’ll do another water check and change today. I added fresh water without a vacuum the other day and treated with the water conditioner and my orange perked right up. I’ll vacuum today and hope for the best.
Vacuums are great at keeping the water clean 😉
I have bought about 5 goldfish from the the store. I have 10 all together they was doing alright for a minute. One or two of my was dieing. Then my other fish eyes we’re looking bigger than the other. So I found this website about pop eye. I use the the salt 0.3 in my tank will it help the others. So how long will I see results.
Thank you
I HAVE A 10 GALLON FISH TANK
Hi Helena. =) So you have a 10 gallon tank with 10 goldfish in it? That is definitely overstocked, so most likely what happened is you have a very high level of ammonia or nitrites in the tank, which stressed the immune system of the fish and caused a secondary bacterial infection. In that case salt won’t be able to do much if your water quality is not where it should be. It is recommended to have no more than 1 fancy goldfish per 10 gallons of water to avoid that happening. Hope your fish recovers soon!
I think I burnt my fish with putting salt in my tank came home and there is a big hole in my black moor gold fish eye it’s white and I don’t know what to do take it out it’s misery or will get better
He might get better if you can keep the water quality under control, but if his behavior is bad off it may be kindest to euthanize. :/
how do you go about euthanize a goldfish?
You can use clove oil, following the instructions on this video.
Hi,
This site has been so helpful in helping to figure things out .
But I cant seem to figure out this issue .
We had added the water conditioner 24 hours before the fish came and and on Sunday night the filter was added .
That night the fish was added into the tank.
We added our goldfish into tank and he seemed pretty happy, he was a little shy at first, he was swimming in the corner of the tank, and would eventually, swim up and swim around.
But with a couple of days in, we noticed something weird, he would swim in the bottom of the tank, he would turn in circles, and then eventually swim to the other side of the tank. So we thought he would be fine.
What we noticed was when we fed him he would eat a little, but we weren’t sure if he was eating much.
But then , yesterday, night I noticed he was hanging around the bottom tank more than usual.
Then before I left, he was wrapped around the filter, so I turned off the filter, and found him dead.
I noticed when I picked up him he had a green tint to the bottom on his body, it looked like slime to me , but I am not sure.
I am just trying to figure out why or how he died.
Also, when we received him he did seem stressed out and looked like he was on his last leg , but then we changed him into a bigger ‘home’ it was about 1.5 gallon tank. Then after, when we bought the ten gallon tank, we switched him to that.
I hope this is enough information !
Thanks for the input !
Sorry for your loss =( Sounds like a case of new tank syndrome to me, Graphics. Very common if the system has not been cycled first. That process takes many weeks. The results if you don’t do that are often sudden death, because the ammonia surges quickly to levels that are fatal to goldfish.
Heeeeelp! I observed that My telescope eyed goldfish Got cloudy eyes at first but then after a week one of its eye popped it got a hole and i can see the intestines inside its head! :'(
What would I do to prevent other fishes in my tank
That doesn’t sound good, bianca. Cloudy eyes are often the result of a burn or injury, often from bad water. Keep your water clean to prevent your other fish from having that problem.
i have two black moor fish.one of them started getting sick, the fins on tail started rotting, i don’t have fish salt or kit. then the fish could not move properly it was always on his side. it always was near the heater. then it could hardly move, on next day i found it brown and dead. now the other black moor fish tail fins is started rotting. i put a medicine which is”M-I” for fungus, white spot and velvet. am i doing right? please help me also have 6 balloon guppy, three gold fish, two angel fish, but two balloon guppy i found dead possibly of same not sure, they had given birth before. my tank is three foot long and 1.5 foot high there is alot of space and my temperature is 29 Celsius always. there are pebbles in it which were collected one year ago. and fake plants.
also any tips to how to keep tannk clean and know for sure it is clean
My advice would be to take out the guppies and other tropical fish, Sufyan. Goldfish should only be kept with other goldfish. You most likely have a dirty tank. Water changes on a regular basis with a siphon is very important. You should also test the water regularly for ammonia, nitrite, nitrate and pH so you will know when something isn’t right with the water quality.
i do not have kit and equipment ,i only have net, methane blue , antichlorine and anti fungus but no other tank , i have 1 foot tank but we are keeping the babies of the guppies in it. and the fish store does not sell kit nor fish salt. i have been told black moor fish is very sensetive but temperature remain same now how do i test my water and i use a filters and pump.
Temperature really isn’t as important as water quality for goldfish. You don’t have to have a test kit, in fact (confession) I rarely use mine 😉 If you suspect a problem, change the water and keep changing it every day using a siphon at the bottom of the tank. You may want to take back all of those tropicals to the store or find them a new home. They are only contributing to the waste load of the tank and often stress the goldfish out by picking on them.
i noticed that my black moor fish fins edges are turning white. is it bad or good
also it keeps its fins low,i guess you call it clamped
Yeah, those are both bad signs that there is a problem with dirty water.
Hi Clemente..
One of my goldfish got bumps on his side more like white bumps..he still moving and eating..what medicine would be good for him?:.im going to do water change as I think I been feeding them too much and made my water bad really fast
Hey Nico =) If your water isn’t perfect, don’t mess with medicines. If you have been overfeeding what you need to do is get the water quality under control by changing the water very frequently.
Hi,
We recently acquired a common goldfish this fall that my son had won at an event. Purchased a sarasa to give him a friend on black friday. Since then I have been trying to educate myself reading up on different articles online. I purchased aquarium salt, stresszyme, pH kit, a hob filter (big enough for 30 gal.), air stones. I also bought a feeder comet that I felt sorry for and figured if he died, my loss would only be 15 cents, and he wouldn’t get eaten. They are only in a 10 gal at this very moment because the larger tank I acquired needs resealed. So while I am working on getting them a bigger house, I am doing frequent water changes with a siphon (old hose), and doing my best to keep the waste level down. However, since I do not have a kit to test for nitrite and nitrate levels, I don’t know what my water quality actually is, but still doing multiple water changes a week, if not daily. My issue with this is they are flashing and darting , and the little comet is trying to rub his side on objects occasionally. The sarasa does have white or cloudy spots on some of his fins. They all are missing a few scales, but are all getting along, have good appetites, and do not act lathargic. The pH is always 7.6 or 7.5 and they do have a heater that keeps the tank at a steady 73°F. I started feeding them small goldfish pellets to help keep the mess down. I know I need the kit to check ALL of the water levels, however, I’m trying to wait till after Christmas to purchase more necessities. What do you recommend to keep their stress down and how to go about their health issues in the meantime?
Sorry this is so long! Lol but the comet did rip his tail fin all the way up to the meat, and he was bleeding. I put some salt in to help with healing. He healed really well, and had grown back together in 2 or 3 days. Aside from the dark coloration from the blood in his tail, you wouldn’t have known he had an injury. Thank you for your time and any input is greatly appreciated! 🙂
If you see flashing, you’ve probably got an ammonia problem. Until you can get the test kit I would advise changing the water every day. If you don’t, they could end up getting to the point of no return :/ But good job on getting a bigger tank, that will really help! 🙂
Ok that’s kinda what I was thinking and why I’ve been changing the water regularly. Plus the tank is relatively ‘new’, and had only been set up for a week or 2 before the first fish was added, so I guess I’m probably dealing with new tank syndrome? I’ve been a little heavy on the stresszyme to help get things going. I was told the bigger tank is a 20 gal, but I’m thinking it may only be a 15 :\ I haven’t measured it, but, it’s still bigger till
I get another one as they grow. I’ve read up on different types of diseases goldfish can have, but their symptoms sound like it could be a few different things. so I’m wondering if it is just the ammonia, nitrite, and nitrate levels and possibly NOT bacterial?
Yep, you’re probably right on track there.
Hi Pure Goldfish, i have no siphon. my three goldfish, and the black moor fish died suddenly they were just fine 2 houes ago. one time i kept 12 goldfish and theh survived a long time together they died of old age. i have the tnk for a year now but nothing like this ever happened before. also the roof above have termite in them. and the powder that falls everyday. each day i clean it. but some of the termite powder fell into the tank while they dig into the wood. could it poosibly be that they are dying of that. and i dont have a siphoon. i guess i will buy one now. now i just have 2 angel fish and 4 balloon fish whose tails fin are rotting. i guess if they all die i will clean the tank fully.if the fins are rotting could it possibly be fungus oor is it termite powder. i dont have siphokn and i am not using the undergravel filter i am using the other one which you attach at sides.
black moor fish is like a blac goldfish with big eyes. i just read article that you should not put goldfish with tropical fish for 7 reasons does black moor fish count as gold fish. now i won’t put goldfish with tropical fish .only tropical fish is that good enough .will then my fish die or not. Thank you very much. you know alot about fish and how to maintain them. also ph value should always be 8. i will bye a kit for that. now i will kewp angel fish, balloon guppies, platee and betta .thank you. now i know i can always ask you for advice even though i am muslim no offence meant to you. thank you very much
how do i clean my tank if i have no salt i wanted to ask
last line last part was my brother not me
Don’t worry the sawdust won’t hurt them. What is most dangerous to them is their poop. If you aren’t siphoning the bottom of the tank than it just builds up and builds up until it kills them. That is why they have to have their tank cleaned every week with a siphon, usually 50% to 90% of the water. And clean the filter. Yes, black moors are goldfish not tropical. You are welcome to ask me for any advice you need 🙂 And for your brother, you don’t have to have salt to clean the tank. Cleaning just means you take out dirty water with poop and replace it with fresh water, making sure there is no gross crud anywhere.
well what i normally do is i shake the gravel then i scoop upmthe poop with a mug once a week. i will try to but a siphoon but i am saving for x box. if i get money i will buy. but what my brother does is that he puts then in a bowl and washes the the whole tank completely every month. with the gravel . its not good for the fish. so is doing this risky or not. i also read if one is sick try the shedded frozen pea trick
Afraid frozen peas don’t do all that much. Clean water is the trick 😉 Siphons can be made yourself with a piece of tubing if you have to. What your brother is doing is not necessary if you have a siphon. But I think you will find that gravel is hard to clean. I don’t recommend using it at all, if you don’t have to.
I have two black moors and their tank is WAY too small, it’s only 17l. I’m getting a 112l tank next week which will be 24g. Still too small but better.
One of my fish was floating at the top so I fed him peas and he went back to normal for a day then was floating again. So I fed him peas again and once more he got better…then went back to floating. He’s now lying at the bottom of the tank with clamped fins. I didn’t feed him the past three days and when I tried to feed him peas today he wasn’t interested.
I think my other fish is becoming less active and I’m worried about him being ill too.
My question is, what should I do and will they survive until I get my new tank? Tanks take a while to cycle don’t they?
Change the water every day, would be my advice, Rosa. They will only survive if they don’t get poisoned by their waste, which is what happens many times in a small space. Tanks do take a while to “cycle” but you can work around that by changing the water constantly.
Yeh I’ll definitely start doing that! So when I get my new tank, I should be able to put them in it soon if I do constant water changes?
Also I want to get rid of their gravel, because I think it’s bad for them but I’ve heard that taking it out can release a lot of bad bacteria and kill them. What would you advise?
You’re looking at about 90% daily while the filter is going in order to do that. No, I’d get the gravel out because if it has bad bacteria it is already leaching into the water. Then change the water afterwards.
Okay, how long should I do that for?? And should I let it cycle for like a day first?
Should I change ALL the water after I remove the gravel or just like 50%?
Usually it takes several weeks for the system to mature. I would do 90% after taking out the gravel to get that water extra clean.
I found scales of my goldfish at the bottom of my tank. Should I be worried? I live in Malaysia. And I really appreciate ur information here.
Are you sure they are scales, Sunny, and not teeth? Goldfish do lose their teeth occasionally and it is quite normal. But if you see gaps in the scales on your goldfish you are looking at a water quality problem most likely.
I have 2 goldfish and one of them has small things growing on his head. It looks like there are fish-eggs growing on top and there always start growing more. I don’t have the feeling he is feeling sick, he still eats well but I’m starting to worry about him. Could you help me please?
Sounds like it could be a tumor, Beth. Those are usually an indication that the water quality isn’t right. I would suggest testing the water and then changing it right away.
I’m taking care of my friends fish while she’s out of the country. There’s 4 gold fish and one white one. (I’m not sure what kind) as I don’t know much about fish I’ve realized they are acting really weird. The white fish stays at the bottom of the tank and doesn’t move. It has a red patch on the top of its head and for not knowing much about fish I know the tank is really small to be holding five fish. It’s probably a gallon and a half I’m not sure. But the white fish swims vertically at times and I don’t really want to spend money on them because like I said they aren’t my fish. I know her parents will be disappointed if one of them ends up dying. She said they’ve had them for about two months, what do I do with the white fish??
You’re in a tough spot, Carolina. All you can really do is try to change the water for them, making sure there is no waste at the bottom and that the filter (if they have one) is cleaned with tank water. Likely they are suffering from an accumulation of toxins in the water. You could also not feed because feeding will lead to higher waste production and faster deteriorating of the water. If you aren’t familiar with water changes I’d be happy to elaborate.
Please do if you don’t mind.
Sure =) You would need some kind of a siphon, maybe if the tank is small a turkey baster would work. Suck off the bottom where the waste is accumulating until about 1/2 the water is emptied. Then you would replace the water you took out with tap water treated with some kind of chlorine remover. Hope that makes sense, feel free to ask if you need further clarifying.
HELP! I just realised that one of my 3 goldfishes has bright red sores on its body. I just came back from a holiday, and I kept them fed during that time using a 7 day fish feeder (it’s some sort of block that releases food and nutrients into the water). I now realise that the ammonia is crazy high, 80 mg/L. I’ve changed the water and added these blocks that lower the ammonia level. The pH is at 7.8 but it is normally a bit high in my fish tank (I’ve also added dome buffer to lower it to 7.5).
I think that the red spots are ulcers, and I’ve just read some scary stuff about them!!! They look very painful and I feel terrible!
What should I do?
Will she be okay?
Thanks!
Ammonia can cause those ulcers, Mira, so I would be sure to change the water every day until it gets under control. As a side note that’s why I don’t recommend automatic feeders. Be sure not to overreact and start doing all kinds of things, just focus on pristine water.
hi Pure Goldfish now only i have six balloon mollys left. i am trying to make a siphoon out of old hose. i changed about half of my tank water. now i am waiting until they pass. after that i will wash my tank completely then siphoon the gravel. then i will keep tropical fish but I have a question can tropical fish live without salt in a freshwater aquarium.
Yeah I think tropical fish are fine without salt. They aren’t brackish water typically. Sorry to hear you’re leaving the goldfish hobby =/
goldfish are not my type of fish. Also the tank gets dirty real fast.thats why i am leaving goldfish
That is usually a sign of overfeeding…
we were out for the day today and just got home a bit ago, i noted that my posd commet had what looks like a lrg zit on his side that is pisging one of his scales up. this was not there this morning when i fed the fish. the fish is the size of your hand and its rather alarming. i have never seen this type of thing on my fish before so i’m not sur what it is or how to treat it. we have a full complete tank change plained for saturday as its not possable to due one till then. any ideas of what it may be. i looked up comon illnesses but it seems like none of them. i’m puzzled. any help would be great. thank you! kim
It could be the beginning of a tumor, or an isolated bacteria infection. If it begins to turn red and eat away then it is an ulcer. Are you doing weekly water changes?
I NEED HELP BADLY!!! I have two fish, one is a goldfish and the other is a white fish I don’t know the name of (it has some black streaks on its tail and looks like it doesn’t have any scales???). I have had these two for about two years. I believe both of my fish are terribly sick.
My goldfish has basically lost almost ALL of its colour. It (don’t know its gender) is normally always excited to see me when I feed them but now it just hides from me. Its breathing looks laboured. Its fins are completely fine and normal, only that it is white. And due to it being white I cannot see if it has an ich or a carp pox. Its fins are also not clamped. But what bothers me is that on its left side, some scales have fallen off! Its behaviour is “looking normal” when I am not near but when I come close, it just rubs its nose against the glass but then swims away and hides. It is not eating as much as before.
My white fish always hides from me until it sees food. Sometimes it ignored the food as well. But the main problem with this fish is that it sometimes flashes against the glass and the rocks (I don’t have gravel). And I also notice that when I am not there, it stays on the surface (goldfish does it a bit as well). Its fins are fine except for its tail that always looks droopy, not sure if this is normal for this fishes specie. Fins aren’t clamped as well.Its breathing is also laboured, much like goldfish.
I actually don’t know the size of my tank but it is quite small. I wonder if it is way too small for these two. I use white rocks on the bottom instead of gravel. And because I am a beginner on this stuff, I have a water filter and water conditioner and nothing else. I do have some hiding places for them. I am wondering if I need light because the tank is on a shelf next to a plug-in for the filter (and the filter doesn’t seem to be doing its job well…). I don’t know how to clean my tank properly either and I don’t understand “water changes”. I don’t have any other tanks. I feed my fish with this stuff called “Goldfish Granules” to both of them twice a day.
I don’t know what I can do! I’ll be leaving my fish for two weeks on the 8th of Jan. Not sure if they are going to live long enough for me to come back. I just want to know what disease my fish has because I have been searching and examining for hours but I can’t make a single match. I am starting to feel very emotional about them…
Well, Sparky, water changes and water quality are the key to goldfish health. If the water is bad the fish will be sick, it’s not usually (actually, almost NEVER) a disease. Your fish sound like they are suffering from high ammonia or nitrite levels. I’ll be coming out with an article on the subject soon, but for now know that for a properly stocked tank (for 2 fancies you should have at least 20 gallons) you should aim for removing 50% weekly with a siphon from the bottom and replacing with treated tap water.
Thanks for the info! I am aiming to get all the equipment I need as fast as possible. I’ll try to treat the water and control the ammonia and nitrite levels and see what happens next.
Oh and one more thing! What exactly am I removing 50% of?
Water/poop from the bottom of the tank 😉
I finally got the stuff I needed and can already see an improvement between the two fish. But will my goldfish regain its colour/scales?
Yes, with good care the scales can grow back and colour will return to normal =)
I just wanna ask, how long does it take for my goldfish to regain its colour and scales? Because its appearance has not changed whatsoever. And also, I have been doing 50% water changes once a week (kinda, just got back from a 12-day holiday 2 days ago). Is it better if I do more water changes? If so, how many per week?
Yes more is always better. Theoretically every day would be just dandy, but most people don’t have that kind of a schedule. At least be sure to do it weekly at all costs, but every other day or a few times a week will give you even more success.
i never have a dirty tank. i due water and tank and filter changes usually on a reg basis. i have a fluval for a 100gal tank and i only have a 20gal tank so it keep it very clean. its weird cause it litterly looks like a big fat ready to pop zit. any suggestions on what to due. were going to due a full tank/water and filter change on saturday morning, can’t fit one in before then as we have a big newyears eve and new years dinner family thing to due. is there a treatment for this type of thing? or something i can due for the tank in case it spreadt yo my other fish as i have a comunity tank.
i due have to admit that the tank was supposed to be changed 2 weeks ago but with the hoildays we had to put it off till this saturday. due you think this will go away or clear up if we clean the tank fully and due a full filter and water change. or due i need to get some sort of meds for the tank?
A daily water change of 25% or more would be even better than a full one. In fact that is what I would do in your place if at all possible. 99% of the time water is the reason why goldfish have problems. If the water improves they usually get better, it isn’t something that meds can help most of the time. You could also test the water to see if something is off, but even so, water changes are the treatment that will do the most good.
Thank you we are going to due a 50% water change today, but i noticed that one of the filter ports was clogged almost completelytoday with plant stuff think the pond commet guy that is sick broke off a bunch of the plants and they all got sucked into the one side of the filter. so i need to due a full cleaning to get the hoses off and everything unclogged in there. its not clogged right at the opening eather its in a bit were the hose bends upward slightly, not sure how long its been like that eather. i’m thinking its the issue. i removed alot of the ornimental stuff from the tank a month or so ago, caues the fish is sorta bit for the tank now and he was for ever banding into everything. her comming on 8 years old now so hes a big sookie baby. an way last night i noted stuff somming out of this thing i said looks like a zit, now today it looks like its a bit better, the scales are not bulged out so far andthe zit thing looks better than it did. is this a bad sign that its getting worse? due you think removing the 2 scales that this zit thing is under will help it get better? or should i just leave it alone. sence i’m changing the tank on Saturday anyway due you think a garlic treatment would help boost the fishes system a bit to help beat this thing at all?
my homecare support worker is here right now and she said it actually looks like one of the scales might be infected to here it want it looks like. is there some way i can add a picture of the fish you can view to see the thing? thank you!
You’re welcome to start a topic in the forums where you can upload photos 🙂
I would not do anything to it. No, I wouldn’t add garlic, I would focus on keeping that filter clean and the water quality pristine. If you do that the goldfish has healing agents that can repair the damage and recovers best without doing other things. Only if you are sure the water is perfect for a while and the fish still does not recover should you seek treatments.
ok, thank you i will try all that and if it has no effect then i’ll be back and with pictures. you have a great new years. kim
Need urgent help…
My gold fish is not moving or floating… It’s not eating as well…I am worried …also I can see its tail is getting red…please help
Likely you have water quality trouble, Rajib. Change the water right away and do so each day until your fish improves would be my advice =)
Hello,
I have a single 3 year old fantail goldfish named Chumlee in a 10 gallon tank. I was doing 40% water changes/gravel vacuuming every two weeks. I added prime to the new tap water before it went into the fish tank.
Christmas Eve when I went to turn on the light and found him at the bottom in the corner with his tail slightly bent and his top fin down. I went to the Internet and it recommended more water changes so I vacuumed the gravel and removed 40% of the water.
I noticed a improvement but not back to normal.
Since the 24th I’ve done a 40% water change every other day.
I add prime to the water before I add the water to the tank.
Today I went to the pet store and had the water tested, everything was good. They told me to stop the water changes and to start doing them once a week. I showed them photos and a video of Chumlee, they said he looked normal.
He’s better but still not back to normal and sometimes lays still at the bottom of the tank with his top fin down.
If he is at the bottom and I get his attention he comes to me wanting to eat. He’s still eating his food. I feed him once a day.
When he’s not at the bottom of the tank he’s his normal self.
Is there anything else I should be doing? I don’t want him to suffer.
Thank you for your time.
Hi Jim, my advice would be to remove the gravel entirely. Pet stores don’t tell you this but it is a trap for debris and a breeding ground for anaerobic bacteria. No matter how much you vacuum it’s just about impossible to keep clean… bare-bottom is the best way to go. As long as he is doing poorly I would recommend doing daily water changes and reduce feeding. Go by the condition of the fish, not just the test results, and only reduce the frequency of the water changes when you are confident he is better. You may also want to check out the feeding article to make sure you are on the right track with how much he is getting. Get well soon, Chumlee! =)
Pure Goldfish,
Update. I removed all the gravel and have done 40% water changes everyday. Chumlee is still the same.
Today I did a 70% water change and cleaned the filter in the extracted water.
I feed him Tetra Color sinking goldfish granules. I’ve cut back on the amount I usually give him. Now I give him 3 granules one at a time to make sure he eats it. He has had none in the last two days.
The only positive has been when I gave him 2 ends of a half of a pea, that was yesterday and today.
After the pea feedings he stayed off the bottom for two hours straight each day.
He still comes to me when I am in front of the tank.
From what I’ve researched I know I have to get Chumlee a 30 gallon tank. I would like to make sure he’s going to survive before I do. However if you think the current size of the tank is causing his problems and a larger tank will make him well I will make the purchase.
I think I’ve come close to reaching the end of the internet where goldfish are concerned. All that info can be so confusing.
I appreciate all your help and think I will just ask you when i have questions.
1. What brand of pellet/granules should I be feeding him?
2. Should I stop feeding him anything for a few days?
3. Would Fish medicines help?
4. Should I leave the tank light off until he’s better?
5. I follow the instructions when using Prime. Should I use more? Would it help or hurt?
6. Would adding salt to the tank help?
I’m getting both my tap and tank water tested tomorrow. Thanks again for your help. Jim
Yeah, there is a lot of conflicting info out there so it’s easy to get overwhelmed.
Regarding your questions…
1. I recommend the high-quality kind sold in our store.
2. Yes, when you have water quality problems don’t feed.
3. No.
4. Yes.
5. You could use up to 5X the strength of Prime safely, but I think water changes get to the root of the problem better.
6. No, salt will only cause more stress if there are no parasites.
Regardless of the test results (which can vary based on the time of testing) I would continue to change the water until you see improvement. It may take some time. Hopefully Chumlee recovers soon, I’m rooting for him! 😉
Pure Goldfish,
Good Morning.
I just checked on Chumlee and he’s now struggling against the current the filter creates in the tank, that’s never been a issue. Is it ok to turn off the filter? Even for a little awhile? Or is the filter helping to force water over his gills in his weakened state?
Jim
Yes, it is important that if the fish is having difficulty swimming against the current, that the filter flow is reduced or even eliminated. If they are struggling that means they are getting stressed.
Pure Goldfish,
Update, Turning off the filter seemed to help Chumlee swim easier when he comes off the bottom. He only leaves the bottom to greet me, hoping i give him food. I looked at a video i took of Chumlee a few days ago and his swimming is weaker. I’ve been doing 30% daily water changes. Is 30% a day to much or not enough water? last night I covered the tank with a towel hoping it might reduce Chumlee’s stress, will covering the tank help?
Tomorrow evening will be 3 days without food. the last 2 evenings there were fresh fish droppings in the tank, i vacuum them out when i do the water changes. Should i continue not feeding him? or start feeding him again, fish food or peas?
Thanks for your help, Jim
I would do at least 50% changes daily if it were me. As far as the peas go, I don’t recommend them especially when having water quality problems because they are so high protein and tend to cloud the water. Don’t feed as long as you are in the process of balancing the system; goldfish can live a very long time without food =) When you say his swimming is weaker hopefully that means in the video. Rooting for Chumlee! 😉
Chumlee Update 1-24-16
After my last post Chumlee got a lot weaker. In the morning I went to check on him and I got no response for the first minute, I thought he had died during the night. After a loud tap on the tank he finally moved a little.
I did a 40% water change.
After the water change I went to the local pet store fish section. Luckily for me the person who was in charge of the health of the in store fish was working that morning. I gave her Chumlees history and showed her the videos. I told her the water was spot on. The first thing she asked me about was what I was feeding him and how old was the food. Chumlee is actually 4 years old. I took over his care from my son a year ago. I called my son to find out how old the food was and to my surprise it was already a year and a half old when he gave me Chumlee, the food was 2 1/2 years old.
I didn’t think Chumlee would survive another night so I asked her what food she would recommend and if there was any fish meds that might help. She showed me a high protein fish food and a medicine called KanaPlex.
After thinking Chumlee had died and I might have been starving him to death with bad food I made the decision to feed him for few days with the new food to see if I could get his strength back, it worked. He improved to the point where I felt comfortable enough to give him the KanaPlex.
Chumlee has had the 3 doses of KanaPlex and has been eating his new food everyday. I’ve been doing one gallon water changes for two days in a row to clean out the fish poop and 40% water changes on the third day. I’ve been on this schedule sense I went to the pet store.
I’m happy to report that Chumlee is off the bottom of the tank and is 80% back to normal. He seems to be getting stronger everyday.
I’m on a fixed income and have been looking on Craigslist for a 30 gallon tank so I can upgrade the size of Chumlees home.
I want to thank you again for all your help! Jim
Great, glad he is doing better! Hope Chumlee does well for many more years to come. 🙂
Pure Goldfish,
Chumlee update 3-9-16
I’m happy to report that Chumlee is once again healthy and back to normal. I’ve upgraded from the 10 to a 36 gallon tank. The transfer went smooth and he loves his new tank.
I now feed him twice a day and do once a week 10 gallon water changes.
Thanks again for your helpful information. Jim
Awesome to hear that, Jim! 😀 Glad Chumlee made it through!
Pure Goldfish,
For the most part during the last year and a half Chumlee has been healthy and happy. Two months ago Chumlee started having swim bladder issues, no matter what I did to help nothing I tried worked. Sadly, on August 29th Chumlee past away.
After I adopted Chumlee from my son he became part of our family. My wife and I found ourselves watching Chumlee swim and play forcing us to rewind our DVR because we missed part of the program we were watching.
Over the years when Chumlee was sick I would video him with my iPhone so I could show the workers at the pet store what was going on. I would also video Chumlee when he was healthy so they could see the difference.
This is Chumlee during healthy times.

I’ve been looking in pet stores trying to decide if I want to add one or two Fantails to my empty fish tank. Chumlee will be hard to replace.
Thanks again for your help back in 2016. Your advice and your website helped give us a extra year and a half with Chumlee.
Jim
Aww I’m so sorry to hear that Chumlee passed away :'( My sympathies are with you, it is so hard to lose them!
Hi I really need some help 🙁
I have three fish and two of my fish have ammonia poisoning. I realized today and moved my one good fish who is a male. I will also inform you that the fish were in cold water for two months and I wanted to breed them so I turned up the water. One day immediately after I put up the water, white spots appeared on the male, and i’m not sure if these are breeding stars or not. there are quite a lot of these spots on him though. Anyway they were in my tank and then I realized that my fish started laying on the bottom of the tub, with clamped fins. I do 90% water changes once a week. I want to know how to cure the poisoning but I don’t know how. One of the poisoned ones started getting better, and the other started getting worse. What should I do? please please help me. I don’t want my fish to die ;(
Are the spots on his gill covers and front fins? If so they are probably breeding stars. To cure ammonia poisoning, what you’ve got to do is daily water changes of 50 to 90%.
Oh, and reduce feeding 🙂
I just got 10 goldfish last night at around 7:30 and I came home and put the bag full of them into the tank full of water and at 10:00 I opened the bag the temperature in the tank was 71 degrees Fahrenheit. Last night at around 12:00 I liked at them and fed them for the last time that night and noticed one little fish sitting at the bottom of the tank not moving, I took the net and tried to move him but he wouldn’t move so I sat there and watched him for about 10-15 minutes and he was moving but very little. I thought he was just shy but I don’t know and this morning when I woke up I looked at them fed them and the fish was still sitting in the same spot. I didn’t know what was wrong with him/her so I moved him/her into a smaller container with no other fish and gave him some food because he wasn’t eating in the other tank. He/she has big black spot on his sides and black on the tip of all his fins and 2 little holes a little bit above between his eyes. I feed all my fish 2 times a day once in the morning and once at night and I long give them a little pinch. I am feed them Goldfish Flakes.
What size is your tank, Emily? And did you cycle it before adding the fish? Either way by adding 10 fish all at once there is probably a huge ammonia surge going on.
Also all the other fish are swimming around just fine but that one. Also how can you tell if a goldfish is pregnant or not??
Goldfish can’t be pregnant because they don’t bear live young, they scatter eggs into the water which are fertilized outside of the mommy fish’s body =)
It is a 5 gallon tank. I’m only 12 what do you mean by cycle it before adding the fish and huge ammonia surge mean??
Never mind I think he just died???he’s not moving or breathing???
Sorry to hear about that Emily =( That is so hard. Ammonia is something fish produce with their waste. It quickly builds up and if the water isn’t changed a lot then their waste can poison them. Cycling the tank is a process that “conditions” the tank to be ready for that ammonia when you add fish. Hopefully you are able to try again in the future.
they are not only on his gills and fins they are all over his body and also on his tail and top fin
In that case it may be ich you are dealing with…
Hi there. I work at a family owned fish/pet store and I have a few tanks of my own as well, yet this is the first time I have ever seen a goldfish come down with what mine seems to have. I have it narrowed down to either tumors, flukes, or ulcers, or maybe a combination. I got my goldfish George from Wal-Mart (I know I know) about a year ago and he’s been growing up super fast and pretty healthy. Unfortunately I also had two large bully goldfish whom I recently got rid of (gave them to a friend who has a pond) and they used to tear at the fins of everyone else in my 40 gallon tank. Now that they’re gone and I added new fish about 2 months ago, George seems to have come down with something bad. While everyone else’s fins healed up, George’s fins got worse. And he started getting multiple bumps on him. He’s always been a little chubby and he’s starting to look slightly bigger in the belly than normal. He now has an ulcer which I either see pus or a worm sticking out of at times. He is in a mesh net hanging in his normal tank, so somewhat isolated. I’m thinking about taking him to work with me and treating him with antibiotics and melafix. He barely moves but still has a normal appetite. I can give you a link to some close up pictures I took of the ulcer and bumps if you’d like to see them. Do you have any idea what this could be?
Hi Kalina, I do have a few ideas but I would need to know a bit more about your water change schedule, feeding schedule and if you have tested the water yet for ammonia, nitrite, nitrate and pH. You are welcome to send me a picture if you open a topic in the Health Concerns forum =)
I do a 10-15 gallon water change every three weeks. I feed once a day usually, but I hand feed each fish so that there isn’t waste. I gravel vacuum on a weekly basis and change the filter cartridge when it starts looking a little dirty, so every two to three weeks. I have a combination of fish that most fish keepers wouldn’t be happy about (4 small goldfish, three guppies, two angels, a pleco and a female betta) in my 40G hex tank. I give the goldfish flakes and pellets, and I give the Angels and betta a mix of blood worms and pellets. I feed once a day, although sometimes I feed half amounts twice a day. I test my water myself regularly and all is normal. Once every two months I bring it to work and have it tested there. I have had my tank running like this without problem for a year, I recently added two fish right before the problem started.
I should also note that there is no aggression in the tank between anybody so I very highly doubt this being bites from someone else in the tank
I would definitely advise upping the percentage of water you are changing to at least 20 gallons twice a week for the # of fish you have, and cleaning the filter whenever you clean the water. I think your system is overloaded, and you’re right about most people probably not being happy about that mix of fish ha ha. 😉 You may not be open to this but if it were me I would take out the tropicals and put them in their own tank. Angel fish become very aggressive with time and plecos are notorious for sucking goldfish at night. Nobody can always watch the tank 24/7 to see if bullying happens, often the fish are distracted when people are in the room so they don’t fight.
So do you have any ideas on what those bumps could be? And I’ve had quite a few years experience with tank keeping, I keep it at a temp that’s good with everybody. %50 water changes a week will send my system way out of balance, because the tap water around here takes 2 weeks to treat properly so adding in the harsh metals and chemicals that come with it, even after treating it, in a heavier scale and more constantly than normal will do nothing but hurt my fish, as I learned during experience with the first few tanks I have. The water quality is perfect so I think I am keep doing what I’m doing as far as water maintenance. Plus, I do water tests very often and it has always been fine, and wouldn’t the rest of the fish have problems if it was water related? I did have a Chinese algae eater who I recently got rid of, and those are known for sucking on fish, but my other fish don’t show signs of being hurt by the big pleco. Also my fish tank is in my bedroom which I’m in for about 6 hours a day, awake, at varying times of the day with the lights both on and off, so I get a LOT of time to observe their behavior and I assure you that there is no bullying going on.
Well if you don’t have a good tap water source than yeah, more water changes aren’t ideal. You’re kind of in a tough spot there. In my opinion (though it’s hard to say much without a photo) the bumps are either immune responses to injury or a response to an overloaded tank system. Water testing is not what you go by if the fish isn’t well; the rise and fall of the presence of toxins can make it tricky to get a read. But plecos are famous for flank sucking, all algae eaters are really. They are attracted to the slime coat and sooner or later it happens, maybe not yet for you. If you have an algae problem nerite or apple snails might be of assistance =)
One of the ammonia ones, the stronger ones tail color is starting to fade away and become clear. will this improve?
My advice would be to keep changing the water each day, and reduce feeding as you are doing. Be sure to take out any gravel at the bottom of the tank and clean the filter frequently in old tank water. Sometimes color changes happen as a result of a shock in water quality or change in lighting or environment. Test & change, test & change to be sure there is no more ammonia =)
How can you tell if a goldfish is male or female
Males will have white speckles in breeding season on their gill covers & front fin rays. Females may have a lopsided look from above with a larger vent. Sexing goldfish is not easy even if you are a professional =)
My fish lays on the bottom of the tank and she breathes only from her gills. Her gills are getting big and are not closing when she breathes. She also does not open her mouth. And she lays on her side and moves not that often.
Hi Fluffy Panda, I think you might have a case of water poisoning on your hands. Change the water right away would be my advice.
Hi, I have a 28 litre tank with 4 small fantails in it, have only had for a month or so one of my fish gills on both sides have gone dark red and very small marks on head. Is behaving normal. What could it be? How do I treat?
Sounds like water poisoning to me, Clare. I’m afraid your tank is far too small for the number of fish you have so the waste is accumulating in the tank. What I would advise is changing the water and getting a bigger tank as soon as you can. Feel free to ask if you have more questions =)
I have 2 goldfish. A Comet and a fantail. I got them about a week ago. The comet has a black unclear spot on its tail. This spot has moved by itself and also when we tried to pick it off (we thought it could be a worm). It seems to be under the skin as well. The fish just hangs around in the top corner of the tank for about half of the time. We’re treating the water for high alkaline Ph levels but we’ve only just started doing this. They’re in a 21L tank.
What exactly is your pH, Duckboi?
One of our goldfish has white spots on it’s mouth do have any idea what the problem could be and how we could treat it?
You might want to upload a photo of that by creating a topic in the health concerns forum, Geoffrey, so I can better see what you are talking about. =)
Hi, at what point do you know it’s time to euthanize? I have a very sick fish, he’s clamped at the bottom with labored breathing and then has “bursts” of movement when he swims and breathes only to go lie back on the bottom. We saw what we feel was an anchor worm on him late last night and even watched a “piece” break off or an egg release, I can say which for sure. Seeing something released, I did a 50% water change and added the only available treatment, API General Cure, last night and removed the filter cartridge. I want to give him a shot and dose 2 of the medicine would be tomorrow but not sure if he’s past the point of no return and I should just euthanize?
That’s always a tough question, Jen, but I go by if the fish eats and how bad it looks… sorry I know that’s vague. But something you might want to make sure of is that your water is in good shape, because what you saw may be an anchor worm but it also could be the slime coat of the fish shedding in response to stress. A shot will do more harm than good if the issue is the fish’s environment, which is the case 99% of the time.
Hello Pure Goldfish,
My almost six year old goldfish Trish appears to have an infected scale. I noticed at first a scale looked damaged or puffy. Now it seems to have gotten larger, almost like a wart. It is turning a dark gray. Trish is acting normal and happy. She lives alone a 10 gallon tank. Can you give me some advice? THANK YOU!
That almost sounds like a tumor to me, Nancy, especially if the fish acts fine. There isn’t a whole lot you can do for those.
Bleak news but thank you.
The good news is you can typically slow the progress of one by making sure your water quality is good =)
We have a horrible situation going on. We have a 20 gallon tank that had 5 goldfish in it and a catfish. The goldfish are small and have lived together for awhile – they have enough room and have been quite healthy and happy for a long time. In fact, even with our newest edition, all was well for over a year, then we stupidly added a pleco and he stressed everyone out. We removed him (and put him in another tank) as soon as we saw signs of ick a week ago, but now we’ve lost 2 of our beloved goldfish and the other 3 all look absolutely awful. We’ve had the water tested twice and have used medication for ick and an antibiotic, as well as stress coat and salt. Now we’re just using the antibiotic and the ick medicine. We’ve followed the advice of the experts at the fish store and we have had goldfish ourselves for the past 25 years, so we have experience, but nothing like this. We keep 3 tanks at home, but only this one with goldfish. The filter and set up of the tank is fine, but these fish are dying. All 3 of them are lying on the bottom gasping with ragged fins. 2 of them will come up to eat, but they just look awful. We’ve been doing small water changes as directed by the fish expert, but they don’t seem to be helping. It is horrible to watch them suffering and to be trying to do everything we can but not having any luck healing them.
That’s no good, K! 🙁 Well if you want my advice, I’d say first-off, do large water changes every day, at LEAST 50%, not small ones, and if you have gravel take it out immediately, and if you have a filter be sure to clean it in tank water thoroughly. Not sure if the catfish is still in there, but if it is I would get him out too. Catfish will grow massive and eventually become aggressive. Your goldfish are likely suffering the effects of a huge ammonia surge, as the tank was so overstocked that the waste built up to intolerable levels. Don’t go by water tests if the fish are not well; ammonia and nitrite surges can come intermittently between testing. Even 3 goldfish in a 20 gallon is more than recommended. Also, don’t feed while this is going on because it will only add to the bioload which is already strained and could tip things over the edge. Hope that helps.
I have a problem where my fish are dieing nearly 1 a week its not white spot its not the water iv tested its fine and none of my fish are bullying each other but they still keep dieing and instead of floating up when they die they go to the bottom incase that helps they have none of the other diseases or symtoms iv read above but they just keep dieing and i dont know what to do please help asap
How long has your tank been set up, Mitchel?
I have been set up for 8 months now
And, how big is the tank? How many fish are you adding at a time? And how often do you change the water/how much? And how much do you feed? And did I ask enough questions ha ha?
Its a 20liter tank i have 6 fish and i never put more than 8 in there so when i put some in its 2 to 3 at a time i make sure they climatise forst for atlest 2 hours i change the water roughly every 4 weeks some times earlyer some times later always making sure i dont have it pristine clean as they need some dirtyness i feed them 2 times a day and i make sure they eat all the food within 2 to 3 mins if they cant i feed slightly less to make sure i dont over feed . And any questions is fine i just need to know what im doing wrong if im doing wrong i hate losing fish 🙁
Just adding but there only small fish definatly not big ones or medium bigest fish is 4 cm long
Ohhhhh thanks that sheds more light on the situation. I can tell you what you’re doing wrong…
First, the tank is undersized for the # of fish you want to keep. Even small fish produce a lot of waste and ammonia via their waste & respiration. That is why no matter how big or small the fish are you still have to give them the recommended room if you don’t want things to go haywire. At least 40liters per fish for fancies.
As far as how often you are changing the water, definitely not enough goldies. They need weekly 50% minimum water changes, and there is no such thing as too clean of a tank. It’s a myth that they need dirtyness; dirtyness kills them.
I’m afraid they’re also getting too much food. Please take a look at our feeding article for reference.
Yeah so hopefully that clears things up. If you follow the guidelines laid out on my site and in the care article I think you will have much more success. 🙂
Ok thanks for your help 🙂 i was feeding them the recomended times a day i was told by my local pet stores did some looking into them befor buying and everyone said 2 times a day but thanks for clearing that up and question then if they need 40l then why do they sell anything smaller?
Sure! Hmm, why do they sell any smaller? Well, they sell. Someone deciding for the first time might want a cheap option. The bigger the tanks get (typically) the less wiling people are to buy them due to money/space constraints. But, taking proper care of a pet means they may have to get over that lol. And I think for two, chain pet stores really have no clue about a lot of aspects of goldfish keeping. They’re business experts, not animal experts.
Thanks for all the help iv just rushed out and baught a bigger tank to suit them 🙂 nother question how oftern would u recoment feeding your fish peas and letus ?
How do u recomend water changes in warm water fish ?
Awesome, they will appreciate it =) Um I don’t ever recommend feeding peas really. Not a good choice because they are so messy and high protein. But the lettuce, they should have access to that 24/7. Can’t ever get enough of it 😉 For warm water fish, do you mean tropicals? I am by no means an expert in that sorry to say ha ha.
Yes tropical fish where i live we have warm water cood water and tropical but i did some research and found out about warm/tropical changes and i think i will be fine thanks for all your help ??
hey, Pure Goldfish;
thought I’d pop on and thank you for all your help.
My big girl left us on tues morning!
We did that full tank/filter cleaning and the full water change as I said we were. an I have been doing daily water changes and all that stuff, our tank water is perfict now as it normally is. all the fish are happy and normal.
big girl seemed to due better and the spot on her side never got worse and for the most part looked better, but yet never got better. she never did start eating again, she moved around and stuff like she was fine, but at feeding time would just go hide head down in the back corner and come back out after about 5mins or so, when feeding time was done. then finally sometime over night on Mon she finally got to her weekest point and stopped being able to keep herself upright. When I noticed her belly up at top of the tank struggling to move, it was clear she was near the end, she was prob in that situation for hours, before I noticed her. I held her cupped in my hand best I could for awhile, bt you could tell she was having trouble breathing. it was kind of a rasph squeeky sound, like she had fluid buildup or something, she struggled with every breath.
She dyed cupped in my hand after about 1/2 and hour or so. once I found her I didn’t want to leave her to go by her self. It was a bit hard and awkard as she just barely fitting in my hand, but she seemed calmer in my hand. I didn’t want her to go all stressed out and struggling in the tank all upside down and the current banging her into stuff, with the other fish picking at her.
I feel bad for my corydora though as big girl and cory were pals and were always playing chase and cory used to groom big girl and they slept side by side, it was cute that they kind of had a friendship of some sort. being 2 different types of fish and all. but they did all the same. Now cory is going all nuts in the tank she keeps breaching to the top of the tank and she is at the glass swimming and squiggling back in forth all crazy like and swimming laps like she is looking for something. I guess she is missing her buddy.
I know how she feels I’m missing my buddy as well!
any way, thank you for your advise and help.

Sorry for your loss Kim 🙁 It’s hard when they don’t make it.
Hi–
I have an almost 3 year old petstore goldfish. He is quite small, maybe 2 inches long, as he is kept in a small tank (I clean it frequently but my parents don’t let me get anything else). Today I noticed that there are 2 red bumps, one on the back fin and one on the front of the tail. Each is about a 1/4 inch tall. I am not positive but I think that there may be a small tear in his tail as well. Part of his tail appears a bit more red than normal.. it may just be the coloring but it may be blood?
Swimmy is acting completely normal.
From researching and reading articles on this site, I am hoping it is just Carp Pox, but I am worried it is a tumor.. what do you think?
I would love to do anything possible to treat it. The reason I am not sure if it’s a tumor is it doesn’t look like a gash, more like a little wart. Also, I was thinking I could try and salt my tank. I have never done that before.. I use normal tap water with a chemical from the pet store to make it fish-safe. Will my gold fish be safe in salted water? What kind of salt, and how much?
Thanks for the help.
If there is any way I can attach a photo, please let me know.
Thanks,
Annie
If it looks like a wart, likely that is a tumor. Carp Pox not very common. I would not try salt if it were me… I would go for trying to keep the water quality better by doing lots of water changes so the bumps don’t get worse because bad water is a cause of tumors. You are more than welcome to upload a photo in the forums =)
Thanks so much! I have 2 more questions:
1) You mentioned to do lots of water changes. How constant should I change the water?
2) On further inspection, I think Swimmy has fin rot.. the tip of his tail is a lighter color and it is splitting. I saw you mentioned a swab and baking soda. I have never swabbed Swimmy before, and am worried about hurting him? Also, do you just put the baking soda straight into the water?
Thank you,
Annie
Hi Annie, sorry it took me a while to answer you. I moved hosts on my site so things were a bit crazy for a bit!
1) Every day if possible, and the more the better, as long as your water is from a good source.
2) If your water quality isn’t 100% perfect, don’t add anything or swab anything as goldfish can heal on their own most of the time as long as the water quality is good.
You’re welcome 🙂
Hello , my goldfish isnt eating for 4 days now & I just noticed small circle of redness close to its tail , what should I do ?
If it were me I would change the water, and cut back on feeding because overfeeding can lead to a lot of issues with water quality. You may also want to check out our article about that.
Hi Pure Goldfish,
I have one comet goldfish who is about 3-inch and one shubunkin goldfish who is maybe 2-inch in a 10 gallon tank (I know this is too small but we plan to move them to a 20 gallon when we can and I do water changes almost daily until we can get a bigger tank). We recently had a bully fish that stressed my goldfish out by chasing them during the night but he was quickly removed from the tank. Before this they had been treated for ich (a couple months ago) and then fin rot with melafix and Pimafix and those issues seem to have stopped. What I can’t figure out though is why my comet is losing scales on one side of his body (about 1 per day) last night I caught him rubbing on gravel and the shubunkin has a small tear in his tail that won’t heal. Besides this they have been acting normal happy as usual and their water tests always come back nearly perfect. Help please these are my babies and I can’t figure out what is going on :c
Hi Jessica! 🙂 How much water do you change at a time, and how often do you clean the filter? Also, do you have gravel, and what is your feeding schedule like? In that size of a tank (which you are right for planning to get a bigger one) keeping things under control is going to be a challenge…
Hi there.
My son has had his 2 goldfish for 3 years now and they have never had any problems but today we noticed that one (Edward) has developed a very sore looking red eye on one side. It also looks like there is a skin covering it… He appears to be fine otherwise but we are concerned about him just the same. Could it be that he has injured it on one of the tank Decor or do u think it could be something more?
It is possibly a reaction to bad water, or a secondary bacteria infection, Debbie. I would lean towards thinking it is not an injury. Those kinds of symptoms are more of an issue if something is not right with the tank itself.
So I have 3 fish in a 10 gallon tank, I know that’s a bit too much but I make sure to do regular water and filter changes and watch their behavior often. So one fish a couple weeks back starts getting black spots and after some research I think it’s ammonia burn. I am disappointed in my bad tank keep up but I do more frequent changed and remove old food and all of that. More spots. I keep doing research and I feel it can’t be my tank conditions. This is one of three who is at all acting strange and he is looking rough. He lays at the bottom a lot and today I even saw him on his side. I’m afraid the end is coming but I really don’t want to give up. Please help
Don’t give up! 🙂 How often are you changing the water, Megan? And it is also possible your feeding schedule might be playing into things.
He is looking really bad. On his side and won’t get up for food. I have had him a year and haven’t changed anything. I try to do a majority water change each month but little ones in between that. I also try to feed them pees occasionally, recently I was out of pees so they didn’t get them. Would this cause it?
Thank you so much for replying! I do about 20% water changes daily, my goldfish get fed flakes in the morning but only a tiny bit because they are pigs haha, they also get 2 crushed and shelled peas 2 days a week as an alternate to flakes. Right now I clean their filter about once every week. I have gravel in with them and I do have a gravel vacuum, I was thinking of using that to do the water changes as well instead of scooping the water out. The 10gal tank is pretty new so the gravel is still very clean, we would like to get a 20gal we just need to make more space.
Also I talked to a local petstore today and they recommended giving them API stresscoat plus I gave them this today and it seems to have reduced the flashing a tiny bit already. Also my fish get a small dose of marineland aquarium bacteria everytime I do a water change
If you haven’t been using the siphon to vacuum the gravel, chances are you have a large amount of decaying food and waste in there that is continually being released into the tank. My advice would be to remove the gravel completely because it is a problem-causer most of the time.
Hi have got a goldfish who has got a Gill tumour. I’ve read that iodine medicated water could help but how much do I add to the water? Want to help the little guy if possible. He eating normally but is swimming tilted to one side. Thanks
Tincture of iodine is used as an isolated treatment for disinfecting, but I don’t think it will be of much help for tumors as tumors are not infection. Clean water is really the only thing you can do, to stop the progress.
Peas*
Also, is it safe to do a water change with him so sick? I don’t want to stress him out but it is time.
Peas aren’t really the best choice for goldfish food anyway. In fact they contribute to problems more than they solve any, in my opinion. Without weekly water changes, that is probably the reason your fish isn’t doing well. If you don’t do them now he will likely not make it, just be sure to not move him out of the tank because moving the fish can stress him out.
I believe he is gone. His breathing was incredibly slow and now there is no signs of breathing. I was told peas were good for a once in a while feeding to help with nutrients but I will end that. Is there a way to tell what went wrong? I feel horrible that I was unable to figure it out. Thanks for the help.
Sorry to hear that 🙁 I believe it has to do with your setup, feeding and maintenance schedule. You are right that the tank is undersized; for 3 fish in a 10 gallon, you would have to be doing water changes at least every other day to keep the ammonia at bay. If you are removing old food that means there are leftovers, and if there are leftovers that means you are overfeeding as well. That will add to the ammonia output which is already greater than the water volume permits. I’d highly recommend taking a look at our feeding article, and upgrading to a size of at least 20 gallons, and then you will be able to cut back the water changes to once weekly if you do at least 50% at a time. Not sure if you have gravel, but having a substrate is usually also a source of problems.
Should I give them sand instead or just give them new gravel?
Bare bottom is what I recommend.
Ok thank you! I will try that. One more question, what kind of food would you recommend, I have heard many different views on pellets and flakes and am not sure what would be best
Pellets are what I recommend 🙂 If you haven’t already I would really advise checking out our feeding article.
My goldfish has one eye, and has developed black scabs and lost scales.
any ideas?
He has white salt like grains on his tail and dorsal, I gave him multicore for a while, but it didn\’t go away, and then he developed the black scabs.
I keep getting different advice, don\’t change the water, change the water, don\’t remove the snail, remove the snail, remove the decorations, don\’t remove decorations, don\’t keep multi curing, don\’t use algae control, the tap conditioner has caused burns.
He seems happy, he eats well, he is a bit of a bully, but that\’s ok he is about 4 x bigger than the others, and he is my main priority.
He was in a smaller tank until yesterday.
I have a pineapple decoration that has pointed bits on top. (sponge bob\’s house)
There are 3 decorations, gravel, a lot of other fish (probably to many) and 2 filters, one that makes bubbles. and a snail, oh and a PH oxy shell.
The other fish include, 2 black widows, 4 other small gold fish, a zebra danio, and another little one,(yellow with a black dot on his tail)
I don\’t know what\’s wrong with him but the more I research the more problems he seems to have.
Like black smudge, ammonia/ ph burns, white spot or ich.
sometimes he swims tilted to one side, I thought that might be because of he\’s vision, but that can also be a symptom of swimmer bladder.
Does he have 4 separate issues? or could it be that because of his poor vision he has knocked off his own scales and caused the black scabs?
Just an FYI I don\’t actually know if One eye is male, we just call him, him.
It sounds like all one problem to me, Kat – poor water quality, especially if you are seeing black smudges. Exactly how big is the tank? That could definitely be a factor, along with how often you are changing the water and how much at at time.
So I add a medicine to the fish tank because my fish have this problem .so my question is that should the medicines meant to be blue
If you are using methylene blue, yes… but why are you using it?
Okay here it goes….
I had five fish in my 20 gallon tank, four gold fish two of which were white, and an algae eater. They were fine until the last week. Now I did loose four goldfish earlier, due to poor health conditions from the store I got them from but the tank has been throughly cleaned since then.
This past month was when it all started. Miles, the algae eater began to act strange by swimming up near the top of the tank before he passed on. Next came Billy, one of the smaller gold colored goldfish. He hung out around the bottom and hide under the rock most of the time before he hid in the corner where he lay on the rocks. He never floated when he died. He just lay there on the bottom of the tank until I had to remove him. Up next for the flusher was De Logo, which meant from the lake in Spanish. He was swimming happily when I when to spend the night which my aunt, but when I came home my mom and brother told me he was sick. When I checked on him he was dead, with a white mucus sort of film on his gills and mouth. Sort of like when a human gets the cold. So I started to watch the other two, and yesterday morning found the larger white one, Sammy, dead. He too had the white film on his gills and mouth. Now I have one left, Tiny Fish Tim. He has been moved from the big tank into a small tank that I have cleaned daily. I have a bubbler hooked up to it as well and I feed him accordingly.
So back to the larger tank. It has gotten really cloudy in the last week. Like can’t see the bottom cloudy. This is not normal seeing that I have a filter in it all the time and try not to over feed them. I have not had time to clean it yet but I just cleaned it last Saturday! The temp runs about 68 degrees Fahrenheit most of the time, and non of the tanks around it have anything like this going on and I cleaned them at the same time. I use the same water for each, the only difference is that the other fish are bettas not goldfish. I have not put anything new in the tank, such as rocks and decorations.
Is there any thing you can tell me that might save my last little goldfish?
That’s quite a situation, Claudia! How much do you normally change of the water and filter, and how often? I think your fish have suffered from overcrowding and water poisoning (and likely overfeeding, but you would have to confirm that from our feeding article which I highly recommend reading). What you will need to do is change the water every day and clean the filter every day until things even out and the system balances.
Alright. I clean the tank almost every weekend and the filter as well. I feed my goldfish about every other day and not that much because they did not seem to come up and eat. The other thing that worries me is that this has happened to a ten gallon tank that I only had one fish in and it was in the same spot that this new tank is in. Could it have anything to do with location?
Nah, it wouldn’t be the location to cause those symptoms. Most people actually don’t realize they are overfeeding, which is why it’s important to have a frame of reference. If you have a substrate be sure to get rid of that too.
Could it be ich? Most of the fish that died where the most healthy of the bunch as well. De Lago was the biggest and most active where Tiny Fish Tim is small and he is always at the bottom even now in his new tank he hides at the bottom. And he does not eat any more.
Well I feel stupid. It’s a 30 gallon tank not a 20 we had a 20 gallon.
Probably not ich, probably water quality. If the fish doesn’t eat don’t feed.
My koi-fish seems to look like its bleeding. It’s dorsal and caudal fin has a dark-red tint to while the back-half of the fish looks,’ bloody ‘. I’ve searched tons of websites in a fast matter as soon as I noticed! Is there something wrong?! (( If you need anymore details I’ll gladly give you more. ))
P.S The koi-fish is orange (( with a hint of red )) spotted.
That’s often a sign of high ammonia or nitrite levels, Alexis. You will need to change the water right away and evaluate your tank setup.
How would you tell if your goldfish has flukes?
You would have to perform a gill scrape and analyze it with a microscope.
I’ve been reading the comments and I think I have an ammonia problem. I had 4 goldfish in a small fountain out back all summer and had to bring in when weather started changing because the fish weren’t doing so good and the water was getting difficult to keep clean and flowing. With new tank I quickly realized a 5 gallon was too small for 4 fish. After two months I added them into a larger 23 gallon biocube. I didn’t do any waiting period besides a day of making sure water was good. After that it took about 3 weeks before water went cloudy and has been going downhill ever since. Last night one of the goldfish died. The others had a cloudy color to them and swim back and forth eradically while opening and closing their mouths. I went and bought all these different types of chemicals because my water always tests hard and to much ph. Nothing has worked. Today after reading all these comments I think I made a huge mistake of not cleaning out the tank every week…? I’m trying to do this right but some people at pet store told me I didn’t have to do water changes and others say a little bit every once in a while. I’m thinking I need to do half the tank for the next few days. What do you suggest? P.s. It also got a bunch of algae in it which is mostly gone now after I did a half tank water change 3 days ago. Now it’s still very cloudy. Also the last 3 goldfish are possibly 4″ at the most. Help please?!!
Pet store people typically give water change advice for tropical fish… the majority don’t understand that goldfish are a lot different ha ha. For the next few days I’d definitely do 50% water changes every day, and only worry about the pH if it is too soft. Goldfish prefer hard water, and trying to change it can stress them out.
Hi ive got a goldfish in a 30lr biorb ive noticed a few white spots on its tail, its very active can tou gelp me? thanks
That may or not be ich, which is pretty common in pet stores. Please take a look at our article on it and compare symptoms. 🙂
I have 2 fish, 1 large fancy goldfish and one algae eater. They are in a 30 gallon tank. My goldfish has white spots only on his fins and some bumps on his dorsal fin. We have done the ich treatment as well as treating him for bacterial infection. They are still there, not spreading but not getting better either. I sent an image to an expert and he said it is not ich, but didn’t give me anything on what it might be. Any ideas?
White spots are an immune response, Gail, and could be a sign that your algae eater is inflicting small injuries on your goldfish which is not uncommon. I would highly suggest separating them as they cause problems with aggression sooner or later… they like to suck on their tasty slime coat.
My goldfish, despite changing water and filter recently, is listless at the bottom of the tank and is moving very little indeed. He’s seven years old and has been happy on his own in a nice big tank. I’ve given him a couple days without food and then some shelled peas but he hasn’t improved. Any ideas?
My first thought would be, what does your water test for ammonia, nitrite, nitrate and pH? If waste has accumulated over time than one water change would not be enough to solve the issue…
Hi there,
A week ago, my white panda goldfish got stuck in a shell and only noticed a day later. I managed to get her out but she was very dizzy, upside down, on her side, and her buoyancy was terrible. I just assumed it was swim bladder and so I started feeding her some frozen peas (skin off, boiled) and started swim bladder treatment about 5 days ago. She soon started to recover – her energy levels were up and her buoyancy improved.
However a week later, I am noticing that her scales are red..on one side… almost like a rash and her fins are fraying – she used to have a beautiful dorsal fin and now there is very little left. Also… she looks very skinny and losing appetite.
How can I save her?
Hi Sandi, did you try testing the water? Also, how large is the tank and how many fish are in it?
Yes I did I brought a sample to my local store and all is good ! Two baby fish (including the sick one) in 15l tank. She was doing so great before the incident with the shell ! Seriously the most energetic and friendly fish – they were the best of friends
I think your tank size is causing issues. For 2 goldies you should have at least 75 liters, otherwise there is too much instability in the system. The shell incident might have caused further stress on her already weakened immune system.
40 gallon breeder with 5 fancy goldfish ( medium in size) Under gravel filter with 2 power heads, 2 canister filters, fed Repashy gel food. Ammonia 0 Nitrites 0 Nitrates about 80 but drops a little after water change. Tap is at 20 nitrates. Minimum 50% water change twice weekly. Crystal clear water. One of the Orandas started showing a black speck above each eye. It has since turned into a dark colored eyebrow going deeper into the wen. Fish still eats, swims and has fins erect. If it wasn’t for the crevice in the wen, you would never know there was a problem with him. What do you think this could be?
Do you mean, is there an indentation in the wen? Or is the blackish colour just spreading onto it?
Into the wen. DEEP. Started Furan 2. LFS says its not hole in the head
You might try uploading some photos to a topic in the health concerns forum. I think I need to see this one.
Hello
I have a three black moor fancy goldfish in a 30 gallon tank. Two Butterfly tails and one ribbon tail… My ribbon tail’s lips is cloudy…. but not cotton like. I don’t seem to see any cause of this because I change my water 70% everyday because I didn’t cycle the water, but I always ensure that my water is crystal clear and always 0% Ammonia, etc. Please help me determine this or guide me on how to remove this cloudy lips of him because I’m a little bit worried that this might be a symptom of mouth rot or mouth fungi… Thanks in advance.
Has it always been like that, Osborne? It’s possibly natural lack of pigment on that area…
It happened this morning… How do I turn it back to normal?
I would just keep an eye on it. You sound like you are taking good care of your tank so most likely it is demelanization.
the brain of my goldfish is like popping out from the head HELP ! PLEASE
Yikes! You might want to post a photo of that to a topic in the health concerns forum. I think I’ll need to see it to tell what is going on.
Help! I saw a hair strand like worm in my tank… And I think it’s hidden under my gravels. Its swims like a snake and kinda freaks me out. Please help, because I don’t know if it’s dangerous for my goldfish and how do I remove it.
Sounds like planarian worms, a sign of a dirty tank. Take out the gravel and clean the tank more and they should go away.
Oh thank you so much! Your site is very helpful in fact, by following your instructions, my goldfishes are now living in years! So thank you so much 😀
I just bought a twenty gallon tank for my three goldfish and just this morning I introduced them into it. As I did so I realized that two of them had an irritated looking red spot on their heads, one of the two having some white looking substance covering the area. I previously was keeping them in a large pot since my old tank cracked. They were in the pot for for four days and it had gotten quite dirty but I thought it would be fine since they wouldn’t be in there for too long. Looking at them now they seem quite lively and don’t look sick at all. Should the spots just go away over time?
They should, as long as you keep the water in your 20 gallon very clean.
Hiya. We cycled tank before we got two gold fish in 10 gal tank. A week after they introduced to tank I noticed a white mark on the white fishes tail. Kept an eye on it everyday, a week later more marks have appeared on the same fishes tail and now dorsal fin. I can’t see any on body, and it doesn’t look like ‘salt’ so I don’t think its ICH? Or fluffy or anything like that? I think the edges look a little bit frayed, not sure tho as its hard to tell with white fins. Other fish seems fine. No flashing. No gasping. Water quality is fine, ammonia is slighter above zero. But no nitrite. Any ideas? Help I’m worried :S thanks
If your ammonia is above 0, that is definitely the problem.
Please help!
I got a 15 gallon tank from a friend who was moving on Monday set it up and added a Black Moore Goldfish Tuesday night. Wednesday morning the water was cloudy and now the fish has white stuff all over. Its not patches of white stuff almost looks like slime. From what I was reading I’m thinking it might be a Fungus and or Fin rot? He is swimming just fine he ate this morning. I got my water tested after I did a water change(not sure if that was a good idea) they said everything was fine. I got the aquarium salt. How long will it be till he gets better and how often should I be doing water change? what could have caused this? I don’t know what to do about the cloudy water I don’t want to add too many chemicals. Worried he might die. Any advice would be great! Thank you!
Could I have not cleaned the tank well enough to where it made the fish sick? was he too stressed out from the store to our home?
It’s possible, but likely the water is the problem.
Probably new tank syndrome, if you just set it up recently. Cloudy water is a big indicator of that too. Testing the water after the water change can lead to skewed results as far as understanding what your parameters are normally… my advice is to keep changing the water as often as you can until the tank is cycled, which will take several weeks for your filter to mature.
Hello 🙂 … One of my black moor’s scales is terribly knocked off… will it come back to normal? Do I have to medicate the tank? I’m worried that it might infect
Hi Joshua 😀 Missing scales are a sign that the fish is scratching on things in the tank, irritated by the water usually. The scales will grow back but only if the root issue is corrected. Medication might tip your fish over the edge.
Hello my fish had a white pimple like bump on the side of it’s belly.. I think this is a tumor. ): I have a calico fantail and one that looks exactly like your profile picture Pure Goldfish, that is the one that has been infected. I noticed it yesterday and it is about the size of a normal pimple you would get on your face. But when i came home yesterday i noticed that it has gotten worse. I asked my fish expert friend and she told be my fish has about a month ): I cant believe it!! All of the water conditions are normal and he seems to be happy! I have had them for about 6 months and i was just ordering a bigger 20 gallon tank for them! Please help what should i do??????
Hey Maddie, what exactly are your water conditions like? Did you test for ammonia, nitrite, nitrate and pH? I would definitely change the water either way.
Whats wrong with my fish if their tails looks like it breaks off and then just 2 days they die?
It depends on a lot of things, Venessa, but chances are high ammonia levels caused that.
My goldfish, Rocky, has stringy white trails attached to his to his tail fin, weird white cottony spots all over his body, and he also floats to the top of the water and just sits there, I have heated up the tank, added some salt, even given him a salt bath, but he still is not better! Is there anything else I can do?
It also seems that poor Rocky has given up all will to live, he just floats there and breaths, not really moving 🙁
Have you tested the water? It could be there is something very amiss.
Hi this page is very informative, thanks so much! I have a question though… I have a fantail goldfish with what looks a lot like a whitehead pimple on his head. It started out as a small dark tiny dot under the skin which I noticed about 2 weeks ago. In the past two days it has raised slightly and is ejecting white (puss? not sure) looking exactly like a human whitehead pimple. He is a mature male in a well cycled 40 gal breeder w 2 small ryukins (not sure of their sex yet) Water params are 0ppm ammonia 0ppm nitrite 5-10 ppm nitrate. Weekly water changes 50 percent or better w vacuuming the sand, and actually cleaning the poops out daily. Is it wen growth even though not oranda or lionhead? Is it breeding stars developing?Tumor? Thanks in advance for any help you can give 🙂
Sure thing 🙂 If you have a fantail, it isn’t wen growth. From your description it sounds like a skin infection or immune response of some kind. This is typically an indication that something isn’t right in the tank. Could be the filtration needs cleaning, could be more water changes are needed, could be from bad bacteria in the sand. No matter what the fish would benefit from larger, more frequent water changes until it clears up. Hope that helps 🙂
Thank you! I think your right about a skin infection as I wiped gently with a q tip and the white stuff was puss that came right off leaving a small raised bump and I can still see the black spot under the skin. Did a 60% percent water change last night and we are adding some salt and being vigilant about water changes. Btw the sand is not deep at all (about 3/4 inch) because of the risk of bacteria. The filters are pretty new as well. Thanks for your help and I can keep you posted if you want 🙂
Hi Pure Goldfish, I wanted to give an update on the “pimple” situation, lol. We added 1/2 tsp salt per gallon and changed the water 65% This worked wonders! Immediately the lump went down and after 2 days is gone. There is still a tiny bit of white left but it is almost gone. I just wanted to document this because I researched online for quite some time and couldn’t find this exact problem. Thanks again for the help! I am so glad we didn’t medicate him. I am changing the water today and tomorrow so we can reintroduce our snails (They are not very happy in the bucket right now)
I did have to learn a hard lesson through this though. I was trying to scoop poor Emerson with a net (he is super fast) and got his front spike of the dorsal fin caught in the seam. He was freaking out and the tip of his spike actually broke. I am devastated about this. Needless to say…. NO MORE NETS!!! Do you think that will heal back?? Thanks again 🙂
Good to hear! Usually if it is the leading ray of the dorsal bone itself, it won’t grow back sorry to say.
I’ve had 4 small swordtail fish in a 10 gallon tank for 5 months. They had done really great, even faring two relocations. I do 25% water change once a week, wipe down any algae on the glass, clean the filter, etc. They were doing fine up until about 2 or 3 weeks ago when my smallest one started acting strange. She’s gotten kind of grey on the top, she was breathing faster and showing a small red spot on the lungs. I feared I had ammonia poisoning so I got my water tested at this really nice pet store nearby. They said all my levels were perfect (no ammonia) except the tap water I was using had a GH of 0-1 and live bearers like 6-15. So i’ve been adding some equilibrium something or other to the water since then to raise the hardness. My other fish are still fine but she has just gone down hill. Taken to sitting on the bottom of the tank, not eating, breathing really fast. Today I noticed a red spot on her side by her fin and a red spot at about her chin. Her eyes seemed a bit cloudy. She can’t really swim any more and is just laying and breathing and I’m assuming will die soon. I want to know what happened to her so that I can prevent it from happening to my other fish! Did she have some disease that they might have caught? Any ideas greatly appreciated!
Hmm, to be honest I’m no expert in regards to swordfish, Kate, but it does sound like some kind of irritation from the water to me. I would change the water more often and try to keep things as clean as you can and see how that goes, as well as test the GH regularly in the tap and in the tank.
I have 2 pictures of my girls goldfish that is not acting right. Is there a way to send them to you? Thanks!
You can upload them to a topic in the forum and I’ll be happy to take a look 🙂
I am concerned about my small fantail Merry- the lower section of one of his tail fins in not opening to its fully extent. His level of activity has also dropped too (at the bottom more), though not drastically. No other signs of disease. It does not appear to be anything serious at the moment, but I want to heal him quickly. Things that might help you diagnose:
— I have had Merry for about 3 months- he is only about 4cm long.
–Merry shares a tank with a small Oranda goldfish since a month ago. Both get along well and the Oranda is perfectly healthy
–Tank is approx. 90L. Plan to upgrade the tank when they get bigger
–I do 30% water changes once a week when I clean the tank. I clean the tank with a Siphon to remove the fishpoop from the small layer of gravel at the bottom of the tank
–Last time I cleaned my tank I also cleaned my filter for the first time in 3 months. .I did not touch the charcoal but i squeezed the gunk out of the sponge and scrubbed down the algae on the filters sides.
–I tested the nitrate, nitrite, pH and anomia levels- the pH was a litter low (so I raised it), and the anomia was only slightly higher then usual, so I did another 30% water change.
I would be grateful for any advice!
Lara
My advice would be to remove the gravel and do a large water change – 90% – right away today and each day following, cleaning the filter with each water change. 30% weekly is probably not going to cut it, and your filter’s charcoal is probably long dead. It only lasts about a week. The gunk is highly toxic though, so you want to clean that out with every water change.
I have a 40 gallon tank setup with 85 gallons worth of filters, with a bottom feeder I just introduced, and 6 goldfish that are between 2 and 3 years old that I’ve had for a while. One of the older ones was white with orange patterns and over a couple months the orange colors have faded and it turned completely white, it’s behavior didn’t seem to have changed though. But now it looks like it’s right iris is misshapen and the eye has become cloudy. Also it seems to be swimming a bit frantically and nother swimming around as much as usual. None of the fish show signs of aggressive behavior towards each other. I havent tested the water, I need to pick up a kit for that.
I did a 25% water change last night, and am going to test the water later today.
Let me know the results!
Hi Pure Goldfish. Tnx for your useful articles.
One of my fantails is always swimming at the top of the bowl despite an air pump in the bowl. Also i think she has gotten fin rot. Her tail was white and now it is getting smaller.i almost change their water everyday. Sometimes she flashes away and her mouth shakes rapidly!
Pls tell me what should i do 🙁
Can you get a larger tank? Bowls just aren’t suitable homes for goldfish, but for now you can try removing any stones or gravel you might have at the bottom and continue to clean it daily.
Treat tank or continue with extra water changes? I recently purchased an Oranda from Petsmart. She has some issues and I want to make sure I’m giving her the best start possible in her new home. She is in a 55gallon cycled aquarium with a liohead purchased at the same time. I have a Marineland 200 and an Aquaclear 110 HOB filters. Ammonia is 0, Nitrites 0, PH 7.6, Nitrates 5ppm. The very tips of her fins have a white edging and are a little blood streaked above the white edging with what looks like a few teeny tiny longer strings of fin coming of where its white. She also has a 3 whitish spots on her fins that look like small pimples. I treated the tank for 3 days with Melafix after bringing them home. Do I continue to just keep the tank nice and clean or should I try a salt treatment, or another kind of medication? I honestly can’t tell if shes getting better or worse.
I would first analyze the setup before any kind of treatment. What is your water change schedule and feeding like, do you have a substrate and how often are you cleaning the filters?
I’ve been doing 2 water changes a week on Tuesdays I do a 50% and on Fridays I do a 25%. I clean filters once a month. I feed sinking pellets 3 times a day 3 – 5 pellets a feeding. I have a small amount of gravel in a couple dip bowls to anchor plants, a moss ball, and a few plants anchored with fishing line and aquarium safe rock and a bubbling volcano. I’ve had the goldfish for about 2 weeks now. The previous occupants of the tank were a rosy barb and 5 leopard danios but they were moved to a 29 Gallon a few days before getting Rosa and Nugget.
Temperature in tank is 72
Filter might be contaminated. They need to be cleaned as often as possible.
Okay, Thank you will clean immediately. Is there anything else I should do? Thanks for your help!
Just focus on clean water and not overfeeding 🙂
The three white spots have disappeared and her fins now look great. Cleaning the filters in used tank water twice a week during water changes. Thanks for your advice!
Awesome!
Hi there, my sons cold water goldfish has recently lost weight. It’s trying desperately to eat, but every time it does the food just comes straight back out of its gills. It also spends a lot of time at the top of the tank popping its head out the water. I have checked the ammonia levels and they are perfect. What could it be?
Hi Alison! What is your size of tank and water change schedule? Did you test for nitrite, nitrate and pH?
Will do! Thank You 🙂
Hi, do a full clean out including filter about every 4 weeks or so
ph 7.6
KH 180
GH 250
Nitrite (NO3) 25
Nitrite (NO2) 0.5
Two Minnows, one black moor and one inch long goldfish (the problem one)
If you have a nitrite reading, that is definitely a problem.
Ok so what’s the best way to solve it?
Water changes, and lots of them.
Thank you I’ll give it a try ?
Hello Pure Goldfish,
I am house sitting for friends and their goldfish, Goldie, is sick. They have told me they don’t know what is wrong and will wait and see. I fear that if they wait Goldie will die.
She is on the bottom of the tank, doesn’t rise up at all. She spends all her time in one spot, barely moving. She does not feed, even when the food floats down to her, and only moves when disturbed. Even when disturbed she stays on the bottom, moves about a little, seems frustrated, and then gives up and goes back to her spot facing the back of the tank. She has what look like two red growths on her head, above her eyes, they appeared in under a week which seems rather quick to me. She has no other symptoms that you mention in the list above. She is alone in a tank, not sure what size the tank is though I think it is sufficient space for her alone.
Can you please recommend something that we can try to help her?
I know that some owners make little flotation devices for fish who develop issues with floating. Would that help?
Hey Alice! Flotation devices will not prove useful in most cases of bottom sitting. It is a sign that something is wrong with the fish’s environment. First, if she won’t eat, definitely don’t feed. It will foul the water. Second, the fish is probably in sore need of a water change. If there is any gravel, remove it and replace 75% of the water daily. If there are any filters they will need to be cleaned in tank water. The red above the eyes are likely patches of fluid swelling behind the eyes, a result of water poisoning.
Hi Pure Goldfish,
Thank you. I have never before cared for a fish, other than feeding, so what is the difference between tank water and tap water? Does the tap water need to be treated with something before I replace the 75%? Also does the water need to be tested for pH or anything else? The owners will be back tomorrow, and they don’t have any water testing kits or anything for water treatment either. Also do I need to remove Goldie from the tank when I replace the 75%? I am asking you a lot of what are probably basic questions here, so if there is a web page that has all this info please feel free to direct me to that instead. 🙂
Also I have had a better look at her, and the spots on her head are not red they are the same orange as her own coloring, and they appear along her body as well and I think I see one on her top fin (right at the bottom of the fin, but not on the scales). Does this info change what you think may be wrong with her?
She is moving a bit more today, not sitting on the bottom, but still isn’t rising very far up at all, not feeding, and is not floating level in the water (head tipped down a bit).
Thank you again for your time and advice, I very much appreciate it.
Tap water typically has chemicals that will kill the fish. It will need to be treated beforehand, yes. The pH of the tap is typically fine for goldfish. You don’t need to remove the fish to do the water change. I’d take a look at our goldfish care page, if you haven’t already 🙂 You can send me a photo on our FB page, and I’ll try to diagnose. 🙂
my goldfish is sleeping too much …. and turns herself horizontally when she is not moving… and she is also not moving too much….. plzzzzzzzzz tell me what i do???
A little more information about your setup could help figure out what is going on, Annie, if you could supply the water parameters for ammonia, nitrite, nitrate and pH, tank size and water change schedule. Any more details would be good too 🙂
I have taken photos of Goldie, tried to get good images of her spots and lumps, but I don’t have a facebook page so is there an email I can send them to?
I have not changed the water as I have nothing to treat it with. The owners will be back today and I will pass on your instructions to them along with links to useful pages on this website. I did gave the tank (top plates of glass and top edges) a good clean yesterday, no chemicals just using clean moist cloths, as there was some dirt, scale, and even some old food stuck to the sides in one corner that had turned black. It seems they have not been cleaning the tank regularly.
That’s usually the case when a fish isn’t well. Sure, you can email them to info@puregoldfish.com and I’ll take a look. 🙂
Hi,
I have two goldfish in my tank. One of them, I’ve had for about two and a half years old and the other is fairly new, only a few weeks old, which i bought after another one passed away. The tank is clean and there is around 20 gallons, which I’ve heard is enough for two fish, and there is also a rock decoration in the center. But the older fish is always at the bottom of the tank, usually laying to its side (and yes it’s alive, it’s mouth is moving and so are its gills). Whenever I used to open the lid of the tank to feed them, it would always swim to the surface and wait to be fed, but now it just sits at the bottom.Its mouth is constantly opening and closing. Sometimes, but rarely, it will swim around the tank a few times or come to the surface for air which is when i have to quickly feed it before it comes back down to the bottom of the tank. I have noticed that the fins, especially the tail look almost like they’ve been teared, leading me to believe it is fin rot. But it didn’t mention anything about sitting at the bottom of the tank. However i think it may also be ammonia stress, as some symptoms for that are sitting at the bottom of the tank and swimming to the surface for air. I really hope that it doesn’t have both fin rot and ammonia stress, if that’s even possible. Any suggestions?
Probably it isn’t fin rot if the tail is shredding, that is just a result of the ammonia poisoning. Rot can set in though if the ammonia levels don’t get eliminated. Water changes and lots of them are what you will need to do.
Thanks heaps for the information, surely it’ll help ?
I have a gold fish he is about 10 years old he is developing black spots on his cheeks and now on top of his head they look like bruises or cancer or something has any one else ever seen this
Could be ammonia burns. I’d test for it and water change right away.
Please help! My gold oranda looks like his fin is peeling, but I can’t tell if maybe it’s actually something on his fin. He does have a weird bump in his other fin but I think that’s more of a birth defect. It doesn’t look like fin rot or ick. My other black moor doesn’t seem to have this problem. They are both very young, not even an inch yet. I’m really concerned about my fish, every source I read says “my fishes skin looked like it was pealing before it died” and I don’t want that to happen 🙁
Any ideas on what it could be and how to treat it?
Did you test the water for ammonia, nitrite, nitrate and pH? It sounds like it could be a pH or ammonia related issue.
My two weeks gold fish(Spilsh ) having red spot on his body since yesterday. Splish is in a 28L tank, I do 50% water changes twice a week with a syphon . Please help.
Is that the only fish in the tank? Is there gravel and how often are you cleaning the filter?
My two weeks goldfish -Splish having red spots on his body since Wednesday. Splish is in 28l tank with filters and live plants and one airstone.i did 50% water changes twice weekly but since last Wednesday I am doing daily water change with a symphony. Do I have to add medication for that red spots ? Thanks .
Question regarding the salt additives, do you need to use aquarium salt? Thanks!
No, you can use non-iodized sea salt (NOT table salt).
Hi Pure Goldfish,
Gravel and filter are clean twice weekly .
I added a K1 ceramics media filter before fish was introduced.
Yesterday the pets store informed that it’s a bacterial and they advised me to use anti bacteria and fungus fish treatment which I did last night and I have to wait seven days for the second dose .
I am confused now – can I change the water ?
I haven’t feed Splish since yesterday , water tested for nitrate: 0.5
Thanks
When doing treatment you can only change the water if you replace the treatment you took out.
Hi, I have 2 feeder fish that were in a turtle tank. The turtles never ate them so we moved them to a different tank. Now, one of them has a white bump over his left eye. Besides that, he seems fine. Please give me feedback. Thanks
The bump could be anything from a tumor to a fungal infection. You might try taking a photo and posting it in the forums so I can take a look 🙂
I have a question about an injured goldfish. We got him from a carnival 4 years ago. last night when I fed him he got spooked and swam frantically in his 10 gallon tank. He hit the sides a few times, hit the bottom and the tiny decorative bridge in the tank. This morning he would not eat and his breathing is labored. Looks like he is gulping for air. And I noticed streaks of blood in his tail fin. I cleaned the tank the day before the injury and tested the water and all the levels are normal. I bought API Stress Coat and put in his tank. Is there anything else I can do for him?
Clean water and avoid doing anything that could spook him are very important. It may be best to keep the lights off too.
Can i send a picture of my dead golfish most horendus sores and mouth problems i need to no what caused it so to avoid other pond fish having problem.
Not sure how to send you a picture
Sorry to hear that Lawrence 🙁 Sure, you can post it to our Facebook page or open a topic in the forums and attach it there.
Not to good with it how do i get to forums and open a topic?
I have tried to use your facebook page, please see if it has posted
Regards
Responded to you there 🙂
I have a 450 gallon outdoor goldfish pond. It is graphite lined, like a swimming pool. We’ve had it for a year, with 14 “feeder” goldfish in it, and so far everyone is healthy. But I’ve had aquariums most of my life, and feel like I should be changing out the water in this thing! There is a fountain aerator, and a filter, but the pond is “in ground”, so siphoning isn’t possible (that I know of). Also, I like to feed them every day. Is feeding bad? What should I be doing to maintain optimum water conditions? I live in New Orleans, but my pond in New York (no filter!) was a piece of cake!
I would definitely agree with you on that. There might be a way to siphon the water uphill, by angling down the hose 4-5 feet per foot of height you are trying to lift out of the pond. That, or use a submersible pump… which is probably the least productive solution.
Rather than commenting, I am crying out for HELP!
One of my gold fish has a disease that I do not know the name of. His mouth is growing together getting smaller and smaller, now it is tiny and I am injecting immense amounts of air into the water to keep the little guy breathing, feeding is a problem in that he can only consume fish food for kili fish, that I still have to grind down to allow him to ingest it through his real small mouth opening. The little guy is fighting to stay alive and I would really like to help him, but so far nobody I reached out to was able to give advice on what to do or how to heal or at least improve the suffering that my fish fell victim to.
Please, if anyone of the readers knows a way to help, let me know what I can do!
Thank you in advance
Without a photo it’s hard to know for sure, but there are two probable things…
1) Mouth rot or
2) Genetic mouth crumple
There is nothing you can do for the second one. It is a defect in some fish.
Hello again! 🙂 … One of my black moor have something whitish in his pupil… like a cataract. I’m quite disappointed because I always work hard changing half of my tank water like every single day (no skipping) to prevent any sickness and this cataract appeared just suddenly? What am I going to do? Please help 🙁 Thanks in advance too 🙂 Mabuhay from the Philippines 😀
Hi!
Do you have any gravel? If your water is fine and you’re not overfeeding it could be from age…
The tank is bare bottom and the fish is just 4 months old. Do I need to change their diet plans?
I would definitely check up on our feeding article if I were you to see if you are following that or not.
My tank is 30 gallon btw and has 3 black moors
Hi so I have a ryukin and he is in a 5 gallon tank and has a plecostamous with him and they get along. But my ryukin had some how lost a piece of his tail can u help me out.
Also he lost his tail before I get him his friend.
If you got him from the pet store like that, only time and clean water will help it grow back.
So i have 2 goldfish male and female i notice right away that the male would bully the female so i took him out when i took him out i noticed she was layin eggs so i put him back in to fertialize them but fou d him eatin all of em after couple weeks of her being alone i noticed 6 tiny babies swimmjng around like really riny so i left it as is i left for the weekend came back only to find my wife put the male back in and he ate all the eggs again and ive yet to see one of the ba ies now i tolx her to keep e. Seperate but again when i came back he was in the tank and now she has a huge hole on her right side and her insides r comin out well to a certia. Point wat do i do
If she has been injured that badly she will need medical attention. It may be there is no vet who sees fish available, if so it is kindest to euthanize 🙁
Speckles my goldfish has a ulcer and I am worried will it kill him!
Oh no! 🙁 Change the water every day, keep everything really clean.
I just lost all of my Gold Fish and one Coy to Dropsy. Dropsy is about the worse thing your fish can ever have and 99% of the time is fatal. I did not even know they had it. I tested the ph and nitrates and the water was always fine. The one think I did not do was isolate the first fish that got sick. If I did this then all of my other fish would probably be alive today. My gold fish were between 7 and 8 inches long when they died. I hope this helps you out and pray your fish never gets this.
So sorry to hear about that Ron 🙁 Dropsy is horrible for sure… probably one of the worst diseases.
My son has a 4 yr old goldfish that is 8 inches long and very active. He has a huge tumor on his side that was red and bumpy now it’s splitting and the inside looks white and very hard and dry, the fish eats like crazy and swims like a pro, any suggestions?
Cleaner water can slow the growth, but surgery is the only way to get rid of it completely.
My Gold fish have white thing on its scales and its growing its like flesh thing on its body
2nd is my fishes are not growing either its been more then a year and no growth
Do you mean a tumor? You can send a photo in the forums. Not growing could mean your tank is too small…
What an incredibly informative website!! I am trying to gain as much knowledge as possible to keep my 3 goldfish happy and healthy and in my reading I notice you are very adamant about getting rid of the gravel in the tank. I have gravel in my tank and am wondering what the easiest, most stress-free way of removing it would be. Any advice advice would be most appreciated! Also, as far as adding aquarium salt to the tank, how often do you recommend adding salt? With water changes only? Thank you VERY much for any advice you can offer!!
Answered you via email 😉
We got a goldfish from the pet store about 2 weeks ago and got a 1.5 gallon tank with filter for it. It is the only fish in the tank. We noticed one morning, 4 days ago, that her tail, finding, and spots on her body were starting to turn a slight shade of black. The night before, she was completely fine. I changed 40-50% of her water that very day, treated the water with AquaSafe Plus water conditioner and Top Fin nutrifying bacteria starter. However, each day, we noticed that our goldfish still continues to turn more black. The fish does not seem lethargic, still swims around, eats like normal and we don’t really notice any other symotors that could tell us what might be wrong with her. We would appreciate any advice you could give us as we are at a lose for what to do and what might be wrong! Thank you!

I have four big oranda gold fishes (about 6- 8 inch mouth to tail). I called an aquarium cleaner guy to clean the aquarium. I think he mis-handled one of the fishes and it got a scar on body just where side fins joins the body. It is not deep but wound looks reddish. Right now fish is as active as was earlier but I am fearing, since that part of body is in continuous movement, wound may not recover quickly. What shall I do to make it recover fast and ensure that things do not worsen.
All you can do is keep the water super clean and keep things calm for the fish. It will probably heal with time if the damage isn’t too severe, such as exposing muscle tissue.
Thanks Pure Goldfish for the tip. The aquarium is cleaned 4 days back only. and I am keeping filters and air pump switched on for whole day to keep it clean and well oxygenated. I will need your guidance if situation worsens. Although the wound seems to have healed a little today. It’s not looking fully red.
I have a goldfish with green “fuzzy mold” on both sides of his body. He is active, eating and swimming happily, but I am afraid for him and the other fish. I have read all I can find, but I am unsure of what it is, and what the treatment is. We have a 100-gallon outdoor pond with 11 goldfish. We replace the water by 1/3 daily due to evaporation or loss of water through fountain spray. Could you please help?
Thanks so very much!
Do you ever suck water from the bottom of the pond? If you are just replacing the evaporated water then the waste is only sitting in there getting more and more foul… this can lead to all kinds of diseases.
We clean the pond once a year, possibly twice. I don’t know what to do about the fish with the fuzzy green sides. Isolate it? Any medication? The water is crystal clear but there is a thin coating of algae on the pond sides (100-gallon plastic pond). Any recommendations?
Thank you for your help!
Best Regards,
Monica
The fish needs clean water first and foremost, or it won’t recover. Isolating it in a 40 gallon tank or larger would probably be a good step while you get the pond water quality improved, I would highly recommend cleaning it much more frequently especially with as many fish as you have in there. 🙂
I have 2 questions for you about stuff to give fresh water fish to eat. I read about this seaweed stuff somewere. I don’t remember were it was now and I looked an couldn’t re-find it any were, but this person said that every so ofter she crumples up brown marine algae which is a natural dried seaweed product into her fresh water tank to add a bit of salt into the fresh water to help avoid getting sick fish. and it provines the fish with a tasty snack too. now this seems wrong to me, but i know you can add small amounts of salt to fresh water tanks for a number of reasons and to help with some stuff. but can you really feed that to, and add that to a fresh water tank in small batches with out harming or even killing your fresh water fish? an secondly she said that she grinds up fresh garlic 1-2 cloves depending on size in a small amount of fresh water and gives it to the fish to eat every other month, its really good to give there systems a boost and helps get rid of and pests that may be in the tank, she gives this a day or so before she cleans her filter system. an she says it a tasty snack for the fish too. so are these things that we can give to our fresh water fish that can be treats to eat? if so are there other things we can feed out fresh water fish that are not tipical pellet or flaked fish foods bot in shakers or dried in packages? thank you! kim
Algae wafers are a great snack for goldies 🙂 I think Hikari makes them, you can find them on Amazon. As far as the salt in there, no, that’s not a good idea to have it in there all the time. It will stress the immune system of the fish. The garlic is good though. Gel food is a good option.
Thank You, Pure Goldfish. Your always so helpful. So was that a no for the brown marine algae then? Because my friand has a salt water tank and has a big bag of the brown marine algae, she said I could have some if it was any good to feed my fish with. In regards to the garlic, how much should you give the fish? An how should you prepare it to give to your fish? Thanks again for all your help. Kim
Actually I think the brown marine algae might work, goldfish can eat marine based proteins so it probably would only help them. Try it slowly and see how it goes. As far as garlic goes, I think you want to steam that and chop it up into little pieces.
My gold fish have always been active but recently after hailstone storm in summer they are sat at the bottom of the pool sometimes hiding under rocks and listless
Did you try testing the water? If there were loud noises during the hail storm it may have frightened them…
Hello Pure Goldfish,
Today I brought a new fish from a market!
It’s a goldfish I’m pretty sure, it’s colours are a mix of white, black and silver and it’s fins are clear/translucent. So by being curious I was watching my fish and I notice that on his right side his two bottom find had gone and what remains are the bone, or a short stumpy thing. I’m not sure if it was a disease or the other fish had eaten it off?! Also when I put him in the tank he had a swim around a plant I put in then he swam to a spot right in front of the glass where I was watching him and he just stayed there for a few hours then I fed him and he ate, slowly the he swam to the exact same spot and stayed there. I did my own thing and came back he then swam around the glass and moved back to the other spit and started Sinking and sat on the pebbles. So a few hours later/now he swam around when I came back and moved to a different spot and he is now floating in the middle of the water…
I do not know if it was just him adjusting or if he is sick? He also comes to the top but doesn’t go out of the water and he opens his mouth just barely touching the surface. I have noticed when he swims he goes slowly because of his no finned fins and under his gills it is bright red!
I do not know what to do the water is fresh i left it out and got him to adjust to it and let him be. He is a tiny bit more active but I do not know what to do?!
Please help xx
Red gills are actually healthy gills, so no worries there. But the missing fins, that could be eaten off by another fish or disease or even just genetic. It’s hard to know for sure. Just keep the water clean and keep observing his behavior, if it happened recently he is probably pretty stressed.
Also should I feed it peas if it is sick? I am giving him regular fresh water/goldfish flakes
Peas won’t help the fins but they are a good snack. 🙂
Thanks Pure Goldfish !!
That helped so much ???
Since yesterday Bruno is much more active but since he has no fins on the right side he is a bit slower but now he swims around the tank and it is so cute whenever I come to my room and he sees me he swims around the front of the tank like he is excited?
One of his fins has a little bit of growth but otherwise I’m pretty sure he was just stressed!
THANKYOU SOOO MUCH ??
Aww fantastic to hear Jess <3 Glad Bruno is doing better 😀
Also I just fed Bruno and he got really scared when I dropped the flakes on which he never got scared of before!? How do I make him not scared anymore
It will probably take time for him to get used to you. Once he figures out you are the food source, it’s all uphill from there 🙂
i’ve a couple of goldfish. their fins turns to red colour, loose his scale from time to time. i love them so much. please help me ?
Could be high nitrites, did you test the water? It is hard indeed to see them suffer 🙁
I have three comet’s that are recovering from a bad tank. Too much nitrates, and hard metals. There tails have broken blood vessels and are slightly torn. I added baking soda, and salt to the tank. But how do I go about putting the hydrogen peroxide on their tails? They are quite large and hard to hold on to.
Don’t use peroxide on their tails, it won’t do anything for that and will only stress them out. Clean water and the issue will heal itself.
Thank You, Pure Goldfish. t6hat is good to know. I have other fish other than a gold fish in the tank though i have tetra’s and guppies, and mino’s an a coridora, and a shark as well as others. will the brown marine algae be ok, for them as well? Also I noted that some said you can give peas to your fish too as a treat. due you cook them too? what other every day foods can you feed to your fresh water fish? as always thanks for all the help. kim
Not sure about the other fish’s dietary requirements, you don’t have to cook the peas, just dethaw them and shell them and chop them up a bit.
Hi Pure Goldfish, i hv 5 goldfish in 4×6 feet aquarium. one of them seems have cloudy eyes. What should i do to overcome this issue. Should i change 100% water inside, replace new water and put some salt as suggested. Thanks in advanced. 🙂
I would change the water but skip the salt because you don’t know if its parasites.
Hi there, I have a black moor and a red and white ryukin in an indoor pond in my room. The pond is cycled and water changes are done regularly. My black moor came with a bit of a dent in his gills. It almost looks like the flap that’s covers the gills was somehow cut and now the gills are exposed. He doesn’t act sick at all but the area is slightly orange. Is there anything I should be doing about this (salt baths, peroxide swab, etc.)? Thank you in advance, I love your blog!
Could be an injury, but it isn’t anything you can help. Some goldfish live with missing or damaged gill covers all their lives. Glad you like the blog 🙂
I have a 9 inch beautiful white lion head . Over the last few days she has been sitting at the bottom of the tank. Yesterday I noticed she was getting a deep purplish color and swollen on on one side of her head. Today i took her out of the tank and put her in the hospital tank treated with erythromycin because she is really swollen and has a sore on her mouth. Very worried and help would be great
Sounds like a bacterial infection. Have you tested the water yet for ammonia, nitrite, nitrate and pH?
I have a comet in the backyard pond. 3 weeks ago I saw his 2 side fins have some growth (pinkish); I catch and keep it in the 20 gallon bucket with the running air stone.
How can I treat it?
Thanks,
Todd
Not sure exactly what that is without a photo, but it may be carp pox. That is seen in ponds sometimes.
Hello, in March I bought a 4litre aquarium with two common goldfishes, Sam and Ernie. A month ago I bought a 15litre tank and I added to the family two more fishes, a shubunkin goldfish and a a calico goldfish. All of them loved the tank. One morning, a few days ago I saw that Ernie wasnt doing so well, he died that day. Now Sam is behaving weird. He doesnt want to swim, sometimes it just stays in the bottom of the tank for a few. It eats 1/4 of what it used to. Right now I took Sam to the 4litre aquarium and I dont know what to do. Loosing Ernie was painful, I dont want to lose Sam as well. Please help.
Sorry to hear about Ernie 🙁 To save Sam and the others you will need to change all their water daily, don’t feed and get a bigger tank as soon as you can because they produce too much ammonia to live in it without water changes for very long.
Sam is not swimming anymore and its on one side. I changed the water, the other fishes look ok. I didnt feed them. I donnu what to do. 🙁
It may be the kindest thing to euthanize at this point… :'(
Hi,
My fish is named derp 3 days ago it stared looking sick so
I looked at diseases and figured derp has fungus yesterday it stared
Staying in a house and today he’s up near the filter please help!???
Hi Aubrey! Have you tested the water? What size tank is it?
Hi, my goldfish has a pimple like lump in her mouth and it seems as though she can’t close it,
She won’t swim very far off the bottom of the tank but still trys to eat.
The tank is always kept clean and in good condition, there are two other goldfish in the tank and it is about 107 gallons
PLEASE HELP!!!!
It’s hard to know without photos… you might try sending me some on our Facebook page, http://www.facebook.com/puregoldfishdotcom.
Thank you for your reply, I have sent some photos in a facebook message.
Pure Goldfish! I need help, all of a sudden my Bruno was coming to the top of the tank to breathe so I Quickly changed the water and put everything back, ever since this Bruno is now sitting on the bottom not moving unless I tap the tank or give him food. It’s very weird I have changed his water about 5 or more times now and this is the first time he had acted weird?! Also he has formed a bloody/reddy area underneath his mouth and he was fine when this happened but after I changed his water he is going weird. Also he has flattened all his find (If you need pictures I don’t have Facebook so?)
THANKS Jess ❤️
Have you tried testing the water yet? It sounds like something isn’t right… you may want to see if your tap has ammonia in it too.
my 2 yellow fish are growing green algae on their backs, how to i fix it?
Hmm, fish move around too much for algae to grow on them, it might be helpful to see some photos. You could post them in the forums or on our FB page, http://www.facebook.com/puregoldfishdotcom.
I have a fish that has a black little ball on the top of its head on the front edge of the fin
May be a tumor. They can be black.
Hi, a few weeks ago I moved far. I had brought my gold fish with now 1 of them seems to be sick, symptoms seem to be colour change, weight loss, no move ments (other than breathing), won’t eat, and toting fins. What do I do. Please help
Can you provide some more details about your setup, Ethan, such as the size of the tank, number of fish, water change schedule etc.? If you started all over when you moved and didn’t keep your old filter media it could be causing New Tank Syndrome…
Hi, so sort of having a panicking attack right now. I won one goldfish at the fair yesterday and today I went to buy a better tank for him and some supplies and what ended up happening was I bought a 10 gallon tank, filter, water conditioner, nitrifying bacteria starter, and two more goldfish. Right when I came home I set up my fish tank and added the fish right away and left around 5pm because I had a day planned out with my friends. My parents were left at home to watch them and noticed my black fish was sitting at the bottom of the tank and sometimes swimming around and went back to the bottom. My parents went to the pet store to figure out what was going on and the lady that helped us earlier only said the fish is stressed and didnt really help. My parents ended up not doing anything to help and I just got home around midnight and I noticed my black fish is peeling and laying down still moving occasionally… My other two goldfish occasionally goes to the top of the tank to get some air.. and i noticed theres tiny fuzzy balls in the bottom all over the tank. I know all of this is terrible because at the moment i’ve been searching through so many websites to figure out what is going on and what can I do..my fish are suffering and I’m worried they wont make it through the night… Please help me
Sounds like New Tank Syndrome. The tank is overcrowded too, adding to the waste load and causing the water to become very high in ammonia. Daily water changes until you can get a larger tank and until the filter is established, which will take 3-4 weeks. 🙂
Today I was looking at my fish and I noticed black dots in my oranda’s mouth. Is this normal??? If it isn’t please help because he is my favorite and I have had him for 3 years
Also, I forgot to mention this but the spots are only visible when his mouth is open because they are literally in his mouth
Could be just pigmentation, but check the ammonia levels…
Just the other day I noticed that my fish had a black dot on his tail fin. It seems to be eating away at his tail since his tail is ripped around the same area. Any advice would be greatly appreciated.
Hi Jordan, did you test the water?
No, actually I didn’t. I don’t even own anything to test my water with
You can usually get it tested free at your LFS. It can provide some helpful insight.
I found my goldfish on the worktop, he must have flipped himself out of the tank somehow. I don’t know how long he had been there but his scales were dry and he looked dead. I went to dispose of him but he showed signs of life by gasping for breath so I gently put him back in the water. To my astonishment he slowly recovered but remained on the bottom of the tank for several days. He then developed a cotton wool slimy substance on his side that had been in contact with the work top so I have been changing most of the water and putting sea salt in. The slimy stuff is reducing but he has now got black areas where I think he is healing. He seems to be recovering well otherwise and he has started feeding again. His mate and companion of ten years is constantly by his side and is healthy so I think the water and tank condition is good. Is there anything else I should do for him?
You are doing the right thing, keep up the clean water and keep him calm. 🙂
My sister’s goldfish has a pebble in his mouth. She’s says it’s been there for quite a while and it doesn’t seem to be bothering him too much. If you have any ideas on how to get it out would be very useful.
This probably will require manual extraction pushing the bottom of the fish’s mouth to open it and then pulling it out with tweezers.
My goldfish seems to be sick. Today I found him at the bottom of the tank behind a boulder. I’ve heard before that fish do sleep but I have never caught him in this position before and I’ve had him for three years. After I managed to ruse him to movement with some food I noticed he was unusually clumsy. Running into other goldfish in my tank, into the walls, and even into the filter, though he was perfectly capable of swimming away. He’s not doing this anymore so I assume he might have just been waking up but I can’t be sure. He seems to be staying at the top in a vertical position with his mouth to the top taking in air. I don’t believe its swim bladder because he has no problem swimming to the bottom again but the possibility is still there since he does seem to lean on one side slightly even when swimming. However, about two weeks ago I did notice black dots speckling his mouth area which are only visible when his lips are stretch outward when eating or inhaling bubbles. I cleaned the tank but that doesn’t seem to make a difference. Im wondering if this might be a cause from my spong cover for my filter because I got it shortly before the problem occurred. Since the fibres of the sponge don’t really absorb all the waste and access food very ephishiantly I have noticed that my fish make it their duty after feeding time is over to go over to the sponge and peck at it for for more food. I have also noticed that this particular fish does this most often and that algee has begun to form on the glass behind the filter. I’m not exactly sure what size my tank is but it is definitely either a forty or thirty gallon ( most likely thirty). I have four goldfish. This fish is an oranda and my biggest goldfish. I know him like the back of my hand and I know when my goldfish is in trouble. Please help, any input would be GREATLY appreciated.
I need some advice regarding my telescope eye goldfish. I’ve only had him for a couple months but the little guy has been through a lot with me, this is the first time as an adult I’ve had fish and so of course I made all the classic first time goldfish keeping mistakes. He started out in a uncycled 5 gallon tank with another telescope eye and they both came down with ich. I moved them to an uncycled 38 gallon (at that point I didn’t have many options other than going back in time and doing my own research rather than trusting the guy at the pet store so I figured if they had to be in an uncycled tank at least they could be in one big enough for them). And then I treated the ich with heat, the original tank mate unfortunately died within a day of the move to the big tank but little Fruti made it through and has been ich free for about two months now. In the past week or so he has started to lose almost all his orange coloring (he was originally white and orange). I have a HOB filter and the water parameters are: pH: 7.8, ammonia: 0 ppm, nitrite: 0ppm and nitrate: somewhere between 0 to 5 ppm, temp is 73 F and there is a large bubble stone in the tank. His only companions are several Japanese trapdoor snails and some live plants. Today I noticed some small (2-3mm) lines on his fins that appear whiter than the surrounding areas. Having experienced ich before it definitely doesn’t look the same. He is still acting normal and eating, should I be concerned? Have you ever seen something like this? We have a black moor in quarantine right now (came down with ich a day after coming home, proof it is ALWAYS necessary to quarantine new fish). The black moor will be ich free for two weeks this Friday and I was planning on introducing him to the 38 gallon tank but I don’t want to do it if Fruti might be sick? I’m definitely attached to this little guy (way more than I ever thought I would be to a fish) and not sure what I should do…
The lines on the fins could be breeding tubercles… You will need to treat the other fish for ich before adding him in with the other.
Hi, we have 2 goldfish in a 2.5 gallon tank. We’ve had them for years and they seem pretty happy. We have well water and I always treat with aquarium salt and a water treatment solution when I clean them. It went a little too long recently, and the older fish (he has to be at least 6 years old – I’ve lost count) just developed some red spots on his fin and his body. I immediately cleaned the tank, but I’m worried about him. I saw you said to clean the tank and put in salt (done and done) but you also suggested hydrogen peroxide. How the heck to you put peroxide on a fish? That’s the only thing I haven’t done. His buddy in the tank doesn’t seem phased at all, and I hate to separate them- they’ve been together for years and I really think it might stress them to be separated (you may think I’m nuts, but I do think they enjoy each other’s company – they swim to gather like a tiny school 🙂 ). Anyway if you can suggest a way to put peroxide on my red spotted old guy, I’d be so happy. Thanks!
I wouldn’t do peroxide in this case, as that is more for parasites/infection. These are basically blisters. I would recommend first off getting them a larger tank, at least 20 gallons if they are fancies, as it will greatly increase the chance of recovery by providing the most clean water.
Over the past day I have noticed more clumsiness and he continues to go to the top more than usually for air. He seems really stressed out. Please respond quickly!
Earlier today I even saw him do a face plant into the gravel!!!!!!!!!!!!
Oh my God!!! You NEED to help my as quick as possible! I just went to check up on him and I couldn’t find him!!!!!!!!! After doing a thorough check I found him in the cave he was behind earlier in my previous note. I don’t think I’ve ever seen him go in there, maybe only when he was a baby. He wasn’t moving and before I moved around the cave a little bit, I wasn’t even sure he was still breathing!!!!!! I’ve been sitting here for about five minutes and he has yet to come out. He looks to be in a very cramped and uncomfortable position with his face in the gravel and the rest of his body bent off to one side. I tried to get him to move into a less alarming position but he just readjusts himself back again. He didn’t even come out for food!!!!! PLEASE HELP ME!!!!! I don’t know what I’d do if he died. He is the only remaining goldfish from the first couple I ever got, I’ve had him for three years and he is the pack leader to all my other goldfish. I don’t know what they would do without him either. Should I move him to a secluded 20 gallon? It doesn’t have a filter so I’m not sure. Is he going to die!!?!?!?! PLEASE RESPOND AS SOON AS YOU SEE THIS!!!!!!!!!!
I decided to move him to my 20 gallon. He’s moving around, but is staying at the bottom and occasionally leaning to one side with his tail. Please get back to me, I could really use you professional input.
Have you tested the water yet? How many fish are in the tank, and any gravel? How often are you changing the water and how much?
There are 4 goldfish including this one and yes I do have gravel. I just recently changed 100% of the tank water about a week and a half ago and I am going to get a water tester today.
Let me know how it reads 🙂
0 ammonia, 0 nitrate, and 0 nitrite. I’m hoping that has something to do with me removing the sponge cover to the filter yesterday and that he was just acting up because it wasn’t circulating the water correctly but it might not be. After discovered this I was confident in my plan to let him into my main tank and hopefully he would be ok. He didn’t put up a fight at all when I collected him and once I put him in he just kinda leaned to one side barely moving. I didn’t wait to see how he would act if I let the cleaner water enter his system. I just panicked and put him back in the individual tank. im thinking about taking all my other fish and putting them into the 20 gallon tank for about a half an hour to let the sick fish readjust himself and hopefully recover. Do you think his sickness has to do with the water, or do you think it’s something more serious? Please get back to me soon because I don’t think I can wait another day for a response!!!!
I would only put him by himself if he is getting picked on, but it could be there is a problem in the main tank. If he is on his side it may be too late…
PH 6 to 6.5 amonia 0 to.25 to .5 nitrate 0.0 nitrite 0.0 no gravel ever plastic plants. 25 gl hospital tank filteration stres zymes and amonia nitrite & nitrate treatment. aquarium salt..

Im so stressed out on what am I doing wrong I even sanitized my room with a germicidal disposable wipe super sani clothe use different nets for the two tanks. this new female fancy with the fin rot is so beautiful shes black and gold with beatt eyes. we need your badly. you helped along time ago ISurfed the net and found you again. your the best Pure Goldfish please help me get us through this disaster to ease our stress thanks presh.
in case you didnt see my question in all that rambling. How long do you keep your fancy’s in aquarium salt for treatment. I read spmewhere that gold fish cant live long in saltwater because they are freshwater fish. so diluted 10gl so I dont od my fish. at this point im lost about to give up negligence killed my two best fish. she was ready to lay her eggs. I feel so bad! sad! please let me know if im missing something and the ratio of salt to gl for treament and how long do you leave them in before you change the water. thank you.
The water quality is your issue, with that low of pH and ammonia you can’t do any kind of treatment. You will need to be changing the water, I wouldn’t salt.
Hi Pure Goldfish my apology for long question/post I dont overfeed and feed them seaweed romain lettue I lost track of how much salt and how long do I keep my fancys in salt treated water ? for fin rot please help me asap I dont know where else to turn. im getting very stressed now all 3 have fin rott I took them into my palm and used a Qtip for peroxide and dumped a 8 oz bag of aquarim in the 25gl tank one of them are swimming on its side. its not looking to good. please please reply I feel Im running out of time.
wow I read every post on this page. its really great to see someone who cares & helps everybody! Im hoping, praying my new babies make it through the night.
Hi Pure Goldfish, my fish made it through night. the initial fish that was on her side is now swimming normal . the other two fancies, came down with fin rot so I zapped them in the salt bath. I did not see your reply until just now. so should I change the water 100% 75% 50%25%? no more salt? no treatment? what can I do for this fin rot? should I put more ph up? the instruction read .25 ppm for a 40 gl tank I put in .40 doesnt do anything how the heck can I get my water ideal so my my poor fish arent suffering. I wasnt clear on your response yesterday.
100% is always better. No more treatment, what they need is lots of water changes. Daily until things are under control. Hope that makes sense 🙂
Thank you for the sound advice 90% of us have water issues because we weren’t ready for this responsibility. thank you for helping me realize what I need to do to be a good responsible pet owner, keep a clean tank. simply changing the water maybe the answer 90% ofthe time. My buddies fins have stopped disintegrating & are swimmingly happy, lovingly devine. They asked me to please say thank you & God Bless you Pure Goldfish! (Religious fish) haha ⓒ;?}~
Glad to hear it Precious! Recovery is always such a relief when it comes. Keep up the good work 🙂
I have a pond with goldfish. We have a filter and a couple of bubblers. There are plants growing in the water.
One of my goldfish has a big lump. It looks like it is inside it’s body not on it’s skin. It is like a marble or a big pea. It came up very quickly I think. Do you think it’s an internal tumor? Can I do anything for it? Should I separate it from my other fish? One of the others has maybe , the start of a lump- a small bump, and I don’t know if this is the same thing starting. I have considered putting both in another small pond where I could medicate them or add salt if needed.
Also if I add salt to the water, wont it kill my plants? The plants are essential as the larger pond is only 30cm( 1 foot) deep to meet local council laws. The smaller pond is deeper, but the plant in there can be replaced easily if it dies from salt.
Thanks for your help, your advice is really helpful.
It does sound like a tumor, though it would be hard to tell for sure without photos… sadly medications and salt are not effective treatments for them, as they are basically cancer. :/ We do detail the most effective tumor treatment plan (besides surgery done by a vet) in our book, which I think you would find useful. Hope this helps 🙂
Thanks Pure Goldfish. If the fish is still active and eating, should I take it as a sign that it isn’t suffering?
What do recommend as the kindest way to euthenize a fish, when the time comes?
I definitely think I need your book.
Hi Leigh-Ann 🙂 Thanks for picking up your copy! I recommend freezing as the kindest way to euthanize, as outlined on page 92, though if the fish is active and eating it may have a good chance to make it. Let me know if you have any further questions!
Hi! So my little fish is going through some problems I think might mainly be stress. Not to long ago, his partner passed away. The levels of the fish tank are normal. The tank is 2 gallons. He has an cloudy eye but it starting to clear up after a Justin the pH. Anything else you recommend to help clear it up? Also he has black spots on him that weren’t there before. He developed them once before but not as bad as now. He isn’t as active as he used to be. Any suggestions on what is wrong with my goldfish??? I got him only a few months ago.
Please get back to me if you can. I really like and enjoy my fish and I also have a quick question. Do you think I can get tetra fish in that tank or is it too small? I do not mean with any other fish. Just curious if you think I could. By the way, the fish tank does have a filter but doesn’t work as well as I’d like it to so I change the water weekly.
I think it has pneumonia. How do I cure it? The levels recently got really high, but that was about a month ago when my other fish got it. Can pneumonia be spread by other fish? What is going on? The levels have been fine for about a month now. I just checked. Will it die or can I do something for it???
Hey Luna! Your situation sounds a bit complex. I would recommend following the tank setup/stocking guidelines and water change guide for sick fish as laid out in our book, and definitely no tetra fish or any other fish in there as they are not compatible with goldfish. Hope this helps! 🙂
Okie thanks! Sorry I meant tetra alone in another tank the same size. Sorry it is complex. I don’t think the little guy will make it. I just, I mean he’s all alone in the tank and I’ve been trying everything to cure him. The same exact thing had happened to my other goldfish that was in there with him a while back before it died. I set the tank up right and stuff. I just think it’s odd that he caught pneumonia when the levels are fine. Odd thing about my fish tank, the water seems to evaporate pretty fast.
And one other thing, I meant ammonia not pneumonia. It kept auto correcting me sorry.
Hi there, I’m desperate for some advice, my goldfish cant open his mouth and I’m worried he’s going to starve to death. I have contact local fish shops and been given medication for fungal and bacterial infections. It looks swollen and did have a bit of white around it but that seems to have gone now. No one at the fish shop had ever heard of it. I’m so worried about him
Hi Lyndsay! What you are describing sounds like mouth rot, which comes with a variety of symptoms surrounding the mouth opening. I would recommend following the emergency treatment plan for this as outlined in our book The Truth About Goldfish. You’ll also get access to our premium goldfish support system with a personalized plan for your situation. I would encourage you to check it out! Hope this helps 🙂
That’s great thank you, I’ve also noticed tonight that my other gold fish has little red flecks in his fins so wondering if this is part of the same problem or something completely different? 🙂
Chances are, they are both being affected by the same thing, just showing it in different ways. 🙂
So sorry to bother you again but a vet has advised giving the fish an injection of baytril antibiotics, is this something you would advise? Many thanks 🙂
No, that will almost certainly seal his fate. I would recommend the treatment plan in our book – much safer and effective.
Hi, Im kind of freaking out here! I have five common goldfish I won at a fair, two of which I believe to be twin brother and sister (I named them Dipper and Mabel.) Everything was fine until just a few hours ago when Mabel quit swimming and began to act dead. Shes still breathing just fine, but Im not sure whats wrong! I have all five in a 15 gallon storage container with a filter, only until I can find an actual tank for them to inhabit. She was perfectly fine until ust a few hours ago, and Im not sure what to do! I love my fish dearly – theyre my first actual pet, and I wouldnt want any of them to die! I especially dont want Dipper to be without his sister – Ive noticed those two play together more than any of the others. Please, is there any possible way to save Mabel?! Please get back to me soon!!!
Hey Anna! 🙂 There are a lot of factors that play into when a goldfish suddenly gets sick like that, so without knowing all the details its hard to say for sure. Either way I would recommend following the emergency care plan as outlined in our book, which I would encourage you to have a look at. Hope this helps 🙂
A few days ago I did my usual water change and clean. The next day I noticed the two goldfish had eaten one of the smaller fish (They had previously left it alone for months but it was totally missing from the tank) A few days later on of the fish has developed a lump that looks slightly oblong and internal. It does seem to have gotten slightly larger but does not seem to be stressing it out at all – eating, swimming normally. The other fish is fine. They are about 18 months old. My son is a bit distraught and wants to know if it will kill his fish.
Hi Sandy! It sounds like the beginnings of a tumor to me. I would recommend following the tumor treatment plan in our book to prevent it from getting out of hand (which can kill the fish). Hope this helps 🙂
Hi,
My oranda gold fish is supine in the bottom about few days ago. When I taping on the glass of fish tank, she will suddenly swiming here and there. Not eating, but I treaded for swing bladder treatment too. Still still not cure.Still sleeping. I changed water also. Pls adv what is this deasease.tkx.
How much of the water did you change?
Hello,
I have 2 oranda gold fish. I just changed the water 3 days ago, like 50%. Today I saw one of my gold fish has a lump on his body. He is still eating, and playing around like usual. He seems really fine and healthy, but I dont want his sickness get worse. Is there anyway I can treat him? I dont know for sure if it a tumor or he has an ulcer. Please help. Thank you.
Rosalie.
p.s: I took a water test by master kit. everything is fine, pH is around 7.0, nitrate and nitrite is 0. Amonia is 0.25 ppm or 0.5 ppm I cant really tell.
Hi Rosalie! If you have traceable ammonia, that is likely what is causing the problem. A lump is likely not an ulcer but a tumor, though without seeing it is not easy to say for certain. Either way, you will need to get that ammonia down right away. I’d recommend following the emergency treatment plan found in our book to get those levels to 0 as well as assist in healing the problem. Hope this helps! 🙂
I think my Black Moor has a big tumor growing behind its dorsal fin. The fish has been acting very normal and active and eating well, just a scary bump on its back. Please help. I don’t know what to do, I don’t have the money to take it to a vet. 🙁
Hey Kimmy! Surgery is a common route for tumors, but what most people don’t know is that it is not the only option. We detail a tumor treatment & prevention plan in our book (which is much more affordable than a veterinary bill!). It’s really important to take action right away to stop its progress. Hope this helps 🙂
Hi there, so my fish has this cloudiness over its eye and something hanging from it. It’s not quite “White Eye” but I think it may have “Anchor Worm” (hopefully I said that) But I’m very concerned. I just bought him two days ago and since I didn’t have an aquarium (I thought I did before I brought them home) I put him in a bowl for a day. (I bought two other fish, a smaller version of him) Please write back when you can. If you want to email me and want me to send a picture, I would so much appreciate it. I’m so concerned.
Most likely that isn’t anchor worm if it is on the eyes, as anchor worm is more on the head and body. Likely it is mucus trailing from the eye which is being burned. If your fish is still in the bowl you will need to take steps right away to correct his conditions so his eyes do not become infected. I’d highly recommend checking out our book for detailed advice on the matter, as it also gives you one-on-one access to premium support here 🙂 Hope this helps!
Hi,
So on the heads of my three fish, I can see red veins/ lines showing on the top of their heads. I just got them about three weeks ago and put them in a tank. Are the red lines normal, or is it something I should treat? Thanks!
Sometimes they can be normal, other times it is a problem. Depends on the fish’s coloration… on white/clearish fish veins show through easier.
I had 5 goldfish in my garden pond. However, they are dying rather quickly. One of my pure golden coloured fish has died this morning and another one that is silver with orange patches on it has died at about 3pm, and I’m worried about the others. So is there anything I can do to stop them from drowning or dying? There’s a black fish, a golden fish, and a silver coloured fish. They don’t show up very often, but the pond that they’re in has a lot of plant roots because there are a lot of plants in the pond. Also, the water seems very dirty. I don’t want to take the other goldfish out to clean the water because they might die of shock… Any ideas on how to help them?
Oh my goodness! Please reply quickly! Another one has died, now there’s only a black coloured goldfish and a silver coloured goldfish! I really need help on what to do to help them.
Hey Ayana! Sorry to hear your fish are dying so quickly. It sounds like you really need to follow the emergency protocol outlined in our book for correcting the environmental conditions that are poisoning your fish.
My fish has two large lumps on the side of its body. Covered in scales what can I do
Sounds like a tumor, or the beginnings of one. I would recommend following the tumor treatment plan as outlined in our book, The Truth About Goldfish.
Hi
I had a Ranchu guppy that I got last Thursday. Three days ago I woke up and fed him and he was absolutely fine. But when I checked on him later, he was developing red gills…one side was worse than the other and the worst side had three little lumps. The next day it got worse and his bum became red and on his back. He still was swimming and eating fine. We couldn’t find any answers but took him out of the tank into a fish bowel and treated him with a recommended product and salt water…he died within two days after losing appetite. some of the red spots had white stuff growing from it.
Do you know what kind of disease it was?
Thanks
Likely has to do with NTS (new tank syndrome). Most people don’t cycle first.
Hi Pure Goldfish, I posted on the 28th July to which you very kindly replied. This is an update on my goldfish – he is doing just fine! He lost all scales on the side where he had been in contact with the worktop when he flipped out of the tank. Within a few days he developed a slimy substance covering the area and turned almost black over most of his body on the unaffected side. I kept changing the water and adding salt and was able to very gently wipe the slime away with a cotton bud. I was a little worried when there was some blood on areas I didn’t touch! He has slowly but surely made a miraculous recovery! The black discoloration has completely disappeared and is developing what looks like new scales. He is happily swimming around the tank with his mate and swims towards me when I’m near the tank! I swear he knows his life has been saved. I call him Jesus because he is definitely resurected! He doesn’t know how lucky he was not to be flushed away! The Moral of the story is ‘Never give up on a sick Goldfish!’
PS. He now has a more secure lid on the tank! I am grateful to this site for the information you provide. Thank you!
Wow, that’s great to hear! Good job nursing him back to health.
Today I noticed that the base of my goldfishs’ tail is swollen, red, and has some white on it. This coloration moves about halfway onto the tail fin. The white that I see isn’t something on the fish, but it looks more like a discoloration. It looks painful as well. The reason why I noticed it is because I saw him resting on the bottom which I thought was odd. That is what prodded me to have a closer look. I tested the water and all the chemical levels and pH are fine. My water isn’t cloudy, however in the posts I’ve read it sounds like high levels of ammonia is the culprit. Any insight on the problem for me?
High ammonia would definitely cause those symptoms. Not sure if you tested for it…
We change and prep the water regularly in our ten-gallon tank (no algae on the glass; the gravel is vacuumed), but our fishes keep on getting sick: One died about a month ago. The four others were just fine until this week, when one developed a sore (a scale fell off; then left a red “dot”). Another one now has three bumps similar to the tumors your site mentions above. Are they contaminating each other? Can we add salt to the water as you mentioned? We feel helpless.
Thank you for your site: It’s very informative!
Contaminating each other… could be but more than likely they are all being affected by the same thing. Salt is not a cure-all by any means and can only be used after following the emergency care plan outlined in our book. It also includes a fail-proof tank setup guide to optimize your fish’s living conditions. Glad you like the site! 🙂
My goldfish is sinking at the bottom of the tank and does not want to eat also it’s acting weird and I have had it for a month now and today it’s acting like this it’s never acted like this at all is it sick or hurt?
Bottom sitting is definitely a symptom that something isn’t right. Means that the fish isn’t feeling well in most cases.
This morning my fish had been at the bottom of the fish tank (still alive), but barely moving only going around the bottom of the tank. It looked like one of his gills had something greyish white, and he seemed not able to balance. It’s pretty late at night, and he still hasn’t really moved. I heard that it could be a tumor, but it isn’t a lump of anything and almost looks fuzzy. It has also grown since this morning. What’s wrong with him.
Doesn’t sound like a tumor… I’d recommend checking out our book for the correction plan it contains.
My goldfish seems to have very mildly red tiny bits on its body, it has had these for quite a while so I just suggested they were minor injuries (Some have healed), I haven’t fed him to much lately cause I was changing the water but his stomach did appear to get slightly skinnier, is this flukes? And if it isnt should I put that flukes fighting chemical in the tank?
Doesn’t sound like flukes. Wasting is usually caused by an internal bacterial infection. I would recommend the emergency care plan found in our book.
Hi, I have 6 outside goldfish in a pond, the other day I noticed that 3 of the fish were chasing one and kind of ganging up on it. Because its Spring here, I thought that it was what fish did at this time of year. But, a few days later noticed that they were getting even more aggressive and that most of the scales were gone on one side of its body, the fish was floundering, and lying on its side, and looking very stressed. I have separated the fish to a small pond. Now it has what looks like a white cottonwool effect covering the area where the scales were. Hope you can help.
Probably the fish’s immune system was weakened by the stress of chasing, resulting in infection. You can follow the emergency care plan found in our book to nurse her back t health.
Hey your article was awesome
But by the way,i have a fantail that has the Dropsy: The Pine Cone Disease and (this is probably an annoying question considering the fact that you explained it,and i’m sorry for that just wanted to clarify)and i was wondering if he/she will make it?, i also had a comet that had it,but he has passed.
p.s how do you tell a male goldfish from a female?
It depends on how early you act and if you correct what caused it in the first place. Otherwise it will just come right back. Male vs. female… there are a lot of ways but males usually have breeding stars during breeding season.
My goldfish is on the bottom of the tank, sort of twisted but still alive. He’s been there all night. He has a growth on his eye which has been getting bigger for some time. He is abou 14 years old – is there anything I can do for him?
It may be time to put him down 🙁
The Left Eye of my Bubble-Eye Goldfish is inside its Sac, and it is kinda white (Or maybe just because of his eye, I don’t know)… Is it normal to have the eye inside the sac? Will the eye go outside from the sac. Please help me. I feel so worried.
Hard to tell without photos, but the bubbles just may be bulging over the eye normally for the breed.
I can send the photos. I just need your email, if you could only give me… It just bothers and worries me a lot… ? Thank You for the reply. I appreciate it.
You can post a topic in the forum and upload attachments there.
My fish has two big white spots. And what i mean by spots is massive warty things that are next to his eye. We really dont know what it is and if there is a treatment. I would appreciate if you could reply.
Those are usually tumors, but it could also be the lymphocystis virus. I’d follow the emergency care plan (that covers both tumors and viruses) in our book. 🙂
It looks as if my gold fish has “fin rot ” if there a faster way I can heal it
Many factors contribute to healing, but the first is to correct what caused the rot in the first place. Then it is only a matter of time.
One of my goldfish has had a small black spot on her head for some time now. It has not grown at all and is not causing any discomfort. It is not protruding either. If it is a pigment change, how likely is this, when it is more likely that goldfish are more likely to turn paler with age? She is over 13 years old and in good active health in a well-maintained three foot aquarium. Your comments would be very much appreciated, thanks.
Pigment change to black is rare, but it does happen.
It like his fin are shrinking and he is not as active as he used to be it started a only yesterday and he was sleeping belly up but when I got near the tank he started swimming so I’m at a loss please tell me what may be wrong
Shrinking fins could be an indication of caustic burning. Accompanied by other signs that is likely the case.
I recently bought two new goldfish. I have them in a temporary holding tank until my quarantine tank is vacant. (It’s been about a week). One is red and white, the other is orange with black spots. My red and white has started developing black spots. How do I distinguish normal color change from disease?
Changing to black is rare, and usually indicates burning.
My goldfish has one white kinda fuzzy looking spot on his head right above his lip in between his eyes. Maybe it’s ich?
Could be. But one isn’t enough to tell for sure in most cases.
My gold fish scales are dropped down what to do for it please rlp me
You mean, dropped off? That means the fish is scratching itself out of irritation…
Your infos really helped.
I have a bullhead goldfish that stays head downward in the corner as if playing dead. Do you think theres something wrong about it.
Yeah goldfish don’t play dead, usually a sign they aren’t feeling well.
Hello! My small (2-inch) goldfish is very sick. He was depressed a few weeks ago so we got him a friend — I thought he was lonely. We acclimated the new fish for a day and a half and then two days later it died. We changed the water and everything, but the old fish started getting really sick. He was light sensitive, not able to eat, his butt was floating some, and he had a faint shadow on his side. When I got home from work yesterday, he was floating side up at the top of the tank. I woke up him up (I think he was unconscious) and tried feeding him a pea, but he wouldn’t eat it. Then I put him in an epsom salt bath for 12 minutes. He perked up a little but he was still too weak to really swim. He kept getting battered by the current his filter was making, so I turned it off and check on him every three hours all night and oxygenated his tank.
I haven’t found anything that lists these symptoms and I’m so worried about my fish. Please help me. Anything at all would be so appreciated. Thanks in advance.
It probably started before you ever got the new fish. Goldfish don’t get depressed like people do when they are lonely, they get depressed when they are feeling bad. The new fish probably tipped things over the edge by throwing the system out of whack. I’m not sure about your setup, but chances are something isn’t right and its catching up with him. Our book details proper setup and common pitfalls. I would recommend taking a look at it, as it also comes with one-on-one support so I can coach you through the situation.
I have 3 goldfish for around 2 years now and suddenly I saw one of my goldfish has swollen up and I search it on the net to know that it is dropsy and I know that I can’t do anything now and it kind of sucks bcz I really take care of my fish well…I need to know what can I do.Is euthanasia is the last option???…I don’t know how I’m going to do this
Dropsy is usually fatal but there is a chance the fish can survive, if you follow our emergency care plan in our book.
Hello, I have a goldfish that is about two and a half years old. For almost a year now it has been swimming (when it moves) on its side in the bottom of the tank. I read up and have been giving it peas to help with digestion and not feeding him as often.Today while cleaning the tank I discovered a rather large almost transparent mass on its head, any ideas?
Sounds like a tumor to me.
I have a red comet fish and only realized the next morning he/she had a white dot. It was not flat but was a bump. It is only one bump and haven’t separated my tank with my othe six fish. Is it okay to keep it in there?
BTW A long time ago my other golden comet fish had ich and it grew worse, he/she even changed color into brown! We separated him/her and it was better by the brown all gone off his face , but STILL has ich on its tail until now.
Could it have affect my other fish????
Plz help
Ich usually drops off after a while, if the dot is still there it may be a tumor.
My son picked out a goldfish with bug eyes last night from store. When we got home and put him in the tank one of the eyes is sunk in. He doesn’t think it was like that when he picked it out. Is it possible this is a stress reaction or is my 17 yr old son mistaken. Can we help him?
Hmm, posting photos in the forum may help 🙂
One of my goldfishes has a long, black string-like thing coming out of the place right in front of it’s tail. The other one looks fine. I thought it was a disease so I looked on the internet and I didn’t find anything. I only got the two fish today, I’m not experienced with fish and it’s really late at night so vets aren’t probably open, what should I do?
Sounds like anchor worm. Pet stores usually have them. Pull it off with tweezers is a good start.
Im really not sure what is going on.
I had a oranda that died through fin rot and fungus on rear. I moved my medium established muli coloured oranda to a larger tank and have made sure the water is perfect condition.
Before moving the oranda -spotty was resting on tge bottom corner. So when I moved her I made sure water was perfect.
Since then the spotty starting itching on the gravel and swimming erratically. I treated the tank to a goldfish health additive for bacterial anf parasites.
Spotty has since then stopped resting in the corner but now near the surface not much movement near the filter.
She is feeding well but when swimming her back end / tail seem realy jerky not smooth like she used to be. And now I have noticed tiny white spots on body and tail. And a coupleof her scales seem to be lifting like ythey are going to come off.
Please help.
Lifting up scales could be indicative of dropsy.
Hello, I just got a white calico ryukin goldfish yesterday. She seems healthy enough, however, it appears that the flesh underneath one of her gills is rather red. Should I be concerned?
No, that’s normal. 🙂
dont know what happened to my gold fish ,they started having tinny white spots on their pelvic and pectoral fins with a whitish like small cotton on forehead and eyes
Breeding tubercles maybe on the fins. Cotton is not normal.
I have a shubunkin in a 75 gallon aquarium. He is a deep orange/red and black. The past few days I have noticed that he looks Dull. It is not ich, and I am not sure if it is Velvet. It almost looks like his sides are “Dry”. Not shiny at all. He has not been scratching but has been lathargic periodically. I did have another Comet die of Dropsey last week and in hast I got another Shubunkin to keep him company. I did not quarantine the new fish. After reading, this is why I am leaning towards Velvet.
Velvet is tiny yellow dust. Is that what you see? Dull just means the fish is producing more slime than normal.
Hi
My cold water goldfish has been sick for about 6 weeks he is on /off lying on side at bottom of tank. His gills look abit red & his poo is stringy white.
What can I used to help him?
Iv tried Fish safe.
I’d recommend following the emergency care plan found in our book, Katie. It will tell you exactly what to do step by step.
My goldfish has a whitish patch on its side with Red marks around it, I’m concerned it may be a disease and my other fish may catch it! The red marks do look like they could be scratches perhaps from the artificial plants but I don’t want to take any risks, any idea what it could be? He’s eating and swimming about as normal.
Sounds like a fungal infection that may end up ulcerated.
my fish is sick and I’m not sure what disease it has,it has been hiding not eating much and lying at the bottom but also its tail is a bit bent and floppy can you please tell me if it has a disease and how i could treat it if possible.
If the fish isn’t wanting to eat, you shouldn’t feed. You should also follow the emergency treatment plan we detail in our book. It also comes with access to one-on-one goldfish support to nurse your fish back to health! 🙂
Hi our goldfish is 3 years old and has developed a 3/4 mm white lump on its body not sure what we can really do
I would recommend following the tumor treatment plan found in our book.
hello, my goldfish has white, peeling stuff around his face and has white stuff in his eyes. do you think it could be ich or fungus?
Extra mucus is probably what you are seeing, not ich or fungus.
My goldfish got black mark above head. His full head gone black
Probably burns, as the skin turns black after healing.
one of my fish has a strange blood-red area around its front fins, and he’s having some problems swimming. Can you please tell me what type of infection or disease it is and how to cure it?
There’s so many things that could be, I’d really suggest using the guide in our book to narrow it down.
Hi Please can you help me to save my gold fishes.
Actually they are live in a glass bowl. I have set them to oxygen also. in yesterday night I saw some changes on their body. They had become inactive and they tried to breath very hardly. and also they got some white transparent skin on their body and head. Then I changed their water and after that skin had removed quickly. Then they breathed easily and they ate food. But today morning they didnt eat. They look in poor health. Please could you give me an advice.
Hey Pubudini! Glass bowls aren’t suitable homes for goldfish. They require lots of space to have proper conditions to do well, otherwise their water gets dirty too quickly and poisons them.
My goldfish has a red spot on him and the other fish seems to nibble at his back fins? any clue
Fish sometimes pick on another fish that is doing poorly in order to “rid the tank” of sick ones.
one of my fish has a red eye as well as red on his fins. He is a silver goldfish. what can i do?? please help me!
Red is a sign of broken blood vessels. This usually means the system of the fish is stressed. Did you test the water?
I have an outside pond2 metres in diameter, with a pump and I have 11 Goldfish. I notice a couple of months ago 2 of the fish have developed lumps on their bodies. After inspection today their is anther one with early stages of a lump. I did read on line and I’m guessing they are tumors. The lumps appear to be white or pale different from the colour of their normal orange. They are eating and swimming around normal. Do I have some disorder in the pond that will slowly effect the other fish as well? The water in the pond is clear with the normal algae on the walls of the pond.. The pond is once a week being topped up with fresh garden tap water.
Being topped off isn’t enough for maintenance, so those conditions could very well could start affecting the other fish too.
So my goldfish had Popeye which I treated and after some research moved my 2 goldfish to a much larger tank. Now there appears to be a whitish sore on the fishes side and his swimming is not exactly right. Any ideas?
Not sure if you cycled the tank before upgrading – not doing that can cause further stress.
So my fish has like a bump that has a hole inside it does not bother it what is it
Could be a tumor…
A couple days ago I noticed a small bump on the edge of my fish’s tail. It is still there and I’m starting to get a little worried. It’s white and I’m confident it’s not ich. It’s slightly bigger and I wondered if anyone could help me figure out what it is and how to cure it.
White is a sign of an immune response to irritation, not always ich.
My goldfish is barely moving the last few days and on his side his gills are still opening but slowly his eyes are bulging..we have another goldfish and he seems fine?? Help
It sounds sadly like it is time to euthanize. 🙁
Me and my sister have a goldfish each. My Goldfish has an odd brown spot on its head, dead in the centre. My goldfish (named Jam) is in the same tank as my sisters fish.
The tank is a bit dirty as I am busy with school and am sometimes unable to cater to it. It seems like a white layer of skin is over the top of the spot too. I am not sure what to do and I want my fish to live, he is important to me to an extent that I am unsure people will understand.
Please answer ASAP, I will keep searching online for anything.
Thanks.
A dirty tank is definitely not a safe environment for your fish.
I have a fish that is has a swollen belly and underside….
Eating normally
Is there a way I can help it
please take a look here
https://youtu.be/4yi7zzeSgR4
That looks like either egg impaction or a severe abdominal infection. The fish needs to be put down 🙁
My gold fish seems to have a smooth white bump on it’s body… it seems to be growing from under it’s scales, I am nervous.
That sounds like the start of a tumor.
My goldfish has a patch of brownish black stuff on top of his lip… It’s been there FOREVER and some recently started growing on one of his fins… Please help me I’m scared it will pass on to my other goldfish in the same tank… At first it was white and later turned brownish black like it is now. Please help this happened with my last goldfish and he died 1 week later…
Sounds like color change, or ammonia burns.
My goldfish has pop eye. … but other than that not only it’s belly but entire body appears fat than before… its colour has become more bright than before but is active and eats food also… any help please…
That sounds like an internal bacterial infection.
one of my fish has recentky been at the bottom of the tank barely moving for about a week but today he has been really bad flopping and staying on his side have taken him out the tank and put in a bowl of water ..he got a bit better in there aka not flopping as much and was swimming a few cm at a time ….he does get like this at times but never been this bad ….what could be wrong as the other fish that is in there she fine …they both are comet fish she is a lot bigger then him and always has been
The fish may be experiencing some kind of irritation.
I have a goldfish, I though it had ich but it was fluffy spots instead of hard looking and it peeled off like he was shedding his mucus. We bought ich guard and we’ve been putting it in every 48 hours. Today I checked and his entire tail was gone except two lines on the top and bottom. I’m afraid it reached his actual body, but we rubbed it off with our fingers. He’s had the ‘ich’ for about a week and a half. We got all of it off, or all the stuff that was hanging off, we changed the water and took out the filter part of the filter but kept the filter running. After putting ich guard in the water the first time we got it he was up and his appetite was back, before he was hiding under his beta buddy moss and looking dead, very little gill movement at all. He is still a strong swimmer, even without a tail. He has no friends with him, and the net is his net now. I plan to check every day and see if his tail is growing or the white mucus junk comes back. All pet stores are closed and I hope to go tomorrow and pick up mess for him. Any tips to help for now?
That sounds like a fin rot or fungus more than ich to me.
My teacher’s fish is lying on its side, and isn’t moving. It’s still breathing, but barely it’s kind of gasping for breath. There isn’t any sign of paracites, the tails and mouth are normal, all the other fish are fine. And she changed the tank water. She added salt. Is there anything else we can do? We haven’t tried the peas, will green beans work?
You can feed green beans without the shells, if they are steamed first.
One of my two fish just died recently. Is there any way to be sure that the other one will live?
Yes, read The Truth About Goldfish 🙂
So I recently took a couple of fish off a friend of mine. She had purchased them along with a larger tank, but they would eat smaller fish.
so ive got them in a holding tank, about 10 galleons. ill be picking up a 35 gallon this friday
.
problem is, the fish i have is about 7-8 inches. ive noticed a soft looking white fuzz spot on the fishes nose? as well as what looks like a small scab on the tail. He is a bulging eye goldfish, he had slightly clouded eyes when i had gotten him. the prior owner clearly had not taken proper care of the tank.
I try and do a partial water change every 1-2 days to keep things clean as I can for him.
He does hang out near the top of the tank quite a bit, but i turn the light off and that stops, so I assume hes just hungry. Got any ideas?
The cloudiness should clear up if you take good care of him.
I have two goldfish but one has become very lethargic over the past week or so. He sits at the bottom of the tank most of the time and just floats about.
I came home today and his fin had been sucked into the filter, no idea how long he’d been there! Obviously got him out and his fin seems ok. Done a large water change and cleaned the plants and filter etc (in tank water) any ideas what’s wrong with him? Is he just stressed?
The current could be too strong for him.
i have a pet goldfish and he has begun to grow some brown stuff on his forehead and lips. any help?
It could be color change, or burns.
if it is burns could it be because of the water?
Yes definitely.
i have replaced his water and he is acting better and the brown spot on his head is healing. he is doing great now thanks!
I have 6 goldfish. One of them has a top fin that is turning white. Its ny biggest fish. It is behaving normally, and there are no signs of any sicknesses.
Also, he is acting like he wants a friend, even though there is so many fish in the tank… please help…..
He is probably just excited to see you 🙂
Hello my 6 yr old fish has suffered some amonia burning and has been ok for the last few days w constant water change and product to help the water settle though he has now developed a sore which is inflamed where there was a patch of black on his side and the scales are sticking out a bit as the lump pushes can from with in the body . I want to treat him w human anti biotic anmoxocillian can I do this without harming the fish ? Thanks
No do not use that. It is not fish safe and will cause more harm than good.
Hello I have a fancy goldfish in a 5 gallon tank of unheated fresh water. he has small white fluffy spots on the tips of his tail. Some with short white stings (around 1/4 inch) coming from them. I have been reading your posts. I think it may be fungus. Will it help to add salt to the tank? I have never had salt with this fish.
Thank you
I wouldn’t salt in a 5 gallon as the water volume isn’t sufficient enough to be stable. A bigger tank is the starting point. 🙂
My fish has a bump on the side of her body, and its not hanging by a thread is there anything i can do besides going to a surgeon?
We do outline a tumor treatment plan in our book.
My fish’s fins seem to show some disentagration and the fins and body have developed some black areas in the orange and have since died. Does anyone know what this might be ?
That sounds like burning from high ammonia.
I have a rather large goldfish in a tank outside alongside a carp. The goldfish seems to have a wart or worm protruding from its head (very certain it’s a wart or growth) and it tail is bent to it’s left though still has some mobility. Sorry for being so vague but I really just want to help the little guy but don’t know how.
If it is a wart that could be a tumor. A bent tail could be scoliosis.
Hi,
My goldfish started to quickly develop little bumps on the upper side of his body and texture on his forehead. The skin on the bumps is normal. His eyes have been a little swollen too. Today, i saw bubbles in his poop. I’m thinking it might be the gas bubble disease but it doesn’t look like any of the pictures i see online. I was told at the fish place that it’s tumours but i highly doubt it… Thank you for your help.
Bubbles in the poop means the fish is sucking air. You likely have a bacterial infection going on.
i had my fantail goldfish suck air he got swim blatter and u can treat it with frozen peas (only fantails get this)
Our goldfish of 2 years just had his tankmate die of old age, he now only sits in the corner, won’t eat food and is starting to show signs of fin rot. We already got him a new friend, what else can we do or what else might be wrong with him?
It could be because of the same reason the first died, and is now affecting the other.
I have a young goldfish that had developed several small circular lumps under its scales mostly on its head and front of its body. Today, one of the larger ones has opened and is presenting itself as a white mass. Would these be tumors, are they contagious and what can I do to treat this?
Thank you!
That does sound like tumors or a fungal infection.
I have a question more than a comment I am wondering how to treat my fish seems to be having trouble staying upright keeps turning over found him laying in the bottom of the tank early in the morning in a corner upside down seems to swim around and want to eat but can’t stay upright what do I do
I would recommend that you definitely check out the emergency care plan in our book.
Hi
My oranda goldfish has a tiny orange lump which has formed just next to its top fin on his back. It’s small but noticeable
It’s definitely just orange and about the size of half a pea.
Any idea what it could be?
That is probably a tumor. They are often found in that location.
I need some help.
My bubble eyed goldfish for a few weeks now has seemed to loss through interest in swimming around.
It looks like it is hard for him to swim around and move. Sometimes it looks like he trys to and then just slowly drifts back to the bottom. He barley moves even when it’s feeding time too.
He used to be the liveliest swimmer in the tank. And I had just lost one of the three goldfish in the tank a few weeks ago, and right before that happened, this fish started not swimming around also. I desperately need help!!!
How long has the tank been set up? It could be related to overcrowding or an uncycled filter.
What is the “kindest”. Form of euthanasia
Freezing is said to be the least painful.
My goldfish seems really ill I don’t know what it is I need help fish are cared for really well feed the veggies etc check ammonia levels etc and we treat them regularly but she has what I can describe as a swollen bum and we thought maybe ready to lay eggs? But nope as the day has gone on she has got so much worse to the point it’s very swollen and white string is also coming out! And this is not poop she had one this morning and it was strangly abnormal in size (huge)! But the string is what I could describe as looking like a build up of worms (although not worms!) please help I don’t know what to do she is with others
The string is a cast, not worms. No worries about that. Swelling points to bacterial infection.
My Orandas loose their ability to keep an even bounce and the fantails become shredded. They do still come to the surface to eat. Eventually they die.
I have 2 fantail and onr black telescope .one of them keeps like staring in the corner and the other one keeps hiding underneath one of the log decerations.
What’s wrong with them? 🙁
It sounds like they don’t feel well. I’d test the water.
I have 3 goldfish and all them have big bellies but no spiked scales. Today I went to go see them and all of them seem to have tiny red spots on the top on the first row of scales. I’m not sure if they were there before but I am 95% sure they weren’t. One of them was also sprinting across the 45″ aquarium. I don’t know what’s wrong with my fish and done so much research on what to do, I can’t find any thing. We also got them about a week ago. Plz help!
It could be just the lateral line, but if it looks like blood than that is a sign of a problem. Chances are the tank is not cycled.
What about the big bellies?
That could be caused by overfeeding.
How do I treat to big bellies? Oh, and what is goldfish poop supposed to look like?
Less feeding, and poop is usually the color of their food.
My new fish we got about a week or two ago first had a long string like thing come from the bottom of it then it came off now it has this large whit bubble like thing forming under its mouth and the fins on its tails are starting to fall and get stringy i have no clue what is going on please help.
I meant White*
If the fish and tank are new, you could be dealing with new tank syndrome.
Ok the white thing came off and the back fin came completely off but it can still get around we don’t know what to do.
It may be time to euthanize…
My four small (inch to two inch) goldfish are in a 60 gallon tank and I left for four days for my Mom’s funeral, when I came back three have small white on the front side of the upper fin on their back – the tinyest one a black moor has it on the two dots on the tip of his tail…doesn’t look like ick could be fungus or pox how do you tell which is which? Or do you think it is something else?
I did remove one red cap with bladder issue that is better and one fantail that keeps wedging between rocks and has scraped side so it is still in “sick tank” with antibiotics (but is happy, swimming, and eating).
Please advise – Thank you – JWE
Sorry for the loss of your mom 🙁
It could be a sign of irritation. Did you test the water?
My goldfish has grown a yellow patch of skin right under its fin? Any explaination or recommendations?
It could be a tumor.
My Goodrich is growing bumps from the inside of its body and idk what it could be or how to treat it any help.
Possibly a tumor; see the tumor section to check.
I need help.In my two inch common goldfish’s tank I found two worms. I think they might be tapeworms ( they kind of look like the rice looking ones my dog had). I found three. I have had my fish for over a year now. Even though it is a common, it has never opened it’s fins completely. Can you tell me if i’m really dealing with tapeworms and what to do to deal with the problem. The worm is small and white with (what I can tell) black ends.
Planarian worms are likely what you are seeing, but they are small.
HOW TO CHANGE A COLOUR FOR A GOLD FISH
HI
i HAVE AN OUTSIDE POND ABOUT 2500 LITRES. I have recently emptied and resurfaced the pond with fish friendly paint and sealer.and some ph leveleer that the fish shop sold me.. i put the fish in the resurfaced pond and the plants as these were all in other ponds . while the resurfacing was done…the fish seemed to just sit at the bottom of the pond.three died by the morning. so after a couple of weeks they werent eating so i checked them the appeared to have blood under scales on their bellys. so i took them out of the pond and put them in the other pond..i have empty the resurfaced pond. Now i have one fish dead and no tail. one fish is swimming upside down.. i have put the remaing 12 fish in a 30 litre bucket with a air stone and added tonic salt 3 heaped tablespoons.. they appear to be a little more active… i have another tank of which i have a filter and salt in . shall i move them into this. i have been adding a cup of the new tank water to the bucket for about 2 hours now… also when empting the resurfaced pond the grasses and water lilles has a strong stink smell (wondering if they were sitting to long in the resting pond waiting for the resurfacing).. i have had the pond for 12 years and never had a problem untill now…. the closest pet shop is an 2 hour drive there and back.. do i treat them with melafix bacterial treatment … HELP..
It sounds like something went wrong with the sealing process. Do not use medications, you will not be able to put them into the pond until the issue is addressed.
Hi Pure Goldfish!
Ive been having some problems lately with my 3 fish, i have two orandas and a baby ranchu, So today when i changed the water i think i might have poured water with the wrong temperature in the tank, because when one of my orandas swam towards the stream, of the siphon it came back with dropsy and under one of his scales i could see something white sticking out (i thought it was a anchorworm at first glance but it isnt anything string its more thick like cotton maybe?) , it was also red around it. I then called someone at a large aquarist shop for advise and they told me to put some salt in the water so i did and the scales have been progressively better and not as pine cone ish anymore. Just now i realised that my baby ranchu is bottom sitting and that a patch of his scales loock red around them, they kinda look irritated. I really dont know what to do and i live in a small town here in sweden so its not like i have an expert next door haha.
Temperature wouldn’t cause that, as much as perhaps the wrong tank size or wrong tank maintenance system.
Hi, my goldfish has a clear bubble on the side of his tail fin with something green in it. I’ve searched up and down and cannot seem to find what it possibly could be. I could use some help! Thanks!
It may be a gas bubble.
Hello, please help!
My goldfish has had constant white discharge from one of his nostrils. When it dislodges, more comes out. What could this be?? I didn’t feel it fit anything from the list except maybe fungal. But it is a cotton like white substance from his nostril. I have had him for a few months and nothing has changed in his tank care. He has had a recent loss of appetite.
It could be excess mucus production in response to stress.
Hey there, your site is Very informative and I like all the illustrations. I wish I could attach a pic of my problem. I have a 35gal tank with 3 mature fantail goldfish (3+ yrs) and a new (4 days) freshwater crab. I can’t find the crab and suspect he got eaten…but while looking for him, I noticed one of my goldfish has NO GILL!
It looks like his gill just rotted away or something. There is a red slash that looks like someone cut a slice out of him where his gill covering used to be. His other gill looks fine, and he is eating okay and moving like normal…just looks like his gill fell off! It’s not super noticeable…he looks just kinda…off…until you see it.
Do you know what this is and how I can help my poor fish?!
Thanks!!
It could have been from injury, the gill could have gotten torn off. Nothing you can do to fix it.
Hi I have a gold fish its about 5 years old it is in a 66 litre tank it eats normal looks good only for one thing it has developed a large lump on its side it is pinkish in colour any idea what it could be
Tumor?
Hello my goldfish has a big knot or lump on its head I don’t know what this is but my fish has recently stopped moving a little. Pls tell me what this is I want to help it
It could be a tumor.
I have 1 large gold fish about 4 inches long in a 30 gallon tank.I bring him in from our pond every winter.I took in a friends little fan tail goldfish her son didn’t want.This little one attached the big one till his scales are damaged.I removed him that evening.Now the little one has white spots on his face and my big one looks terrible.The little one is now in another tank.
how do you snip off a goldfish tumor? my goldfish Happy has one hanging by the thread.
Small medical scissors.
My goldfish has got fin rot disease and also Pop eye with the addition of its belly which has increase in size,his fin has stop rotting but the eyes are popping out more everyday,the upper side of the fin has completely rot and the little left has become white like Cotton wool disease,I think its too late for saving it but have you some little tips to prevent the other goldfish to be sick?
What is the kindest way to euthanise my beautiful Blackmoor? He has lost all his colour within about 6-7 hours and is on his side or head down since I put
him bac in a clean tank after a 2/3 water change. I took him out of the tank whilst I did it but kept him in a 5 litre tank with some of the old water. The Ph and
Ammonia levels are both just right. I put him into a smaller tank with the aerator going and HAV added some
Salt
To the water as well. It’s almost like the new water was too clean! I don’t want him to suffer but if u can offer anything else it would be so appreciated. His scales are not
Pine coning but he is breathing quite rapidly. Thnks
Freezing is said to be the most humane way. :/
Hi, I have a problem. I have two goldfish and have had them for a while, I changed the water of their tank last week the same way I normally do and since then one of my fish has been growing a bump on his head and a light brown film on his gills, I have separated him from the rest and the others are doing just fine. What might he have and how might I be able to help him?
I have a white fancytail lately it was being quietly and it was swiming in his sideway what happen and it look like his scale is losing
Check ammonia.
My goldfish is a 1 1/2 year old comet. She has red blotches around her eyes, a couple on her body. One spot has pitted and she lost a scale from there. I’m treating her with Kanaplex. The red blotches seem to be getting lighter . She is eating and gaining weight. Don’t know what to make of this. Should I continue to treat her with the Kanaplex.
Thanks
My gold fish has a bunch of red spots all over its body with red streaks on the fins and the other 2 smaller ones and starting to get red streaks on there fins. I noticed this once I got two new plecos to their tank. They have been sluggish and lost their appatite. Any treatments I can do to help rhem? I have changed the water in the tank to try to help it.
Hello there, recently my common gold fish developed a fairly long white growth on his underside, it didn’t look like a worm (I checked against pictures) but more like a tiny bunch of white grapes. I think he managed to scratch it off, but there is still a small bit left and it has left a small red mark. Any idea what this could be? Thanks
Could be the beginning of ulceration after irritation.
I have goldfishes and on some there are orange coloured dpot on there body why they are so please if any danger then tell me the treatment also?
I have a fish that has a lump on its tail it is a clear lump and it has had one before, it popped when we took it out to clean its tank but it came back do you know what it is??
Hi Pure Goldfish,
I have a goldfish which like to stay motionless at the bottom of the tank. It will stay in rest mode the whole day until feeding time when it will start to become active again. As it stayed too long at the bottom, a small patch on its belly had became a bit reddish like some sort of a sore. It does not have clamped fins and it is eating fine. Is there anything wrong or it was just a lazy goldfish by nature? thks
That does not sound right to me.
Hi Pure Goldfish,
I have some goldfish with 3 koi’s last night 2 of the koi’s had cloudy eye and then when I woke up some of the goldfish had cloudy eye and most of them were laying on the bottom so then I added required amount of aquarium salt for my 20 gallon. What should I do???
My black Moore has fin rot and lumps on top of his gill what should I do
Comet goldfish ive owned for 10 yrs,, these past 3 years ive been trying differnt ways to get rid of its tumor it has slowly developed..I would notice the tumor sword of start going away so i would stick with that treatment but it would just grow again to its regular size ..if anyone has had this problem or anything similar or have info ide appreciate it. Thanks
If i have a black goldshish and all of its skin is peeling off and its barely moving is that the itch?
Doesn’t sound like it.
Hi Pure Goldfish,
my fish has a strange bulge that just appeared over one eye. It has also been floating upside down for a little while, but continues to eat. I have tried feeding it peas, but it had no effect. It is in a tank with another fish that is fine. I have had both for around 8 years. What would you recommend?
Thank you

My Goldfish has an open wound and i currently have it in a quarantine tank treated with melafix and aquarium salt. Do i need to add a heater as well?

Hi
I have two goldfish as pets they are both fantails and are the same size.
But one of them is constantly being nasty too the other nudging into it even pulling at its tail. But recently I noticed part of my fishes Gill is missing. Could the other goldfish have caused this?
If not could anyone tell me what could cause this to happen plse as I wouldn’t like too think this fish ? is in any pain or discomfort.
Any advice appreciated 🙂
Thanks
Julie
I don’t think so, but it will cause stress.
My fish’s tail is in strands at the tips and there’s white at the bottom of his gill area. There are other fish in there with him and I don’t know what to do. His tail keeps on getting sucked into the fertilizer and I’m really worried. Help!
Sounds like an advanced bacterial infection, separate him right away.
I do not know what is wrong with my fish. His fin on the top of his back suddenly got red spots on the fin. He is moving kina like a snake. Can you please tell me ASAP what is wrong with my fish.
He is eating and when I look at the Finn when I turned the light on the tank on the fin has small white little bumps. PLEASE HELP
I have one bottom feeder and four gold fish. I recently found my gold fish has chunks of what seems to be skin n scales missing all over the body including the edges of its tail I was wondering if the bottom feeder or if possible one of the other gold fish could of done this?
mine has missing scales also the bottom feeder is harmless and the fish do not harm other fish because they arent carnivores its most likely your fish is missing scales because hes growing
my fish has white spots where scales are suppose to be hes not eating and almost always rubbing its mouth against the sides of our tank! i change my filters regularly sh whats the problem??
My fish has a bump on its side but its chasing the other fish like he wants revenge, what should I do?
THANK YOU SO MUCH!!! I have been treating one of my goldfish using Ich treatment but the pictures you show have educated me to the fact that my fish has tumors. None of my other pond fish have this so I figure all I can do is keep “Bumpy” isolated in the aquarium. It still eats well and is active.
Happy to hear it helped, Virginia!
“You can treat Trichondia with a high concentration of salt, anywhere from 0.3% (which is 3 teaspoons per 10 gallons) to 0.9% (3 tablespoons per gallon).”
If a tablespoon (15ml) is bigger 3 times than a teaspoon (5ml) it must be an error for the number of gallons: they have to be the same one or 10 gallons for both, as 1 tablespoon is 3 teaspoons, so if 3 tsp is 0.3% then 3x3tsp is 3×0.3%=0.9% for the same amount of water.
Please correct the text as if is too diluted (10 gal) is inefficient or if is too concentrate (1 gal) it will kill the fish.
Thanks for pointing that out; will fix 🙂
We have a bubble eye two years old who has become very lethargic – resting at the bottom of the tank for long periods – it has small dark greenish grey scale size patches more towards his tail and a couple of red spots on one side also scale size.
Did you test the water?
We took a sample to aquarium – it was 16 degrees , turns out we had two shells in tank that were affecting temp , hardness etc – we were given a dark green fungus cure and told to swab the fish , rinse and return 3 times in three days, after swabbing large red patches has appears and he is floating on one side on bottom of tank (drawn by filter) and bent to his left – slight movement of fins and gills working –
Got small to large red (same color as fish)and round growths on body and head over 3 years.
I have two Coral goldfishes. There’s a 5 cm and a 3 cm one. Both the fishes have a bump on top of their fin (it doesn’t have any color, it’s just their skin, but with a bump), have specks of white dots (like how you described ich)on their fins & body, and a reddish orange color on their face. Aside from that, the 5 cm one has red specks on her head and near tail part. She also has a clamped fin on her left side. The 3 cm one has greyish-greenish-black spots on the bottom and has a white worm coming from in between her tail fin and fin. It also has a black line on one of her fins. I don’t know how to treat these diseases/disease. I’m not sure what the disease is after adding all of this up. Their behavior has changed, they rub on each other, or just have light touches and bump into each other all the time. They are not that active, only when food is given, they jump around inside the water a bit. After that, they’re back to a dull mood. Please help!!
My goldfish has been lying on its side on the bottom of the tank for a while, but did get up and swim around ok for food, then returned to the bottom. I moved it to a “hospital” tank on its own with a treatment for swim bladder problem bought from a pet shop. It seemed to make things worse! the fish looked as though it was dead, and completely turned over upside down. It is still breathing, but totally upside down and doesn’t seem to want to move around at all. I don’t want to repeat the swim bladder treatment as it seemed to make it so much worse, is there any other treatment I can use that is more “friendly”??
My fish done same thing I took him out and put in another tank I would bring h up yo get air several times I would put him on hos belly against air filyer now hr navl in his tegalar tank doing fine
I had itch in my tank all fish have died I emptied the tank n cleaned it n filters then I filled Filled it added vinegar n run tank for a week now I have emptied cleaned filters with boiling water what do I do now
Cycle the tank before getting more fish.
Hi my goldfish isn’t active anymore isn’t eating anyways to the bottom of tank also has 2 black marks on fins doesn’t seen to be breathing quite well
Ammonia?
Could be fish lice. One of my fish has them and I’ve performed surgery twice now. They are hard and crunchy and don’t come off easily, like taking a tick out of us. Put fish lice medication in tank too. Clean the tank a lot., more than usual.
.
I have one gold fish in a 40 gallon tank. He has a transparent “bubble looking” growth on his rear fin. I have been researching possibilities of what it could be to try and treat but keep on hitting a deadends. He swims around just fine and has a normal appetite. It doesn’t appear to be bothering him at all. I can tell it’s growing as it’s gotten larger. Any ideas?
It might be supersaturated gas related. Take the aerator off your sink for starters, if you have one.
This also sounds like fish lice.After a lot of reading, I found out that the only parasites that are big enough to see are anchor worms and fish lice. Sounds like fish lice and you have to take them out with tweezers, which is hard because they really clamp down and are crunchy crustaceans. Then I dab mercurichrome afterwards. I put a heater on 75 degrees (they are goldfish and I normally don’t heat the water).Put 4 Tbl. aquar. salt for 20 gal tank. in water. Put fish lice treatment in water.(supposed to take care of eggs). Clean the tank a lot.
One of my goldfish has what it looks like a red pimple on his side. It’s very small. It only appeared a couple of days ago. He is swimming and eating normally. Any ideas of what it might be and how to treat it?
It sounds like the beginning of an ulcer to me.
I think it is a tumor.
Hi. Good day. I’m really worried about my gold fish. He has something in his head something like fungus. At first it is just small then I transfered him into another tank to cure him with methyline blue, but then I noticed that it was getting bigger and bigger and I think that there’s a vein on his head connected to it .maybe it’s a tumor.. kindly tell me what to do. thanks. and by the way I sent you message on facebook.
So my daughter recently won a goldfish from a carnival and has had it for nearly a week. It seems healthy, swimming around his tank and eating all of his food, though hiding if you get to close. She has been working extra to keep him alive and has been pestering me for things to get for him. Today though, as she was cleaning out his tank, she noticed some sort of blackish-brownish thing on his side. Is this an infection or disease or just part of his scales? He is a common goldfish is that helps. And if it is bad for him, what is it and what do I do?
Black is usually from ammonia poisoning, it is healing after the burn.
Hi. We had two shubukins. One died last month. Not sure why but did look slightly slimey on body. Now remain fish has three white spots on edge of tail. Is eating and active. Have cleaned tank. I felt it coulld be two or three of the above. Any pointers? TIA
It could be ich, but give it some time to see for sure.
Hello there! I won 7 (yes seven) common goldfish at a carnival recently. A couple of them have developed cauliflower looking lumps on their heads. I thought it may be Ich, but I wasn’t sure. Also, some of them have developed a rusty looking brown substance(?) on the edge of their tails and dorsal fins. I’m not sure what this is, either. Can you help me?
The cauliflower lumps definitely sound like tumors or virus. The rusty substance, is it dark like ammonia burns?
Had my goldfish for a few years now but noticed that it has swollen on both sides what can this be the other fish in tank is fine
It could be a number of things, from eggs to infection. You may want to test the water.
My small fancy is now producing long, dark/greeny black looking poop. The poo is about an inch and half long and trailing behind him. What can I do to help him? We have just cleaned the tank completely. Any suggestions?
No worries, it’s from what he’s eating. That’s actually a healthy stool.
Hello my gold fish have blood on fins and he’s hau too help him plays Hello my and his laying on botom not moving it’s really sciers my wath I need to do
I would recommend testing for nitrites.
My fantail is 3 years old and always been healthy but have noticed a large flat but raised lump on his side that looks slightly bloody colour not sure what it is?
That could be the beginning of an ulcer or tumor, but if it is raised that points more to a tumor.
A couple months ago, I bought some goldfish to stock my backyard pond. One of the fish I purchased isolates itself, stays near the surface of the pond, and eats little. It can move quickly and move about but does not seem too ambitious. It has a small white spot above where its brain may be. It is not raised or granular, but smooth. The fish always seems to be looking as if it wants to climb onto the land. Any ideas as to what is going on with this fish? It is only about 4 inches long.
If it is an oranda, it may have wen growth where the white spot is. Or it could be the start of an ich outbreak.
I have a four year gold fish six months ago we noticed a small bump tumor looking thing on the top of his head now it’s just huge about half the nice of his head hanging it started off a white color now it’s still white but kinda bloody looking it still swims normally and eats normally we used to love to just watch him swim but now it just grosses us out I have always change his water about every 3 weeks now just when the water starts not to look clear I change cause the growth is bothersome…just wondering what this might be or what maybe we could do?
It sounds like a tumor. More frequent water changes may stop the progress.
we have a big goldfish who lives with our five other fish. we noticed that lately he suddenly has a bright red blood lump on his side. we looked on here and think it is an ulcer. unfortunately, the only thing we can do is change the water because we have other fish we cant add salt to it, and scrubbing the fish could kill him. he continues to swim sideways, and even though he does eat, he stays at the surface level with his blood clot ulcer sitting out of the water. he spends almost all of his time up there, and sometimes we find him lying so still we think he is dead, but then swims off. can you give us an estimate on how long you think he may have? we have had him for maybe a year and a half, maybe longer. we want to try and save him, so can you help us please?
On no 🙁 Have you tried testing the water?
my shubukin has become lethargic + stays at bottom of tank have moved him to separate bowl ,no visual signs of decease showing what should I do ?
Has he been living in a bowl? If so he could be suffering from ammonia poisoning.
We tried that…..its fine. but suddenly the giant red lump which we thought was the ulcer, has disappeared, but there are still three small red blood streaks on him. now upon further observance, the previous area with the ulcer has turned white, and he is missing scales! the area he is missing has turned white. he doesn’t like the move much but continues to eat and breathe, along with sticking his side up in the surface air. we turned him over, and saw that also missing scales on his other side! What can we do now? ??
Definitely do a water change, but did you test for ammonia specifically?
also our black fish seems to be nibbling at his side. can’t tell if that is irritating him or helping ??
That’s definitely bad 🙁 Take out the bully right away.
I have a year old goldfish that has developed a bend in the body. He is shaped almost like the letter z. Another one of my fish has done the same thing. Has anyone any idea what is causing this. They both seem to be eating OK.
Check for electrical current leaching from the heater or underwater pump.
I have had a terrible run with my tank. I got a 10 yr old suckerfish, added a pearlscale about 3 weeks ago from another tank, and then added a Ranchu 4 days later from the same tank as the pearlscale. The Ranchu died for no apparent reason, water test was all good, except pH 7.8, so got pH down to 7.4, added a new Ranchu from pet shop. The next day pearlscale showed white spots all overits fins & head- treated for whitespot as per advice from aquarium, she dies 2 days later, so did a 30% water change to dilute chemicals out, then the new fish developed white spot, so retreated with white spot chemical. the next day, I found the 10 yr old suckerfish dead at bottom of tank, the ranchu’s white spots have gone, but it now has bright red blotches under it’s skin on both sides, and around one eye, like a haemorrhage, it looks lethargic. Can’t find any pics on google to explain what it is. The pet shop didn’t know either- I’ve added melafix tonight. The tank has a filter and air pump. Does anyone know what the red blotches may be? Also, it looks like some of the slime coat is hanging off the fish tail. The only other thing I have done is add a new drift wood with plant about 3 weeks ago. Thanks in advance for any answers.
Some of this can probably be attributed to the stressed condition from the fish at the pet store to begin with, not necessarily all your fault. Red blotches can be from parasites or high nitrites.
i have a dirt bottom pond for my goldfish, they are active and growing nicely. i’ve noticed that some of my fish which were completely gold have started developing black fins. Is this something to be concerned about or is it part of their development?
This site is informative and interesting. I will use it to help me solve problems with my fish.
I would test ammonia, as sometimes blackening can be caused by high ammonia levels. Glad you liked the site 🙂
I have goldfish in an outside pond, today when I was feeding them, I noticed one has several small smooth pea-like lumps on its side. Can you tell me what it is, and if its treatable, thanks.
What color are the lumps?
They were the same colour as the fish, but now some are no longer smooth and are starting to look a little whitish.
My largest goldfish has a white bump on his side (looks like a big whitehead).
He doesn’t act sick at all….but it seems to be getting bigger. It looks like it would pop if it was squeezed. Any ideas as to what that is or what to do? I have 11 goldfish in a 220 gallon sugar kettle outdoors.
Thanks in advance.
Is it raised or fuzzy?
I got a goldfish my mum told me that fin didn’t look so good I tried everything but sadly he passed away ?????
I\’m so sad that fun died in only 11 please tell me was there a way to save him
Did you test the water?
No I didn’t have a water testing kit fin’s death still haunts me today
:'(
Aww sorry to hear that 🙁
My large outdoor pond has only goldfish. I took a really big one out today because he was upside down and almost as fat as he is long! I think it may be dropsy. I put him in a big bucket with air and some antibiotic powder but I read on your site there is no hope?? My biggest worry now is if ALL the fish can get it?? Also, a lot of frogs keep laying eggs in there and it always seems like when the fish eat too many frog eggs they die. Is that true? Can that cause dropsy?? I’m very worried the whole pond could be infected now…
Are the scales prickled? Dropsy shouldn’t be caused by frog eggs.
We have 2 white goldfish in an outside pond, one has a big lump on his left side. They only eat pond weed because for the first few years we didn’t know they were there! Last summer one developed the lump approx 2cm but otherwise they both seem fine. Is there something I can do to help him/her? It doesn’t seem to be getting any worse.
Tumor maybe? Good water quality can help stop the progress.
I need help, I just got a couple goldfish the other day, they all looked pretty good, no symptoms from the list, it one of my fish (note he is the biggest one of the comet goldfish) has a huge blister like bump on how head, it’s translucent kind of clear. He he was the same size as the rest of them when I bought them but he has gotten much larger than the rest of them. I don’t know what is wrong with him, he doesn’t seem to be acting weird besides he is swimming really fast and eats a lot more than the others. Any help would be great.
Could it be a tumor? It may be gas bubble disease from supersaturated air.
Honestly most informative article I’ve read on fish..anytime white spots are mentioned everybody says it’s Ich..Ich..Ich..well thanks to this article I finally found out what the whitish crusty things are on my fantail goldfish tailfins..not Ich..thanks!!!
Haha great to hear, Maxi Maxi!
so my goldfish has 2 little bumps 1 on each side that looks like its either coming up from under the scale or the scale itself is the bump. i have been watching it for a few days and it doesn’t seem to be getting bigger but i’m a bit worried about her
Try to keep the water clean, it might be a tumor.
