Ich! 5 Steps to Treating Goldfish White Spot Disease

How to Rid Your Tank of Goldfish Ich (White Spot Disease) in 5 Simple Steps

What is Ich?

Ich!  It sounds like what it is… a tiny little parasite that gradually covers the body and fins of your precious goldfish until they look like they’ve just come out of a snow-globe.  Ich, short for Ichthyophythirius Multifilis, is common in aquariums that contain recently purchased goldfish.  Does your goldfish have ich? Common symptoms include:

  • Flashing (scratching and rubbing on objects in the tank)
  • Clamped fins
  • Lethargy
  • … And white spots

Sometimes goldfish ich can cause difficulty breathing and red skin, but this is less common.  Once you’ve seen ich, there’s no mistaking it.  The manifestation of white spot disease is far different from the breeding stars that appear on the gill covers and pectoral fin rays of male goldfish during the warm months of the year.  Ich will affix itself to any part of the goldfish’s body, save the eyes, and continues to multiply with time.

If left untreated, the goldfish can die.  This is because this creepy creature does considerable damage to the gill tissues of the fish, suffocating them through lack of oxygen. So what can you do to help your fish?  Understanding the life cycle of this pesky protozoan is the key to eradicating it from your aquarium.

In a nutshell, ich is one of the most common parasites of domestic fish.  But the tiny white spots which can appear fuzzy up close are actually not the ich parasites – they are the goldfish’s immune reaction to the parasite underneath its skin.  You may not always see the visible white spots when your goldfish has white spot disease.  Depending on the conditions in the tank, this disease may only be detected with a microscope.  If your fish flashes, clamps its fins and acts lethargic, it may host a vast number of ich organisms though it shows no speckles.

Goldfish do not always come down with ich.  The goldfish may be able to fight off the illness on its own before any white spots ever appear.

The Life Cycle of Ich

Ich enters the goldfish tank through the water.  (Let me say one thing about this: when you buy a new goldfish, please do not dump ANY of the pet store water into your tank EVER.  You do not know what invisible pathogens it may contain.)  At this stage, the creature is “free-swimming” like a goldfish fry, and seeks to latch onto a host.  When it finds one, it buries itself underneath the skin (yuck) where it grows and grows until it the skin bursts, releasing a packet that falls to the bottom of the tank.  From there, it continues to grow until it bursts open to release thousands of more free-swimmers that begin searching for a new host immediately.  The process continues until the tank is completely infested.

Treating Goldfish Ich

Controlling the temperature of the tank can help you clear up ich much faster.  While it is lodged in the skin of the goldfish, the protozoan cannot be touched by any cure and can remain there for over a week in low temperatures.

Because the pathogen can only be killed during the “free-swimming” stage, raising the temperature of the tank speeds up the life cycle of ich and allows you to kill the parasite while it is vulnerable.  Then you can destroy it with the treatment.

At Pure Goldfish, we prefer to go the natural way when it comes to goldfish treatment.  Store-bought medications are not only pricey, but they are very dangerous to the stability of the tank because they destroy the beneficial bacteria needed to ensure stable water parameters and stress the fish themselves. Recent evidence shows that strains of “Super Ich” are showing up – resistant to the traditional methods of salt and heat.

Why pay for something that could potentially destroy your goldfish community when you already have what you need in the kitchen cupboard?  Non-iodized sea salt (which cannot have any anti-caking agents) is by far the most effective and safe treatment for your goldfish tank. You can get aquarium salt here.

Follow these five steps to cure your goldfish from ich:

  1. Gradually raise the temperature to around 80 degrees Fahrenheit. Ensure plenty of aeration as warmer water contains less oxygen. The higher temperatures speed up the life cycle of ich, helping you get rid of it faster.
  2. Remove all live plants from the aquarium, if there are any.  Salt will damage or kill them.  If you have a carbon filter, remove that too. It may be easier to use a 10 gallon hospital tank for a single fish.
  3. Do a 90%  water change to ensure optimal water quality while treating.
  4. Dissolve 1 tsp of non-iodized sea salt (available from most convenience stores) per gallon in a cup full of tank water.  Pour slowly around the tank, and repeat every 12 hours for three days.  This will ensure that a 0.3% solution is maintained.  Between each treatment, perform a 90% water change to remove fallen packets of the ich parasite from the bottom of the tank, replacing the salt you took out into the new water.
  5. In addition to salt, be sure to use Melafix (a natural bacterial infection preventative) during treatment. This is because secondary bacterial infections after ich are common and can be extremely dangerous to an already weakened fish. The ich parasite does considerable damage to the tissues and skin of the fish which are at a high risk of infection.

If you must do a water change at some point of the treatment, be sure to replace the exact amount of salt you take out.

Do not worry if the ich seems to worsen during treatment – this is normal and means that the life cycle of the protozoan is indeed speeding up, as you want it to.  Keep a close eye on the goldfish and test the water frequently to maintain perfect water conditions.

Why Goldfish get Ich and How to Prevent it

Ich is a sort of “red-flag” disease that often tells you something is wrong in the tank, usually a matter of poor water quality.  Toxins that build up in the water from the waste and hormones of the goldfish can damage your goldfish’s health more than you’d think.

It may be a good time to examine your goldfish care-taking habits.  Do you do water changes correctly?  Is your tank size large enough to hold all of the fish you are keeping?  Do you test the water often to keep tabs on most critical parameters?  Are you following a correct feeding regimen?

If you answered no to any of these questions, chances are that environmental conditions are weakening your goldfish’s immune system, making it susceptible to disease. The good news is we have the resource you need to learn how to care for your fish properly:

By putting into practice everything you learn in it, you can help ensure that your goldfish live a happy, healthy life free from ich and other health issues.

Other tips for stopping ich:

  • Do not dump in pet store fish water into your tank along with new goldfish
  • Follow the correct water change and care outline to prevent toxins from accumulating and harming your fish’s immune system
  • Try to choose healthy goldfish from the start to avoid incurring preexisting problems.
  • Quarantine all new fish and only buy from a reputable goldfish seller.

    In regard to the four steps to cure goldfish from ich, are the entire three days of adding saltwater every 12 hours considered a treatment, or is every addition of saltwater a treatment? Also, am I supposed to leave the carbon filter out for the duration of the treatment?

    • Puregoldfish January 31, 2015 at 3:58 am - Reply

      Hi Leslie, thank you for your question =)

      The duration of treatment usually lasts for 7 to 14 days long, which is to say the length of time that the salt remains in the water. I should have made that more clear in the article; thanks for bringing that to my attention. Adding salt to the water in increments is treating the water; but actual treatment lasts over the 3 days. Hope that makes sense 😉

      Regarding the carbon, removing it is only necessary when you are doing some kind of a commercial treatment that the carbon would work against. Salinity is not something that will conflict with the carbon so you can leave it in just fine.

      Wishing you the best in the fight for your fish!

          Great job! I applaud you for taking the time to make sure you do things right the first go around. You may want to keep in mind that ich is sort of a “red flag” to let you know something is off in the tank. It’s important to keep tabs on the water quality and tank stocking at this time to ensure your fish recover quickly.

        Hey, I wasn’t sure how to make my own comment so I’m just going to reply with my question…

        My mom recently filled her fish tank with fish, the tank is 40Gal with 10 double tailed goldfish
        – 4 Black Moor Fish
        – 1 Medium fish about 3 1/2in
        – 3 Small fish about 2 in

        – 1 Multicolored goldfish (black, orange and white)

        -3 Goldfish (with big fleshy brain type heads)
        – 1 Large one about 4inch
        – 1 Medium 1in
        – 1 Small about 1/2 inch

        -1 Albino Goldfish Large abt 3in

        1- Janitor Fish, Small about 1in

        Now, i know we have too many fish in our tank but they all have ich i think
        I noticed the white spots on one of my black moor fish at first, i brought it to my mom’s attention but we didn’t look into it too much. It’s been about a week and our biggest moor fish (Bubby) is covered in a white milky film and was sitting at the bottom of the tank all day. Slowly we noticed that all the fish had the white patchy milky film. The other medium black moor (Mr. Wiggles). Mr. Wiggles is very active but lately hes been hiding at the back of the tank. We change and treat the water often and have a filter. The water is always cloudy though. I dont know if the salt method would work for all our fish… What do i do?

      Hi there Alex,

      Yes – when you do those water changes, be sure to replace the salt so your concentration stays at the 0.3% ratio. Just make sure to dissolve it first before adding it into the water so you do not burn your fish’s skin!

        Hi I have a 5 gallon tank and my goldfish recently just caught ich. I have been using aquarium salt and ich medication to help the problem I have also been raising the temperature the only thing in his tank is his little house he goes in. I keep noticing that the ich will go away then come back in the same spot I keep looking up ways to help him faster so I could clean the tank and put my other fish in but they seem dangerous I basically did everything that was asked of me to help him I get really worried are there any tips that you could give ?

          My first tip is to get him into a larger container. A 5 gallon tank isn’t stable enough to provide a safe home for a goldfish, let alone to conduct treatment in. He will do much better given more space as his immune system won’t be so stressed.

      With enough oxygen and perfect water quality, goldfish can actually tolerate temperatures up into the 90s (F). It will be fine to crank up the heater to 78 or so while treating ich =)

    • Pure Goldfish June 2, 2015 at 2:21 pm - Reply

      Hi mk, sorry for your loss. Ich is kind of a “red flag” disease that means something already isn’t right in the tank. What size tank do you have and how often did you change the water? It could be that your water quality wasn’t where it should have been when you started treatment…

  5. Gabe Varns June 3, 2015 at 2:24 am - Reply

    After the 3 days of treatment, do you just let the tank sit for the 7-14 days or until the tank is cured replacing salt with water changes, or do you repeat the 3-day cycle?

    • Pure Goldfish June 3, 2015 at 3:06 pm - Reply

      No, you do not repeat the 3 day cycle; just keep the salt at the .3% concentration by replacing it during water changes until the fish have been cured.

    Hi, I have just this morning discovered white spot on most of my fish. I have a large tank, 6foot X 2foot x 1 1/2 foot, with about 18 freshwater fish in it. (mostly goldfish). My 16 year old goldfish died yesterday, and I woke up this morning to find alot more laying on the bottom of the tank. Then I spotted the white spot…. I have set up my much smaller tank and have put all of my fish in that… And will treat in that tank.. As for my big tank, if I completely empty it of everything and dry it out, how long would I have to leave it before I can refill and put my fish back in the big tank?

    • Pure Goldfish September 9, 2015 at 5:01 pm - Reply

      I would recommend treating the big tank with all of the fish in it. Ich can survive out of water unless it is sterilized/treated. It will also be easier to keep the water parameters stable.

    Hi, I have one gold fish in a 30 gallon tank. My gold fish’s mouth is moving constant and he/she seems to just stay at the bottom of the tank. His head has also been turning black. I have taken half the water out of the tank, I treated it with a fungus treatment. Nothing seems to be helping him. We have had him for 7 years. I am not sure where to go from here. Any advice would be appreciated. Thanks

    • Pure Goldfish September 10, 2015 at 3:39 pm - Reply

      Those are signs of ammonia poisoning. Please test the water for ammonia right away and do a large water change – take out 50% of the water and replace it with fresh treated tap water. Don’t worry about the fungus treatment, your fish is most likely having issues with water quality not disease.

            Hi, I took out over half the water. The water test was normal. My little buddy is swimming more but his mouth is still constantly moving. Is this normal and if so, how long will it take to get him healthy again? Also will his head ever return to orange or will it stay black?

            • Pure Goldfish September 12, 2015 at 2:25 pm - Reply

              Usually that indicates stress. If the water stays pristine he should return to normal and the black should go away with time.

      Not sure about other types of fish, they might be more sensitive to salinity than goldfish. I don’t recommend keeping them all together anyway, so it may be best to separate them into two tanks during treatment.

    I discovered my fish have ich and got the stuff in the bottle to treat it this evening. I have a 10 gallon tank with 4 goldfish… Also realized I haven’t cleaned the tank since I set it up 4-5 weeks ago. I’ve changed some water but not a cleaning of rocks. I do have the vacuum thing. I changed 50% of the water this afternoon. My heater is the kind that goes on and off on its own based on temp. I’m scared they won’t make it??

    • Pure Goldfish September 15, 2015 at 3:00 am - Reply

      Well, if you want my opinion here’s what I’d do:

      1) Upgrade the tank asap. It is too small for 4 fish; I recommend at least 10 gallons per double-tail goldfish.
      2) Remove any rocks or gravel at the bottom. They trap debris.
      3) Keep changing 50% of the water with the vacuum every day until you get a larger tank. Re-dose with your medicine each time.

      May be, but you would have to test the water first to see if there is ammonia. It can cause that symptom in later stages of ammonia poisoning.

    Hello! Thank you for upkeeping such an awesome website! I have a black moor (bubbles) who has ich. I was just wanting to clarify the best way to treat it with aquarium salt as I don’t like to use chemicals and don’t currently have non-iodized salt on hand. On this page it says to
    “Dissolve 1 tsp of non-iodized sea salt (available from most convenience
    stores) in a cup full of tank water. Pour slowly around the tank, and
    repeat every 12 hours for three days. This will ensure that a 0.3%
    solution is maintained. Between each treatment, perform a 25% water
    change to remove fallen packets of the ich parasite from the bottom of
    the tank.”

    Whereas on the goldfish illness page it says “3 tablespoons of salt per gallon should be added to the water to kill
    the ich. The salt should be non-iodized, natural sea salt or aquarium
    salt. Pre-dissolve the salt in a cup of tank water, stirring it until
    most of the grains can no longer be seen. Pour the treatment around the
    tank slowly until the cup is empty.”

    Which method is the best and if I have a 38gal. tank is the first method only 1 tsp for the entire tank per 12 hours?
    Sorry for the long post, I have had him for over two years now and have never had any health issues with him and I just want to make sure I get it right. I am purchasing some more test strips after work today so I can make sure my levels aren’t out of whack either.

    I’m fairly certain my goldfish, Marlo, has ich…last night she started violently flashing & jumping, then she was rubbing against the filter. Now she’s just lethargically floating upside between the filter and the cords. Last night we changed all the water & this morning I did the sea salt water treatment. I know I need to slowly bring the water temp up, but don’t have a thermometer & am not sure how to safely do it. I’m so worried that I didn’t catch the ich in time…I don’t want her to die.

    I am not sure if my fish have ich or a fungus or something else. I have a black moor and a calico oranda in a 20 gallon tank (both are about 1 inch long). This is their quarantine tank. I got them exactly two weeks ago today and all of their water parameters are fine including ammonia, nitrates, and nitrites. They have great water quality. The temperature is about 72 degrees and I haven’t seen any flashing or darting. The black moor started acting lethargic and bottom sitting a couple of days ago and is now becoming covered in a milky white film (could this be excess slime coat?) and his fins are starting to become shredded. The oranda was fine until yesterday when he started bottom sitting. He looks like he might have white spots but it is hard to tell because of his calico color. Does anyone have a recommendations? Thanks!

    I just noticed white spots on my fish, I believe it ich, I bought some Natural sea salt I was going to try first, but I wanted to make sure I am doing it right. I take out 1 cup of tank water and dissolve 1 tsp of sea salt in that and then pour it back into the tank? is that the right amount for a 40 gallon tank? what exactly should I do first? I don’t have a heater, do you think it is possible to treat without raising the temp?

    • Pure Goldfish October 24, 2015 at 3:09 am - Reply

      For a 40 gallon tank you would use 40 tsp, because it is supposed to be 1 tsp per gallon. I’m sorry I didn’t define the tank size/ salt ratio… I need to update this article!

      The heater only speeds up the life cycle of ich, it doesn’t kill it, so yes, it is possible to treat without the heater it will just take longer to do so. But probably it is a good idea to keep your water quality as pure as possible.

    I have a 30 gallon tank with 2 small goldfish and 3 larger goldfish I have had them for over 5 years with no health problems and two apartment moves under their belt. I recently went to get a Pleco and came home with a another goldfish named gunner. I just noticed this am that one of the larger goldfish has white spots on his tail as well as one of the smaller fish. I have checked the levels and everything is fine. I recently did a water change when I had gotten the new fish. Could it have come from him even though he looks fine? They all seem to be normal as of now. I just want to be sure I’m understanding the directions correctly or can you specify the directions for my tank. I do not have a heater. Do I take the pleco out? What about the airator dragon I have?

    We are treating our goldfish for ich & are having some horrible results. We did just as you said but now their fins are fraying and they’re getting what appears to be blood spots all over them. Please help!

      Hey Nate, if your water quality isn’t maintained during treatment or was bad to start with than you can encounter these issues. Did you test the water for ammonia, nitrite, nitrate and pH before beginning treatment and regularly change the water during treatment?

    Arizona is not particularly known for its water quality but it’s what they’ve lived in for the last year! We had just changed the water the day before we noticed the ich & their behavior was normal. They look like death now! Should I discontinue the salt treatment or is this the “worse before they get better?”

      The areas of water quality that matter most to goldfish are ammonia, nitrite, nitrate and pH. It’s not advised to begin any kind of treatment program unless you are sure your water where it should be for those levels, which is determined through testing beforehand and all throughout the course of treatment. That is because medications (even the natural ones) all stress goldfish to some extent, which makes it harder for them to cope with the presence of toxins in the system itself. When you add salinity to a system that is off-balance it can tip things over the edge. Hope this helps! =)

    I am still confused especially after reading other peoples posts. I am pretty sure one of my gold fish has ick. I have a 5 gallon tank and from what I understand I do a 50 % water change and than take 1 cup of water from the tank and mix in 5 tsp. Of sea salt. Than every 12 hours I do a 25% water change but than after I refill the 25 % of the water do I take out a cup of tank water and put in another 5 tsp. Salt with it and keep doing that every 12 hours or how much salt would I add with the 25% water changes. I will be doing this without raising the temperature so how many days will I need to do this for? Also am I still able to use the water conditioner for chlorine with each water change? Also when I am doing the water changes and I am using the vaccuum do I did to wash the vaccuum or other equipment after each time?

    • Pure Goldfish
      Pure Goldfish January 18, 2016 at 11:52 pm - Reply

      Whatever percentage of water you take out that is how much you need to replenish, so if you take out 25% of water out of a 5 gallon tank then you would need to put 25% of a tsp back in when you refill the tank. 25% of 5 tsp = 1/4 tsp X 5 = 1 1/4 tsp. You would need to double the time without raising the temp. Yes, you can and must use water conditioner. And I would definitely sterilize equipment in between each water change. As a side note I would mention that the small size of a 5 gallon tank makes it subject to large fluctuations in water quality and doing any kind of a treatment in such a space is a bit risky. Also, there is a chance that your goldfish does not have ich but rather an immune response to bad water conditions. You will want to be sure of this before making a decision. Hope that helps explain things better! 🙂

      Could be ich, Josh. White spots are the goldfish’s immune system reacting to something, which is might very well be a parasite if you just got the fish from the pet store. Frankly I would wait and see if more appear before doing anything, and in the meantime try to keep the water as good as possible.

      Hey Ray! Not sure about the catfish, but its really important not to pursue any kind of treatment before making sure the water quality is good, and with 10 fish in a 50 gallon you are definitely looking at a bad water quality situation unless you do 90% water changes daily. Many if not all symptoms of water poisoning can mimic diseases, and medications will only whack things out more if that’s the case…

    I have 2 goldfish in a 5 gallon tank. 1 starting showing signs of cloudy/pop eye. Went to Petco and they recommended Melafix. Been treating with that since Friday (2/19). Did not know I had to remove the filter, it said remove carbon. What do I know. Since yesterday the filter is gone, light is off. Cloudy eye is gone but my poor goldfish’s head has white spots. There is 1 spot by his gill that was white and now has turned red. Melafix helped his eyes, no longer cloudy but the white stuff is still hanging around. The other fish is fine. Don’t know what to do. I am halfway through the Melafix and it seems somewhat helpful but not for the white ich. Please help and thank you in advance for any assistance, much appreciated. 3 days left for Melafix. Petco said I could keep treating with Melafix as long as I needed to. Just don’t know if that’s the best move.

      It’s a bit late now, but I always say don’t treat unless you know the water quality is good. With 2 fish in a 5 gallon tank that’s highly unlikely. Melafix is not going to get to the root of the problem; focus instead on clean water. Please get your fish a bigger tank as this will help you and them 🙂

    Hi Pure Goldfish,

    Thank you for the prompt reply. I did test the water before beginning any treatment at Petco and they said it was fine. We got the first fish at my daughter’s school, she won it at a game last October. I was very leery but hopeful that we could give the fish a good home. Have no experience but definitely did a lot of research, care greatly and have the heart to give it our all. This fish was in a 2-1/2 gallon alone since January. We added the second goldfish then, we did not add any water from the tank at Petco. Just thought our pet Flash wanted a buddy. A week later we got them a bigger tank=5 gallon. That’s when our first fish starting showing signs of cloudy eye/ich. The water was clean. Not sure what the exact culprit was/is. I have been doing small water changes everyday. Melafix is not helping the white cloudy stuff on Flash’s head. I will focus on clean water since the treatment is almost over. I hope that alone with help his condition. So I should not pursue any other ich treatments? Thank you so much for your tips. Have a great day:).

      You’re welcome! No, I would not go for any treatments, right now you have an overcrowded tank in which the main danger is water poisoning. Daily water changes are good – the larger the better – until you can get them more space. And you have a good one 🙂

    Hi Pure Goldfish,

    Happy Thursday to you. I am not so sure Flash has ich. I was doing more research today and I read that ich usually affects a fish’s entire body. Our fish’s head is mainly affected and its mostly this cloudy looking puffy white stuff on top of his head. Not white dots. He has 1 white dot above his left gill. I did a 40% water change this AM. I will see about getting a bigger tank, if space permits. So now I am thinking my fish may have a fungus of some sort. Do you think this may be the case? The white stuff has definitely increased in the last few weeks even though my fish is acting better (moving around more, eating better). Just clueless and our family is stressed out. Any feedback is appreciated.

    Thank you.

      Probably not fungus, it sounds like an immune response. Keep changing the water and it’s good you are looking into a bigger tank, small tanks are stressful on fish and owners. Be sure not to overfeed.

    Hi, I’ve had my fish for a month now. I do 100% water changes every week. I keep a temperature at 78 degrees. I have one fantail about an inch, I have one that I am not quite sure what it is. It’s long about 2 inches, its orange. They are in a 10 gallon tank, they have 3 fake plants, gravel. I have a heater and a tetra PP 10 filter. The fishes don’t fight. When I got the 2 inch fish he had colors of orange and black. Now my fantail has black spots around his body, he sometimes swimming backwards when he is close to the filter, he swins fine away from it. Is this normal? Now for the Ich, my big fish he has at least 8 very small white spots. I do have a LED light. I am very concerned about it. Thanks.

      Hi Kejdi! The black spots are a sign of ammonia poisoning. You have a problem with your water quality because of the space given per fish, the tank is undersized.

    I’ve read through the 4 step anti-Ich treatment and all the comments and still I’m confused. I have a 10 gal tank with 2 garden variety goldfish. I’ve been doing the 4 step treatment using 1 tsp of salt every 12 hours with a 25% water change. Is it just 1 tsp or should that be 1 tsp per gal? Thank you for the clarification and the helpful website.

      It is 1 tsp per gallon. However, if you have more than one fish in a 10 gallon tank I would not recommend executing any kind of treatment, as the water parameters are too unstable.

          And, what size is the tank? Do you have gravel and/or filtration? Ammonia is the most important parameter to know; you may want to have it tested by your LFS. Either way I would change the water again today and keep changing it; 1/4 per week isn’t enough in most cases.

              For the size of tank you have, you would need to do at least 2 water changes weekly to accommodate your stocking levels. I would also take out the gravel, as it is a trap for debris and likely leaching toxins into the tank. Ich is a signal that something isn’t right with their environment.

We have a black oranda ( head to end of tail is 6 1/2 inches) and a small Ryukin (head to end of tail) in a 20 gallon top fin tank… We have been fighting high ammonia in the tank…. Now due to all the stress of trying control the ammonia we have ich… I’m in the third day of treating the ich and the tank is cloudy… I mean very cloudy… Like a London fog… My gut say it’s a major bacteria Blume…. We had to pull the carbon filters for the ICH Guard medication…. I have also treated the tank with aquarium salt…. The fish are improving, meaning they no longer lay at the bottom of the tank…. I read that the ich would get worse before it gets better…. And it has… The oranda jus had a few spots yesterday now he has tons…. Should I be concerned about how cloudy the water is becoming???

I also replace the salt treatment that is removed by the water change… Also I am raising the water temp to the low 80s… The carbon filters are still out due to the meds… The fish are more active and less fin clamping… But the still look pitiful with the ich all over them… Is there no other way to assist clearing up the water???

      It’s a myth that large water changes cause stress, unless the nitrates are high. Cloudiness in any form signals a dirty tank, and yes, only water changes will clear it up.

    I bought 3 goldfishes a month ago and one of them died unexpectedly last night. I had just gone to pets at home to buy the white spot treatment. (we believe that is what they have) but I was too late.

    We treated the tank with the medicine last night and are waiting to see if our other 2 survive. They are laying at the bottom of the tank and not moving much. We also put the recommended amount of salt to see if his would help and left the filter working.

    Our fishes are very small (baby goldfishes) and were told that a 24 litre tank would be ok to start with until they were 6 months old, when we could upgrade it. Was this tank too small even for 3 of them?
    We consulted with someone at the pet store who said that perhaps we overfed them or did too many water changes. We changed 50% of the water every 4 or 5 days as the water was a bit dirty. Is this good or bad? We read so many things but we don’t understand why they are ill when we have tested the water and everything seemed fine.

    I would appreciate if you could let me know.

    Kind regards,

      Yes, 3 fish in that size of tank is way too many. It’s not even enough space for one, the size of the fish is irrelevant because even small goldfish produce a lot of waste. There is no such thing as too many water changes with goldfish 😉 You would need to be doing daily 90% water changes with that many fish to keep them healthy.

Now both the fish have a black spot on their tail fin and one of them has developed tiny white spots on its body. I want to help them. Please advise what i can do to treat them. I am not not sure how may gallons the bowl can accommodate (I think in litres it should be around 10 litres.)

    1) how much sea salt would i need?
    2) SInce there is a problem with the water, should i change the whole water once?
    3) There is no temperature control in my fish bowl.

      1) Don’t use salt or any kind of treatment while water trouble is going on. It will only stress them more.
      2) Yes, daily.
      3) That’s okay. Like I said, you don’t want to do the ich treatment while all this is going on because you could kill both of your fish.

Is it possible to have an ich free tank with no heater? And after this poor little guy dies do I clean the tank treat water with the salt and let it run a couple if weeks or days before I try again? And should I get another filter now?

      Pure Goldfish May 6, 2016 at 4:04 am - Reply

      To be perfectly honest, Selena, 1.5 gallons isn’t enough for even one goldfish 🙁 Fancies need to have at least 10 gallons apiece because with such a tiny water volume, they quickly poison themselves with their waste and will be permanently stunted in their growth (they get to be 6-8 inches large). Ich is only a sign that they are weakened. You don’t need a heater to have an ich-free tank though – goldfish get ich when their immune systems are low with or without it. If you want to keep goldfish I highly recommend getting a 10 gallon min tank with a proper filter and cycling it first too (you will have to read up on that). Hope this helps 🙂

    Hello. I started up a new 46 gal tank and have slowly added in some
    Goldfish. I started with one and after a week everything seemed fine, I added in two more. Everything was good for a few days, then I noticed the first one had what looked to be anchor worm. It was hard to catch beacuse she is shy and hides a lot. By time I figured out what it was and got the medicine it looked as though the anchor worm left (just a protruding red hole or bump left no tail of the worm as I was going to remove it). I removed the carbon from my canister filter, did a 20% water change and added medicine for anchor worm and some salt. Unfortunately, as I did this I noticed my other has white spots. What do I do now as I am not sure how to treat both? They seem healthy otherwise and are not flashing or lethargic.

    Hi there…
    Wonderful information!! Just a quick question… After the 3 days of 25% water changes adding the sea salt how long do you leave this for M before doing another 50% water change?? This is day 2 for me I don’t see much change, not as much flashing going on just more sitting on the bottom of the tank 🙁
    My tank is roughly 228L
    So is that still 1 tbs of salt??

    • Pure Goldfish
      Pure Goldfish May 12, 2016 at 4:07 am - Reply

      1 tsp salt. After the 3 days of treatment wait 12 more hours and then do a 50% water change again. If your water quality wasn’t spot on or there was another underlying issue the treatment won’t yield results.

We emptied the shop water in the tank and haven’t changed it for three weeks because we have a filter and the bottom feeder.I love this fish so much my friend gave it to me and I would be sad to tell her it died please give me a soulution and help me with the salt.(three gallon tank) I have a dog too but that has nothing to do with it I got it after I noticed . Had her for a week I got the dog the day after I noticed.I moved the fish to a smaller tank with clean water we used to keep it in.No filter rocks or plants about a gallon give or take.We had rocks in the big tank too with a nice decoration at least 2inches tall and 3 in with 3 1/2 in length.She also has small strips of brown or black on her tail.I looked up pics of this ich and it looks just like it . please help me !!!

                I wish I would have read this before I did my treatment. I did not read this site but had the knowledge to do exactly what is written in this blog. I got my salt and put it in my tank because my Black Moor Goldfish had it pretty bad. It showed up almost overnight about 10 hours. And when I put the salt in, I noticed the next morning that my two Japanese shrimp we’re dead.:-(

      Your article said if you replace 10 gallon of water, replace with half teaspoon of salt in new water. But Helena was going to put 10 teaspoon of salt in 10 gallon tank, isn’t that too much? Please let me know what is the correct dosage for rich treatment. Thanks.

    Hi, so I had added an algae eater with my goldfish so I know it was the culprit of my fish getting Ick. I didn’t know it was Ick till today when I saw the white spots on its fins and some raised scales plus the sudden darting and lethargic behavior. Is it too late to save them? Is it really better to do the salt treatment versus the medicine? Shall I separate that algae fish or should he be part of the treatment process.

    Thanks for your help!

    Hi, I recently purchased a black moor a couple weeks ago and i just discovered that he had a white slime coat on him.. He just recently got this after i purchased a food block, it was pink and the box stated that it wouldn’t cause the water to fog but i believe it did, it also caused the filter on my tank to turn pink, but I believe that this food block may have caused this slime, my question is though, could you classify this as ich?

      No that doesn’t sounds like ich, ich is spots not slime. White slime is the fish producing too much mucus in response to irritants in the water. Cleaner water should do the trick.

        Good afternoon, Pure Goldfish I have recently purchased a 10 gallon tank with decorations and along I also bought 15 goldfish and 2 alge eaters. The pet store told me I won’t need a heater due to the fact of the fish only needing cold water to live in because it is their environment water but 2 days ago I notice 1 alge Eater and 3 gold fish dead I quickly removed them and set them aside. Today I found 2 more goldfish dead and noticed some white spots on the remaining fish in my tank. I immediately knew there must be something wrong and have been trying to find a solution to help the fish recover and gain strength. I would like to know what can I do to help my fish and not lose them please help me find a solution to cure them

    Hi, we gave started the salt treatment, 1 tsp to 1 cup tank water every 12 hrs for 3 days, now tonight is the 25% water change. We have a 20 gal tank and we are actually removing 3-4 gal. because a lot has evaporated. It’s about a gal short. So I’m confused on how much salt to put back in with this water change to keep it consistant. Please advise. Thank you.

      Pure Goldfish July 3, 2016 at 3:57 am - Reply

      Basically you just have to maintain the concentration per gallon. However, if water is evaporating that technically isn’t removing any salt so you don’t have to put salt in the new water. Hope that makes sense 🙂

    Hello, I just discovered this website and I love the info in it. I have 2 comets in a 20 gallon (they’re being moved to a pond soon) and they are in terrible shape. I had a 2″ pleco and a shubunkin I bought maybe a week ago, but they both died. My fish have never been sick before, but now my remaining fish are in terrible shape. They look like zombies. They both are laying at the bottom of the tank gasping for air. They wont eat. They have hemorrhagic septicemia from the look of their fins (Their red and all tore up, with the edges being white), and they have ulcers around their mouth and gills. Their mucus layer is extremely thick, even on their eyes, which made me think it was velvet at first because it looks that thick and fuzzy. However, if I look really close, it looks like they have little white dots all over their body, which made me think ich. My water parameters checked out to be perfect (it is also cycled, and they have lived in the tank for about a year). I dont think it was from the new fish because one of the older ones was showing signs of lethargy before I got it. The temp of the tank is about 71 degrees. Im currently treating with erythromycin (for the septicemia) and ich guard. I also put about 4 tablespoons of salt in their tank. Ive been treating for about 2 days, but they only seem to be doing worse. Should I do a more aggressive form of treatment, including a salt bath? Or will that be too stressful? Should I add more salt to the main aquarium? I will be turning up the temp and reducing light as much as possible (It shouldnt be too hard, the tan is in the basement). Thanks in advance. These fish really mean a lot to me, and I want them to live to see their new home in the pond.

    • Maleah July 21, 2016 at 6:01 am - Reply

      They also have clamped fins to the extent that they can hardly swim. The disease progressed in a span of about 4-5 days. Before I went on vacation, they were fine. When I came back, they looked horrendous. Hope this info helps

        Hi Maleah! You say the water parameters are perfect… what exactly are they for ammonia, nitrite, nitrate and pH? GH and KH might be good to know too, and what the tank setup is like as far as any gravel, filtration, what your normal water change schedule is like, etc.

        • Maleah July 22, 2016 at 8:01 pm - Reply

          I had taken a sample to my LPS to get it tested. She didn’t tell me what the exact parameters were, she just said they were exactly where they needed to be. I had done a water change as soon as I got home from vacation and that was the water that was tested, so it’s possible the water was not so good while I was away. Both my fish died yesterday. I don’t think the disease was ich because of how bad their condition was in the last day or so. I regret not having any clove oil on hand to end their suffering a little sooner. I’m currently trying to kill any bacteria or parasite that is living in that aquarium, so I put 60 tsp of Epsom salt, turned the temp up to 89 degrees, and covered it up so its not getting any light. Is that going to be sufficient to kill everything? And how long do I have to do it for?

    I have two new goldfish living in a 20 gallon tank. We’ve recently noticed that one of them has become lethargic, spending much of it’s time on/near the bottom of the tank, coming up to feed and play around briefly. It appears that it has ICH (white spots). Can you advise how to go about changing the water and adding the salt solution. We’ve never changed the tank as the fish are very new.

    Hello, sorry to ask again still confused. I just got 3 goldfish from Petsmart yesterday evening. So have had them for about 24 hours. They are the only fish in the 75 gal tank (new set up no prior fish). They looked healthy and clear when i got them now one has 4 white spots on it’s head that wasn’t there yesterday and I notice it hanging at the bottom back of the tank (still eats though). I would take them back but I guess they have already contaminated the whole tank so it wouldn’t do any good… What would be the salt ratio I’m confused would it be 75 tsp since it is a 75 gal tank? That seems like a lot don’t want to kill my new goldfish.

        I had the tank set up and running for a week before getting the fish. I read somewhere else that the only way to “truly” get the tank set up with the bacteria was to get the fish so the cycle could start. But yeah, it was up and running a week with no fish first. I soaked in warm water and rinced off all gravel, fake plants, and decor before putting them in. This morning the one fish that had the 4 white spots doesn’t seem to have them anymore and it is more active. Should I still do the treatment any ways, or wait and watch for more spots? With no heater the tank is running at 79*F. It sure looked like ick but it couldn’t have cleared up that fast on it’s own?

    I’ve recently lost 6 fish in the last 3 days, leaving 1 left. It’s very upsetting being I am a newbie to the fish hobby. I have a 28 gallon tank. Yes, I know it’s little for the amount of fish I had, but that’s what my local fish store sold me. Not knowing anything I went along with it until I started doing research. But now I have one left and I have worked my butt off with this tank to keep all alive. I’ve been looking up exactly what it is that’s going on, and I THINK it’s white spot disease. It started on my artificial plant, white gooey stuff, and now it’s on my fish. Covering his eyes and body and his fins look horrible. Yesterday I did a 75% water change, taking out the plant, and doing a thorough clean. I added aquarium salt and put a heater in my tank raising my temp. Today I did I’m starting your treatment, raised the temp, and added sea salt. I’m curious to know if I’m approaching this correctly by not being certain it is white spot disease? Also when I do my water change, how am I supposed to maintain the temp in the new water to 76 degrees? I appreciate any help you can provide, I don’t want my big guy to die 🙁

    So about 5 weeks ago my 5 goldfish of 2 years, got a new, bigger tank. They settled in just fine, and are loving the extra room, hooray! However about a week and a half ago I noticed a small white dot on one of my fish’s tail. Granted it was rather hard to get a good look at, he never stopped swimming long enough for me to get a real good look. I thought of Ich right away since I have had tanks with it once before, but he didn’t show the other signs. So I passed it off as nothing and decided to just keep an eye on it. Today I noticed that the small white dot has grown and is now a larger raised white dot. So diagnosis, Ich. I am currently slightly over due for a water change by a few days, as a result of an overfull schedule, so that will be the first thing I do tomorrow, I realize that it probably hasn’t helped the situation at all. So my question is that since he is still extremely active, and always has been, eats fine, doesn’t clamp up or anything else (the other fish are fine as well I have thoroughly checked them over) should I just try more frequent water changes for a while, and continue keeping a close eye on the tank, before I try more stressful treatments, such as water temperature and salt?

    I have noticed my little black moor is very lethargic today, sitting on the bottom. Now and again he goes on a mad dash then returns. There are white spots that look like tiny bubbles on his back fins and he looks a bit like he has a very thin sheen over his body. He has been fine until now. There is one other fish in there, a telescope, who seems absolutely fine. It is a 64 litre (14 gallon) tank. Is this ich and should I start the salt treatment or could it be something else. They both have long strings of poop coming out, the telescope is greenish but the moor is a bit whiter. Wondering if maybe all this has been caused by overfeeding or is the Moor suffering from something more serious? cheers

    The other fish is clamping it’s fins and hanging out towards the top of the tank, only moving to eat. And swim fast from time to time and then back to it’s spot.

    I have decided to try a salt treatment for 7 days with daily water changes.

    I have a heater for my tank and would like to get the temperature up to around 74 degrees fahrenheit since that si what is recommended. But I also know that fast temp changes can cause stress and more issues. How fast should I bring the temperature up?

    Thank you for your help. And any other insights you think I should know.

    1. right, I see how the white cotton growth and eye cloud might be a fungus. But I also have a fish in the tank that is shaking her head and swimming fast in short blasts. Can fungus also cause that behavior?

    2. And I see the water shouldn’t be too cold to treat the fungus. I have heater. I have never used it before. If I am at 68.5 degrees. Over how long of period of time should I take to get the temp up to 75 degrees. I know it can’t be cold for the salt to work. I just don’t want to bring up the temp too quickly. Like should I raise it over the next couple of hours or over 24 hours. what is safe for the fish. I know temp changes cause big stress for them.

    thanks Pure Goldfish.

    How should I go about replace the water. .. I have pebbles at the bottom of my tank and they get really dirty because of the food and waste. Should I take the fish out everytime I replace half the water to clean the pebbles or should I just take all the stuff out of the tank. I just don’t know how to keep the tank as clean as possible.

    Hey a couple of weeks ago I bought 3 gold fish.One was very small and the others were average sized. I have plants and other fish tunnels and things.but soon after I bought them something was wrong. The really small fish started to get white spots on the end of its tail and the tail was starting to disappear.i left it till the next day and its tail was just being eaten away. I had no idea what to do so I put it in a separate tank hoping it wouldn’t affect the others. So I kept it in there for a day and half of its tail was gone.It was now really struggling to swim.i knew it was going to die very quickly but then… my other goldfish started to get the spots on the end of his tail! Please I really need some advice what to do quick! How do I stop the white spots from killing my fish! I would also like to ask if I treated the deseise would there fins grow back?

    Hi! I have a 70 gallon tank with 3 orandas and a ranchu. Recently my ranchu has become very lethargic and barely eats. This morning I noticed he had some white spots on him, but the other 3 fish are all fine. The other fish have also started bullying him practically non-stop (chasing him and nipping) Is this because he is sick? Can ich only affect one fish but not the others? Also, I have had the tank setup for about 9 weeks, not sure if that info helps anything or not. Would you recommend the salt treatment or perhaps just a water change? Should I separate the ranchu from the others? Really don’t want him to die, I love the little guy.

    • Hannah March 25, 2017 at 2:58 pm - Reply

      I’m not an expert, but I would definitely put the ranchu in a separate tank, at least until the white spots are taken care of.
      As for the chasing and nipping, they might be trying to play (after all, what else are fish supposed to do xD), or they might be purposefully bullying him, which is, unfortunately, common among fish of different breeds.
      Maybe a tank divider would help?

      Best of luck

    Hi there!
    I recently got two comet goldfish (one was a carnival fish that I rescued, the other a pet store fish), both seemed to be in good health. I purchased a 20 gallon TopFin tank, complete with a heater, filter and LED lights. Since I’ve only had the fish for about 3 weeks, I have not had the chance to change the (purified) water yet.
    This morning I noticed that my store-bought goldfish had developed small white spots on his (not sure about gender, but I’m taking an educated guess here xD) dorsal fin and tail. The other fish seems to be fine, although she is mostly white so it is harder to tell. Both fish are behaving normally and eating as usual. I have a small quarantine tank already prepared, what should I do?

    I should also mention that yesterday I moved the tank to a 3-foot stand and had to temporarily remove about 50% of the tank water to lift it. After moving the tank I put the same water back in. Should I run my gravel vacuum, or would that only make it worse?

    Help I’ve had a black pop eyed goldfish for about 3 yrs. He was getting really really big in a 10gal tank. Never had any problems and didn’t know a lot about fish. We got a 55 gallon tank about 2months ago. I did not cycle the tank not knowing I should have. Well we got a pleco aka Algae eater a few days later from petsmart. The next day afrter getting him I noticed his fins were ragged looking & blood spot on the bottom of his belly. The very next morning he was dead. So we took him back got another from walmart. Everything seemed fine. Until about 3 weeks ago I noticed my black goldfish had while coming on his tail & like he had been trying to scratch his self. Plus there was cotton white stuff on the trees and in the gravel. So we invested in a API freshwater kit. First thing the ammonia was extremley high 4.0-8.0ppm PH 6.0 Nitrite 1.0-2.0ppm Nitrate10-20ppm. So I got a vacum started doing that done a 50% water change and put api Ammo lock in it. Few days later same thing. Constantly trying to scratch himself and been at the top of the tank for 3days straight. At this point I’ve been doing a 25% water change everyday for a week Long story short I noticed my goldfish had white spots on his front fins and around hiseyes. So I started rapid cure ICH treatment. Worried sick about him and not knowing much about fish at all.. Tonight I noticed a long string hanging from my pleco and then what looked like blood dripping from him??? We got him out asap put him in a 5gl tank. He looks so pale now! Have a killed him??? And what do I do to help both fish? I’m so lost and scared for both fish

    Doing a 90% change between each treatment, does that mean one per day? Or one every 12 hours?

      If the large goldfish came in contact with contaminated water from the new goldfish, that is probably how that got transmitted. Ich can even survive out of water, so equipment can carry the disease around.

    I’m not totally for sure if my gold fish has ich or something else. It’s in a 20 gallon tank with another gold fish. We also had algae eater up until yesterday night .( it died) the gold fish was acting weird yesterday morning before I went to work not being as active as normal. I noticed last night that when I came home that it had more like dandruff looking flakes on its tail. It’s just been sitting at the bottom of the tank. I had only had the algae eater for two weeks. So I don’t know if that had something to do with why my gold fish is now having problems. The other one seems to be just fine.

    Hello, I have 2, 2 inch black moors, 2, 2 inch red orandas, and 4, 2 inch common koi in a 55 gallon. One black moor appears to have very, very small white spots on him. He is swimming and eating fine. No one else has anything and all are swimming fine. Is this ich at its beginning stage or something else? Any help would br greatly appreciated!

      It definitely could be, but it might also be due to stress. Koi shouldn’t be kept with goldies because they get so huge and can be aggressive to them.

    I moved my 2 goldfish to a 10 gallon tank yesterday afternoon (they were in a 1 gallon tank. I know they should be in at least a 30 but for right now they are in a 10) and the one appears to have developed a white spot on his tail. He is acting fine, actually much more active since he has more room. As of right now the other one does not have an spots on him. I tested my water before putting them in and it was good. Could he really have developed a spot in 1 day? I don’t know what to do

    Hello. I have had goldfish for quiet some time now. I started noticing white spots on one of my goldfish and instantly googled it online. I found out that this was Ich and started treating it. It went on for about 2-3 weeks before the ich was gone. I had to move, so I took my aquarium with me, and now it seems that the ich has returned as now one of my goldfish seem to have their whole tail ripped open by the ich. ( Worse then the first time!!!) It is way to expensive to keep buying medicine for ich and I don`t know what to do anymore. I followed the recipe above last time, but it seems that the ich returned. Please tell me what I could do.

    My parameters are all normal, PH is normal etc.
    I do once a month/twice a month small water changes + water conditioner to protect my fish against tap water. (As I have a big tank/ a big filter I don`t need to do more then 20% twice a month.)
    I have had fish for over 2 years, and only recently having problems with this.
    I also did not have any plants in my tank when the ich returned.

    I have 3 very small goldfish. We’ve had them for only a couple of weeks. I was told 1 1/2 gallon tank was enough. I just noticed 2 of them have these white spots. Is the tank too small? I also was not told to not dump the water from the store into the tank with the fish. This is all new to me. I was just trying to put something nice together for my 4 year old son who got a free goldfish from a festival. I bought a small aquarium kit and 2 other fish for $ .19. They have been a joy to watch, but now this. I didn’t want to deal with a heater. I was told goldfish were resilient. I am using distilled water and I rinsed everything in the tank in warm water before use.

      Yes, Joyce, the tank is far too small. Ich means the fish are very stressed, but you can’t treat them in that size of a tank without a big risk, because there is probably very high ammonia in their water. A heater isn’t a must but it speeds up the treatment process.

    I have two goldfish that are pretty good size I have had for a year and I brought an algea eater last weekend and put in the tank but didn’t realize I was not supposed to dump water they came in in the tank. Well now I noticed red spots on my gold fish and in one day they look like they got a white film on them. They lay on the bottom of the tank. I brought E.M. Erythromycin and put in their tank today. Can you tell me what they have?

      Red spots can have more than one cause, Tana. It could be high nitrite or ammonia levels in the tank. It could also be a response to parasites. The first step would be to test your water, and figure out if that is what is wrong first.

    One of my four finned goldfish looks like it one of it’s tails is not there. It definitely has Itch, as there is one small fuzzy speck on it’s tail. I will start treatment tomorrow. It does not seem to have a problem swimming, though. I have not found a tail in the tank when I do my weekly cleaning. Could it have lost it because of itch?

      Is the tail shredded, or rotted away? Usually a missing tail is from very high ammonia levels. For ich, you want to treat for 14 days. However one small white speck might not necessarily be ich, but an immune response to the tank environment – I’d test the water if I were you first.

      • Angie October 2, 2017 at 2:20 pm - Reply

        Thanks for the reply! The tail doesn’t look shredded or rotted, but looks like it’s underdeveloped on that side, like its malformed. I use Prime conditioner, which says it detoxifies ammonia, nitrate, and nitrite. It might be a bit old, or I’m not using enough. I’ll instead buy a test kit for now. Thanks!

    I noticed this morning my black moor goldfish had a white spot on his head. I have a 55 gal tank with 6 medium sized goldish (although they are not juveniles as I had them for about four years, but they are about 2 inches long without their long flowing tails). Last week I bought the sixth one and I added him without quarantine, but he looks healthy. They all do. Two weeks ago I completely cleaned and replaced the substrate from sand to gravel. So I am not sure what caused the issue. It seems like ich, as it seems similar to an outbreak I had 3 years ago. I treated it that time with some blue liquid. Having a 55 gal tank doing 90 percent water changes seem like a lot of work. Should I purchase a 10 gal tank and move them all there and treat that instead? or should I just treat the black moor on its own? Please help.

    Hello, I have a 20 gallon tank with 4 goldfishes (two comet, one common, one black moor) and 2 pleco (albino brittlenose, and just a normal black one), and three of my goldfish have developed white spots all over them. Normally they get white breeding spots at this time of year, but I think it’s Ich because they have been acting weirdly (hiding, laying down at the bottom), but they still have a healthy appetite and are eating (I just feed them broccoli). Do you think that’s the case? If so, how do you suppose I should treat it? My extra tank has recently started leaking, so I don’t have anywhere to put my plecos. I also don’t have a heater, to raise the temperature. Do you think I need a heater? My tank temperature is around 73 degrees Fahrenheit. I’ve tested my water and the nitrate and nitrite are in the safe zone. Thank you.

    Thank you for your website. It has been so helpful. We have a 55g with four comet goldfish. They have had very few problems over the two years that we have been raising them. Recently, we added two fish that the pet store said are helpful in eating algae since we have had recent issues with algae. These fish have whiskers and are black and gray with stripey like designs (not sure of name). Three days after adding them, our fish had white spots all over them. (We are sure it is ich). We raised the temp over 3 days time to 84 degrees and added aquarium salt. They do not look better at all. Day 4 and they are all bleeding all over…not just fins and belly. They are eating and swim to eat but the rest of the time they are on the bottom breathing rapidly away from the heater. What are we missing? We did a water change (four days ago) and will do another one tomorrow. 50 percent water change. I do not know the amm. or nit, numbers at this moment. Please help!

    I wanted to thank you very much for this blog and all of your responses! My 3 baby butterfly koi, goldfish, fancy goldfish, and pleco ALL survived ick thanks to you!!!

    I removed all unnecessary decorations and substrate, rinsed it all with hot tap water, and let it air dry for the duration of the treatment. I started with 80% water changes every 12 hours for the first 4 or 5 days then dropped back to about 70% every 24 hours for about 10 more days to make sure. I treated the pleco in a separate container with a bit less salt since they are more salt sensitive (same water change %’s and schedule)

    I don’t understand the hundreds of confused comments from people about the 1 tsp to 1 gallon dosage of kosher or aquarium salt… if you remove 5 gallons during water change you add 5 tsp to the replacement water … if you remove 500 gallons during the water change then you add 500 tsp to the replacement water. And the initial salt treatment (before there is any salt on the tank) you add the same number of teaspoons as there are gallons in the tank. Always maintaining the 1 tsp per 1 gallon ratio. It made perfect sense to me. But I understand the panic you feel when you are just trying to take action and love your fish!

    Anyway many MANY thanks from Spot, Spike, Mrs. Pearl, Mello Yellow, Pure Goldfish, and Mr. Pleco

    I recently used tetra lifeguard tablet treatment to ensure that my new oranda didn’t have anything when I put it in my main aquarium. turns out that the tablets seem to have stressed the fish to the point it got a very bad case of ich. it got to the point that the poor oranda was covered in white dots from a completely covered tail with now blood streaks, fins and wen. the fish went from a large number of spots only on its tail to whole body with bloody streaks in tail in 4 days. after the tablets I did a large water change and used aquarium salt and tht didn’t do much, so I tried “super ich cure” from pet smart and that only stressed the poor guy further and more spots appeared …so now I’m back to aquarium salt only and hes a bit better, gave him a 5 min salt bath as was recormended when I researching ich cures. is there anything I can do that will ensure the ich will go away?

    Hi PG, I have had a juvenile (6cm) fancy goldfish since July but which developed ich after I added a 2cm bristlenosed pleco to it’s tank (qubie 40 approx 45L) a fortnight ago. I test the water regularly and do 25% water change, feed a spinach leaf and 4 Tetra Goldfish Gold Japan (premium fish food for fancy goldfish) pellets twice a day, occasionally peas or frozen daphnia/bloodworm. Worried about oxygenation I have superfish aquaflow 100 and 200 (swapped out active carbon for poly filter fibre) and 2 airstones. Only fake plants, marina aquarium gravel. I raised the temp and added API aquarium salt at the rate you recommend, the white spots disappeared but he began to stay at that bottom of the tank, fins clamped for longer and longer periods, now some reddening has appeared between stomach and anus and he swims erratically, often seeming to be startled from lethargy to feed and sometimes dives repeatedly in the airstone bubbles. I have been changing 15L of water (adding the salt still) for 2 days now but worried perhaps there’s something else I can do to help him. Pleco is fine munching on a piece of screwcumber a night…

Can I reintroduce my two fish to the tank, if I wait a while for the salt to dissolve, or will it still burn them if I put them back?

      You can stir the salt around in the tank and it will dissolve pretty quickly, then you can reintroduce them in 🙂

    Hi Pure Fish, My Orandas’ have a problem of which I have no good solution. I’ve lost 7 of my 9 fish, the remaining calico appears to be losing its scales and the fins appear to be tearing, the remaining black appears to have a light gray film over his body and a small white spot rising from its head. I’ve emptied the tanks water the tank is 29 gals, changed and thoroughly scrubbed the filter system, the temp is usually 78 degrees, scrubbed the decorative plants, treated the water with Stress Coat and Ich solution. I had purchased small relatively young fish and over the last year they had really blossomed into beautiful large fish. I’ve removed the remaining two placed them in individual containers treated the water, they survived the night but neither is eating today. Do you have any suggestions.

      You are probably dealing with some parasite, it may not be ich though. There are lots of parasites that cause those symptoms. It sounds like whatever it is is a quick killer, may be costia. I would use MinnFinn and order it asap.

    I have a 20 gallon tank with a gold fish and a algea eater they have white spots on both them. So I change put most of the water then fill it using a conditioner for city water then use 20 tsp of salt and do it for 3 days.

      It will probably take longer than three days for things to resolve fully, but you’re on the right track.
