I think you’ll agree with me when I say:
“Goldfish are so awesome.”
And if you didn’t know how many eggs a goldfish can lay before…
… it will blow your mind!
I guarantee you’ll have a new respect for your female fishy friend after reading this 🙂
A Bit About Goldfish Eggs (and How to Take Care of them)
So, exactly what do goldfish eggs look like?
Healthy goldfish eggs look like small, clear bubbles and can range in color from white to yellow-orange.
Here are what about 125 freshly-laid goldfish eggs look like:
They are also EXTREMELY sticky.
Of course, this is part of their survival strategy.
By clinging to the plants as they would fall to the bottom, they have a better chance of not being devoured.
That’s why breeders put “spawning mops” in their tanks. Usually these are made of yarn and the eggs stick to them instead.
If you want to tell if the eggs are fertilized, you can look for tiny black specks in the eggs after the two or three days or so.
Those are the eyes of the tiny fry developing inside 🙂
This is a 3 day old (fertilized) goldfish egg:
(Isn’t that the cutest thing you’ve ever seen?!)
And a sibling… (who kind of looks like a frog)…
Now:
How long does it take for them to hatch?
In 4 to 7 days, the eggs hatch (depending on the temperature).
That is – unless fungus has taken over and killed them before they had a chance. 🙁
Fighting Fish Egg Fungus
Fungus will grow on unfertilized eggs.
It can also spread and infect the fertilized ones.
Yikes!
A 2 day old goldfish egg attacked with fungus under a microscope:
There are some things to do about this.
Now:
Some people add a medication that turns the water blue to prevent fungus from taking hold…
But personally I wouldn’t do that.
Some find a higher rate of defects in fry from eggs that have been soaked in methylene blue.
I have found when it comes to fungus, nothing is as good as MinnFinn.
The active ingredient (peracetic acid) is used in catfish hatcheries to stop the fungus from ruining the eggs – in a safer, more natural way than harsh chemical treatments.
I treat my eggs with regular strength 1 hour long bath.
Doing this 1-2x every day is a good idea.
As far as other methods go:
You can add shrimp to the tank (cherry shrimp, ghost shrimp or others).
They know how to pick out the bad eggs and eat them – but they don’t mess with the good ones.
Think of them as nature’s babysitters 😉
Ramshorn snails are also excellent fungus-eating egg companions.
I have also used Colloidal silver and Microbe-Lift Artemiss as leave-in baths to help keep fertilized eggs fungus-free.
No issues mixing them with MinnFinn treatments either. 🙂
And remember:
The condition of the water is REALLY important when it comes to successfully hatching them.
Clean water with plenty of aeration will help to prevent fungus, as well as removing infertile eggs right away (which will spread the fungus).
Water changes 1-2x per day is usually a good idea.
If you don’t have live plants in the water, a small sponge filter is a good idea.
Hatching Time
Here’s a 1-day old newly hatched fry:
They spend a couple of days hanging out on the sides of the tank…
… And occasionally, trying to learn how to swim.
(Cute, right?)
They feed off of their egg sack until they are ready for their first meal in another 2 days – no point in feeding them before then. 🙂
When the eggs hatch, if there are more than 300 you probably need to perform a water change as the contents can foul the water.
The tiny little wriggling creatures that emerge look like some kind of strange insect.
They start looking a little more like actual goldfish as they get older, usually in several weeks to a couple of months.
The hungry fry will demand a lot of food as they grow!
Once full grown, it all starts over again.

Just How Does a Goldfish Lay Eggs (And How Many)?
Let’s set the record straight:
A female goldfish can never be pregnant. (Read why here.)
But she can swell up with the eggs, and even perish from a condition called egg-binding if things get complicated and a male doesn’t spawn with her.
So yes, goldfish do lay eggs – and they can lay a whole bunch of them.
In fact:
How many babies she will have depends on her age and how much she’s been eating…
But a goldfish can easily lay over 1,000 eggs at one time!
That’s just at one time.
During breeding season, goldfish will often spawn multiple times on a weekly basis.
Talk about a family reunion 😀
So if you miss out on the first spawning and the parents gobble up the unhatched youngsters before you can interfere, don’t feel too bummed – keep a close eye on them for the next week.
Here’s a tip: goldfish usually spawn early in the morning. If you wake up before sunrise, you should be just in time for the show and should be able to separate out any eggs before they get eaten.
(Landing on something removable like plants or a spawning mop really helps.)
Fact:
Like chickens, a female goldfish actually CAN lay eggs without spawning with a male goldfish.
They won’t hatch though.
These infertile eggs usually get eaten up or decompose in the water.
Now:
If she’s ready to spawn, she’ll start releasing pheromones into the water that let the males know it’s time to breed.
They will then chase the female around, nudging her sides until the eggs come out.
As they fall through the water, he’ll fertilize them with his milt.

Safety Warning!
Goldfish make HORRIBLE parents.
They will eat all of their eggs faster than you can dial up Child Protection Services…
… And they will even eat their own newly hatched fry.
Any other bystander goldfish around will happily join in the cannibalistic buffet.
Yikes :O
So if you want to make sure your eggs hatch, they will need to be separated as soon as possible.
What do You Think?
I hope you were amazed by what you learned.
Now I’m turning it over to you.
Have you ever tried to take care of goldfish eggs, or seen any your pond or tank?
Drop your comment below (I love hearing from my readers!)
Seen my goldfish lay in the bath tub I have then in there are lots of weeds in it .dont know if any of the eggs survive just have to wait and see
Very cool, Avalon! Sometimes they hatch, sometimes they don’t.
Hi my fish have played eggs but they are stuck on the pebble hole do I separate them ?
The eggs are sticky, no way to separate once laid without hurting them
When the fry are ready to eat the food what type of food should be given to them ??
Freshly hatched baby brine shrimp or instant baby brine shrimp are really good. Daphnia is also good.
Very informative! I learned a lot from your article. Thanks!
Glad you liked it, Mo! Thank you for your comment! 🙂
So I have a female goldfish and she is about 1’ and I have not gotten a male goldfish yet but when the female lays the eggs and they are fertilized, would it be easier to just take her and the male out and put them in a separate tank?
You could do that for sure.
I guess my goldfish defy the odds. I have a small pond in my back yard and have five 4-6″ goldfish. The water did turn “foamy” for a few days a month or so back, which I heard was a sign of spawning. And I did notice the oldest fish kind of “bullying” the newer fish. But I today I was surprised to find an “extra” fish in the pond, which I accidentally forced out of hiding when I reached in to clean the pump. It’s already over an inch long and seems to be getting along fine with the others. I’m wondering if there are likely to be any others or if this was just a fluke?
I’d say there might be more lurking around, or he could just be the lone survivor.
May i get the email of the author?
Hi I’ve got to my pond and 1 has laid eggs on the side of the pond if I’m careful can I move them into a holding net designed for keeping them safe? However not so sure as to how to move them! Some are stuck on a plastic spawning brush! ?
I recommend moving them while they are attached. Just take them out and transfer to the desired nursery.
I woke up this morning had a cuppa by the pond and noticed little black and brown fish coming up for sunlight , I’m chuffed my fish have had baby’s I’ve only found seven so far and have separated them from parants. But if it’s like you say they can lay a thousand eggs will o get a thousand fish ? Apart from the ones the mother and father will eat ? Really informative thanks
Many of the eggs won’t survive, so probably not 🙂
Hi,
I am noticing something very weird and finding no solution online. My goldfish fry are dead and stuck to the fin and tail of one of my mail goldfish. Is there any way I can handle this situation? Or do I allow the other goldfish to eat it whenever possible. I do not want to damage the fin while pulling the fry out as I know they can be very sticky when they are dead
Any help would be appreciated.
I would try pulling it off gently with a pair of tweezers.
I have a small pond in my backyard. Last summer we put 7 tiny goldfish in it that we bought from Walmart. We thought they had died over our short winter of only a few days of below freezing. So in the spring our grandson\\\’s wanted some more so we went and bought 2 more one had black on it. Then the next thing we knew we had 9. And now we have about 50 babies of 3 different sizes. And we haven\\\’t cleaned it out the leaf litter since spring a year ago.
Wow just goes to show how they proliferate!
So the female can lay eggs without a male correct? Will any of the eggs become fish or what will they be?
You are correct but they will not hatch
My gold fish lay the eggs in my aquarium tank i absorved and put my female fish in separate tub and do hand breed with 3 males and one female.after a day the eggs are changed colour from green to light pale green. Why its happen?
Is the eggs fertilized or not.can u undestand my problem please give the answer i am very excited about your answer please sir thank you
The only way to tell if they are fertilized is to check for eye specs in the eggs. Are they looking fuzzy? A white fungus could cause them to get lighter in color.
Hi after 4 days I\\\\\\\’ve managed to eventually put the spawning mops into a heated aquarium set at 22c originally they were in a bucket but the weather changed temperature dropped just wondering if the eggs will still be ok just a bit concerned as it\\\\\\\’s my first time at trying to breed goldfish the eggs came from the pond beginning of June.
They should be ok just might take longer to hatch
Amazed to come across this article. Living in the UK and have a 1000 litre garden pond which has 3 goldfish and 7 shubunkins for the past 8 years and never had any newborn fish in there.
Weather has been warm over the past few weeks and last Monday was amazed to see a new small fish only around an inch in length swimming about with no bother from the others, it appears to have the same colouring as one of the largest shubunkins which I suspected may be female as it was always being chased and nudged by the others.
What are the chances of it surviving as in the UK here the weather temp will drop by around 5 degrees in the next month or so
5 degrees shouldn’t be too bad for a juvenile goldie 🙂
Good information, I learned more information about your article. Thankyou
Thank you, Harshitha! Glad you enjoyed it!
Just read this article as just went to clean my pond pump and feed fish and found at least 20 babies all about an inch long trying to devour the food!! Pond is old but teaming with life over the years including frogs, newts galore and once before baby fish. 10 years ago I bought 5 goldies/shabumkins, peaked at about 10 five year ago then dwindled to 4 over years until today!!! Far too many fish for the size of pond, I will be interested to see how many survive….. After all WINTER IS COMING!!! ?
Wow congrats on the spawn, Ian! Most might get eaten, leaving you with a more manageable amount 🙂
Not sure if my fish are male or female yet but I’ve had some die. It’s a small tank and I not sure if I should keep changing the water everyday or not.
How old does a Fish have to be to have a baby
Usually a year, but sometimes earlier.
We have a very plump goldfish being chased and bumped by the other one and the ly keep going in the plant we have and acting as if trying to spawn. How long do they do this before they actually lay and fertilise their eggs?
well our gold fish born lost of eggs but i wonder if the gold fish ate the small fish and eggs
They definitely can eat them 🙁
Hi. We run a small community garden here in East London and we made a small pond out of a plasterers bath! We had two goldfish and one day I saw a few tiny black fry! Imagine my surprise today as I cleaned it out for the first time in a year and a half to find 13 small baby goldfish – all approximately 3.5 cms long. They’ve survived with the parents so far – and so my question is are they still safe with the parents? I feed regularly but since I’ve put them all back in together one of the parents is being territorial and chasing them around the bath. By the way your information is very clear and informative! Many thanks. Sally.
If you see chasing, the babies could be endangered. I would probably separate them if I were you 🙂 Glad you liked the post!
My pond fish have just spawned and asked a5 aquatics for advice as it’s out of season. They suggested squeezing female or fungal treatment. I ignored and put in 3x chimney like filters and have hundreds of eggs and now set up tank in house maybe they all die but least I have tried. Good job I didn’t listen to “experts” found all info on line as I didn’t realise this was actually spawning .
Wow, that’s quite a story, Tracey! I hope your eggs hatch!
Glad to have found your site. I’m a newbie so i thought the others are just trying to eliminate the weakest among them because they keep on chasing after them. So i separated them because they were already injured (some scales fell off). The next day, i saw white eggs on the quarantine tank. That’s when i realized they are actually spawning not fighting. But the eggs were not fertilized. Now i know better next time.
Wow, that’s a surprise! Thanks for sharing, Jen.
I have three goldfish
What do I do
Are they breeding?
Thanks for your article it helps so much.
You are very welcome, Tasnuva! 🙂
my shubunkins bred all day long .. I took the duckweed out of the pond when they finished. and put it in a separate pond … now I have over 500 fry /. that’s my first attempt too not bad ay..
Congrats on the spawning and fry! 😀
Hi everyone I hear pretty good things about koil fish I’m very excited it, my female fish had clear eggs last night but I don’t know if the eggs had been fertilizer by the male what I did I took the ones that got stuck on the rocks or plants I have, I took one of the male out of the tank and push the belly gently and took the sperm out to fertilize the eggs just incase I hope I did it right and I apply a little bit of methylene blue for the funges. Now this is my question and big concern 1st question is. Is it ok what I did and my 2 question is. can eggs be fertilize after a day of being laid
I believe eggs will reveal themselves to be fertilized within 3 days. Hand spawning can be done right but is only recommended for advanced keepers.
We have a 29 gallon tank. We have two goldfish. The two have been together for at least 3 years. The one fish is 8 years old! One of my kids won him at a fair. 2 weeks ago, my husband was cleaning the tank when he asked when did we get s third fish! We were shocked! How this little guy survived is beyond us! He is getting big quickly! We’ve decided to call him Bruno. Gotta have a tough name to survive his odds! We thought we had same sex fish all these years! Did I mention, they are two different kinds of goldfish? We are utterly amazed at this!
Yes, very different kinds of goldfish can certainly breed. 🙂 Would be super interested to see what Bruno looks like! 😀
Is it possible for goldfish to be egg-bearing during this time of year? I have 3 and Darwin is looking bigger and hiding more. I also can’t tell their genders so can you help?
If they are outdoors, fish can breed anywhere from Spring to Fall. Spring is the most common time.
My fish is quite big in his or should i say her tank she was upset losing her mate and the ti y fair fish got bit bigger and now 1st time my fish has a gia t belly and i have no idea how to look afta babies hope theres not too many or they will be squished ?
A male will need to be present at the time of “giving birth” for her to give birth to fertilized eggs, otherwise they will all be infertile.
My goldfish laid eggs third time today within 1.5month of period in a small glass bowl. Is there any possibility this time to hatch. As two times it fails to come out baby fish. Please suggest what should I do for hatching these eggs.. Answer fast… Please
Check for eye spots after a few days on the eggs.
There are eye spots on the eggs. I have separated those eggs from fish and kept bowl filled with water as it is. Is that right or I need to take some special care?
A tank would be better than a bowl 🙂
Excuse me I would really love a pet fish do you know a good place where I can find a fish to buy and how do you tell a fishes gender apart how do you tell apart girl from boy and one last thing to ask I was wondering when I get a pet fish which species makes the most eggs
I meant to give you a four in a half rating sorry
I think they can all lay lots of eggs, Danielle 🙂 I’d recommend checking out our article on places to buy goldfish for the answer to your other question.
Wonderful article
I actually dont lnow which fish of mine is male or female. Please guide me how to examine it?
Check for breeding stars on the males gills! 🙂
I have two gold fish and one looks pregnant. I saw this about 4 days ago. The other fish is chasing her around all the time. How do I know the other one is a male? He doesn’t have white speckles on his gills. How long will she be carrying the eggs for?
Only time will tell! 🙂
By the way, they are in a cold water tank, but it’s summer here. Will they breed?
Usually warm water is needed for breeding.
I have a question. How do I know their genders a male or a female?
Check for breeding stars on males during spring.
Please help my goldfish eggs are yellow,white and transparent i think the transparent ones are the fertilized eggs but there are only about 5% transparent eggs in all of the eggs…i couldn’t remove all of the white eggs because there are tons of them…and i can’t remove the transparent eggs from the white eggs because im afraid that i might harm them or break them…please give me advice
Some find cherry shrimp get rid of the unfertilized ones.
It’s very useful but I would like to know what temperature do the eggs need to hatch.can I use a aquarium heater ?
A heater can help speed the hatching process. Keep temperatures in the mid-high 70 degrees F
I’ve had heaps of baby goldfish hatch in my pond ranging all sizes, I’m not sure what I’m doing right but it’s working 🙂
Well congratulations Beverley! When you find out the secret please do share 😉
Very good information, have learned heaps, Have had goldfish for years in an outside pond. Earlier this year was given 4 small goldfish. Some months later I noticed many eggs, but all looked infertile attached to plants, I put some in a separate lily pond, to my amazement counted 10 babies. I transferred the babies into the big pond. Think that was a BIG mistake.! Could the big Goldie’s eat the babies. If so I have murdered them. I live in Western Australia and we have summer now, will the lay again. If they do, is it best to keep babies in a tank, how long would they have to be separated, before I can put them in the pond.
Cheers Bev
Yes, big goldfish will eat babies 🙁
Second time today my fish has laid eggs but she keeps eating them n it’s only her that’s eating them
Yes, you will probably have to separate them for the eggs to survive.
I read your comment about egg binding but didn’t see any details about it. I have an outdoor pond with koi and goldfish. One of my goldfish looks egg bound (very pregnant) and has been that way for going on two months now. Her activity seems normal like the other fish and her scales are not sticking out. It is January in Oregon and the water is cold, outside temps have dropped to the 20s. Will she be able to lay her eggs in water temps below 50 degrees? If not, what happens if she remains egg bound until the weather gets warmer in the spring?
If the fish is egg bound, that can be a very dangerous condition. However abdominal infections can cause swelling without pineconed scales.
I wondered about that. Do you have any suggestions on a course of action? The local pond suppliers I have checked with do not know anything about goldfish breeding or medical treatment and my vet does not treat fish. Thanks!
I would isolate the fish and see if you can find any other symptoms of illness.
I have a question, l had so many different kid of fi in my tank , only to survived : angel fish & coiy fig . I was away my granddaughter sent my a picture of eggs all over the rocks my 2 different kind of fish mate & how long it takes to hatch ? Thank you
It probably depends on the kind of eggs.
Cute article Pure Goldfish and very helpful. I wondered where the smaller, dark coloured fish in my pond were coming from. Never occurred to me my larger goldfish were breeding! I’ll enjoy watching them grow – which they seem to be doing very fast. I only noticed them a couple of weeks ago and they’ve already doubled in size and now getting bold enough to hang around the ‘feeding frenzy’ when the adults are eating.
Thanks for your article – your love of goldfish is very apparent!
Thank you for your kind words, Adrian, and congrats on the newcomers – or should I say “new swimmers” 😀
Well, great. This is helpful, but now i’m a bit stressed because I don’t need any more fish in my tank.. hopefully my fish don’t lay eggs, but i have seen my pet fish Ponyo stick around my other pet fish Pebbles. :/
They will eat the eggs if you let them, no babies then 🙂
I have a big black gold fish and a normal silver gold fish the black one had been chasing the silver one all the time and now there is while stringy blobs floating in the water I’ve never noticed them before they fish haven’t ate them either but tonight I scoops the white blobs out and but them alone in another tank (obviously don’t want the mom and dad to eat em!) U reckon they r eggs?
It very well could be! Are there little round things in the blobs?
Our goldfish hatched eggs in the aquarium and its dirty. I cant clean the tank because the eggs is all over. I successfully removed the parents tho.
What should I do? Should I let the tank the way as it is?
Ps: I cant remove the water oxygen too. Coz some of the eggs is attached to it.
Pps: I loved your infos.. its more informative ?
Keep the water clean, use a small siphon with a sponge on the intake 🙂 Glad you like the site!
I got a goldfish 2 months ago and now she apparently laid eggs without a male I have a really small aquarium and some colourful rocks at the bottom I don’t know how they will hatch could you help me please with more information
They won’t hatch without a male :/
Hey puregoldfish! I bred some shukins(egg phoenix) when they are around 4 years of age! A year later I have a hundred of them and plan to sell them 🙂
Now about the age, do goldfish breed/mate for life, no matter if they are ten and fifteen years old??
I believe they don’t mate when they get old, but as to how many years they will continue to spawn, I must admit I am not sure 🙂
i love gold fish
Sir, I bought 1 female and 2male goldfish yesterday and today morning i found eggs on the floating plants root and I moved it suddenly to another tank outdoor. But it only have very few eggs will it survive. And did i need to add anything else to the tank
Your goldfish may spawn again if you keep them together. Keep the water really clean 🙂
I managed to hatch 22 baby goldfish a few years ago. I kept them in a small aquarium until I thought they would survive the pond… That was a big mistake as the babies were all eaten by the adult fish. I currently have some eggs that I am hoping to hatch. I will leave them in the aquarium a lot longer if I am successful
I hope they make it Cherie! Baby fish are so much fun.
Hello, I have a pond in the back yard with koi, turtles and goldfish to say the least. One of the goldfish is HUGH with eggs, bigger than she was last year. She’s having trouble swimming and staying upright due to her belly. There’s a male that’s attempting to get her to lay her eggs but it hasn’t happened yet. I’m starting to wonder if she is egg bound or I’m mistaken and it’s bloat. What are some steps I can take to check if it’s one or the other. I’m so concerned about her well being.
The only reliable way to tell for sure is to try to take a sample from the vent of the fish with a syringe. A vet should probably do that procedure.
Thanks …..a very helpful information regarding goldfishes…..
Glad you liked it 🙂
hi my goldfish just layed eggs so i took them out of the tank but the tank that the eggs are in is very dirty what should i do ?
Change the water to keep it clean 🙂
hi my fish were breeding and i went downstairs to get water but when i came back upstairs my fish were dead!!!:( do you know what happened? please respond soon.
That sounds like there may have been too much aggression going on.
Hi! I just hand-stripped my female and my male goldfish. All of the eggs were white. Does this mean that the female is too young to breed? Or the eggs were infertile? Finally, when I looked at the eggs, they looked like they have been squashed. Help me in this stuff. Thanks in advance. 🙂
White eggs may be infertile if no eyespots are seen. The yellow ones are usually good.
We have a fantail goldfish that looks extremely swollen. If she is egg-bound is their a way to help her expel the eggs?
You will need to rule out internal infection before attempting to do that. Feel the abdomen and see if it is mushy, look for redness at the vent.
Hi this June 2018 Racoon ate all my goldfish that were in my pond.He found a way to drain my pond by disconnecting my filter retern. I was going to get more fish for the pond but I was waiting on July 2, I happen to notice baby’ fish all over the pond. My goldfish had layer there eggs before the Racoon ate them. I now have about 100 fry babys in my pond I’ve had my pond 18 years never had frys now there different sizes fry I feel like a no father.
At least they left a legacy!
My gold fish are spawning in my tank! im worried because they were aggressive with my other female. so aggressive that they ended up killing her. i don’t have any other tanks to separate her into at all right now, she’s laid a egg batch but my plecos ate those, but i separated another batch into a small clear ball, and i put some light netting over it so that they don’t get to them. should i leave them for my plecos to eat? or leave them with the netting and pray for the best?
You will probably need to separate them for them to be able to survive.
I’ve had a small pond with goldfish for six years now. We’ve had the same five fish for the last 3yrs, wintering them inside & pond life for the summer. Never had any babies, or any predator problems. Two summers ago, I made the pond half again as big and it’s roughly 6ftx9ft now. The fish had grown quit large. As big as my hand from feeder fish from the grocery store.
This year, we attracted the attention of a great blue heron! Our dogs finally made it feel unwelcome enough that we havecnt seen it lately, but not before we were down to one fish remaining!
Imagine my suprise, while I was wading in the pond last month to clean the pump……dozens of tiny fish swimming around my legs!!
I’m feeding them flake food & hoping for the best. If I miss any in the Fall round up, will they freeze over until spring?
How big are they? Really tiny fish probably won’t make it.
hi i’m anton, thank for this short but very amazing facts i’ve learned about goldfish.. i hope there’s other who read this and learn too… i often cleaned my fish tank depending on the color and how slippery my tank… before i clean i always look carefully if they spawned egg because all female goldfish are almost about to spawn…
how to know if my goldfish are ready to spawn?
Check for chasing behavior firstly
Firstly, i am currently 13 and i care about my gold fishes in my pond in the front yard, and i am wondering could there be the possibility of all of them being females?? i researched a bit and found out something called “dropsy” and all my gold fishes bellies are indeed kind of big which worries me, however they don’t show any symptom of dropsy. And apparently in spring and summer it’s breeding season? We also added 2 extra fish today which both is most likely to be males, should i separate some of them into pairs?? Thanks.
(sorry about my wording)
Do they look swollen, or just plump?
From which day do I give food to golden fish fry
Usually day 4 I believe.
One of our goldfish die about 4 weeks ago from jumping out of tank and after reading a bit now we suspect it must have been a male, as it used to chase the other one (we taught it was just more aggressive-it killed another fish from “tail envy” before. Also it was growing rapidly and changing colour lately so we taught it was normal puberty behaviour. After “Banana” has been in the tank alone for 4 weeks we noticed for first time some eggs at the bottom of tank. Do you think “he” was eating her eggs all this time? Is there any chance these eggs could be fertilized from sperm left in tank? We don’t actually know how long the eggs have been there, we just noticed them today. Thanks!
Check for eye spots on the eggs, they could be! 🙂
Thanks for the info. <3
You’re welcome 🙂
Hi! I would like to ask about my lay eggs, some of the eggs are already hatch n some of them are not… what’s wrong with them is it normal?
and its already 3 days still not hatch… should i separate the fry?
I would, in case they are infertile.
Hey i my mom bought me a 50 galon tank and 2 pregnant gold fish. We clean the tank and fill it with live plants and leave the fish for like 2 hours. I feed them with some pelets and leave them eating. They did eat the whole pelet i gave them but something strange happen. I was watching youtube and gone check on them. I saw a really kind of disgusting red thick string in floating in my thank i call my mom and she go check my tank. She said its their egg…but i wasnt sure. So i go deep to the internet but i found nothing..about the strange red string i discover. What do you think is it? Im so scared that my fish will die ;-;
It’s poop.
Hi,i have 2 goldfiah and they laid eggs this thursday.they havent hatched yet.is thwrw anything to do?a kid next door disturbed thw water.though it has got something to do with it.
If they don’t hatch in 5 days they’re probably toast 🙁
Should I remove my goldfish from the bigger tank that consists of other fishes too n keep the male fish with her too?
If you have eggs, all fish need to be removed from the premises.
I have two fancy goldfish with fantails, not sure of the breed, but theyre very small, 1.5\” long each at most. Ive had them for a little over a year but I have had other fish before that lived to be eight years old without anything happening. I noticed these fish (Mulan and Mushu) were eating from a corner specifically and not really leaving that one corner for a few days so i thought something was wrong with the water and I went to go change it. This is when I noticed sticky bubbles in my 20 gallon fish tank all over the pebbles and their bamboo plant. . I\’m not ready to be a fish grandma but I feel awful about removing the eggs. What should I do if any of the eggs hatch? Are there places that take fry? Should I remove them all now or let them eat their own eggs? Help!
You can let them eat their own eggs if you have no interest in raising fry.
Yesterday I was cleaning out my fish tank and I noticed some eggs but I didn’t know they where eggs so I left the fish tank to dry for about 10 seconds will they live? Also I only have white eggs but they don’t have black specks my fish are coi Karp is it the same for goldfish and karp do karp also have black specks or are mine dead?
Koi should also have the black specks in the eggs I believe.
I have a new pond in my garden, and I transferred my goldfish from a couple of smaller ‘water features’ into it. I noticed some sticky egg like material, a while back, and hoped that we may have babies! I haven’t done anything special at all. Last evening, whilst enjoying my gin and tonic, and listening to the waterfall, I noticed that I had a LOT more fish then a few days ago. Voila! Baby goldfish! About an inch long, very active and healthy, and holding their own with the big guys! Again, I am in awe of Mother Nature.
Nature does the breeding thing very well indeed!
So, we brought a few big goldfish a few days ago and they’ve already laid eggs!! We went out to buy a hatchery to separate the eggs but how do I remove the eggs? Are they too delicate to touch? They are all over the gravel and side of the tank so I was going to get them with a net but wanted your opinion first 🙂
You probably can’t get them off the floor without hurting them. Your best bet is to throw in a breeding mop or handfuls of hornwort and hope they spawn again, then relocate it to another tank.
Hi
This is a long time after this event, but my shubunkins have just had their second spawn in a couple of weeks and I got my aquarium vacuum and sifted through the gravel to suck up any eggs that didn’t attach to plants or mops. Managed to collected nearly 450 eggs as I did count each one. It did take a long time! A few hatched the next day, and I think some are still hatching as where I could see several eggs together, they are slowly getting less in number. The water is cold about 16C. Time will tell how many I get.
That’s amazing!
I have a small preformed pond with 2 Goldfish, 1 Shubunkin & 2 Tench in it. The water has turned a reddish brown which I gather will be from leaf matter releasing tannins in to the water. The other day I noticed the fish chasing each other & it looked like they were spawning. I am wondering if it is save to clean the pond or should I wait a bit?
If you clean it, you might harm the eggs, I’d wait.
So may the 20th was my bday and i got a new shubunkin now 2days later ive noticed shes spawned and now the eggs are incubating and i was so happy as its the first time ive had fish thank you fot all the information on here and ill keep o u posted on how they get on
Awesome!!
The goldfish spawned this morning just as advertised. Water was foamy and left bubbles everywhere. The ponds lily pads now have little clear orbs even laying on top of the pads. I currently have about twenty goldfish in the pond and on average about five or six of the fry make it . I did notice that this afternoon the adults were not very interested in eating. Probably too much caviar.
Nature takes its course.
how can i sperated them it so hard they are really sticky and i don\’t know how what am going to do? And the water is warm which is good, and how do i grab the eggs from the tank?
Spawning mops are the way to remove the eggs but the fish have to spawn on them.
I have about 40 assorted adults and about 45 survivors from last year’s sawning. My two ‘supermum’ goldies and the shubunkin males spent all yesterday throwing eggs about.
I put 2 little ones indoors over winter and they are about 4 times the size of their siblings in the pond. Guess that is the warmth keeping them awake.
Lots of 2 inch 2 year old goldies need new homes!
My goldfish has these black little lines surrounding his/her pupil and I cant figure out what it is, can you help?
Sounds normal to me.
A few days ago I was given goldfish for my outdoor pond. The next day I found eggs on my floating plants, and now I can see black eye spots. I moved them into a separate bin with all of the tank features. I do not have heating though. Do I need this? Also are there special additives to increase likelihood of hatching?
One more thing- it is mid 80s right now where I live. Should I move them inside
No you don’t. They will just hatch slower. Clean water.
Do we need to add anything in the eggs bowl as a feed? and How to remove the infertile eggs from the bowl?
Don’t feed until 3 days after fries have hatched. Shrimp will eat infertile eggs.
Thank you for your reply. One more question, do i need to change the water from Eggs Bowl?
Yes that’s a good idea.
thank you very much for your answers. Now the eggs got changed to fry, can you please tell me how to take care? what to feed? and how big my bowl should be as there are more than 70 fry’s are there..?
.
More water is beneficial for fry development. Time to switch to pellets like Hikari first bites.
First day there were so active, after that there were so quite, is it ok? and how often i need change the water.?
Go by the water tests.
i have had a female goldfish for about ten months, and she’s alone in a tank. i woke up this morning to a bunch of eggs everywhere all over the plants and don’t know what to do! do i just leave them there or do i have to take them off the plants? PLEASE HELP
Either one. They aren’t fertile so they’ll rot unless she eats them.
Very nice sentens about gold fish
Thank you!
We have one fully grown shebunken in our pond (sadly, the raccoons got the rest) and she is full of eggs we think–been about 3-4 weeks now–when will she spawn them or is something wrong with her–she is huge?
She might be impacted if she is really swollen.
I thought I had 2 Male goldfish one died about 4/5 weeks ago now , I woke up yesterday to find 6 baby fish , ?
The legacy continues!
My female goldfish & male goldfish lay eggs 3 days ago. We’ve moved the adults into another tank. & they’re no tiny black specks on either of the eggs. And I’m just wondering if you could tell me why this is. We’ve had the pump on but on a gentle setting so that the tank is clean.
Thanks, Joanna.
Could be not fertilized.
We have had two goldfish I’m our small pond for the past few years. A month ago we went out to find probably 100 babies.
Exciting!
We have Shubunkins hatching. We didn’t even know we were expecting. Crazy how tiny they are. Guess what everyone will be getting as Holiday gifts this year. ?
Awww!
Well this is fine in tanks. Mine are in a pond. Over half is filled with oxygenating weeds which I thought would protect them when breeding. I should have 14. They leapt from 6 to this number. I feed them with flakes regularly, but I never count more than ten almost ever & I don’t know if they are the same ones each time.
I am hoping for more breeding, and that fry might be under the weed, until they feel they can break cover.
It’s best to take the weeds out if they have eggs on them, if you want a higher survival rate. To answer your other question, you’re rating the article 🙂
Do frogs eat fry and eggs?
Will goldfish ear tadpoles. I get lots every year. They grow legs and then seem to disappear.
Frogs can prey on goldfish, yes.
Goldfish can also prey on little tadpoles.
Thank you, I thought my sons fish were mating, so on your advice went and got a mating net and as soon as I put it in we hav eggs.Ive still got Bothe the male and female in there waiting for him to milt. Waiting to take them out watching to see if they eat the eggs but both seem pretty busy still.
Those spawning mediums can really do the trick!
Just discovered little fish in our pond. Managed to save/separate 15 in a floating net tank to keep safe. How long should I keep them separate? We only set pond up in May. It’s the bottom of a new oil tank. 5 fish & 4 plants were added. 2 fish 1 plant died. Everything else growing/flowering! We live in UK. We must be doing something right to have happy fish!
Separate them until they are too big to fit in the other fish’s mouth 🙂
Thank you for this article. I’ve read most of your writings and find them quite helpful. I have a 9″ four years old Fantail Goldfish that I rescued from a tiny, dirty, half full tank in a college library. At first, I thought the new younger Fantail that I purchased was bullying her, but the behavior has changed from nipping fins to violently going after her vent and running her al over trying to push her into corners. Luckily, the new goldfish is half her size, so I doubt death will occur. Her vent opening is quite red now from the constant mouthing from the smaller fish. In reality, I don’t see any tubercles on the new fish. The new fish has a round vent too. So, is this bullying or spewing behavior. I’m getting worried. I’m going to place the new fishing to a breeding box to calm things a bit. I’m pretty stumped as to what I should do. I don’t want Michio (9″ fish) to get sick or die from this situation. Any advised you can offer is greatly appreciated.
Sorry. Spell check changed that to “spewing” when I meant “spawning”. Lol
Both fish have red vents or just the female?
I have 4 goldfish and 2 of them are female. They laid eggs 5 times in this 6weeks is it normal ?????? Any help please……..( Now I have hundreds of fry)
Normal!
Mystery solved. Michio is a female who just dropped her eggs. My goodness. What do people do when they don’t want to raise fry? I’m figuring I need to find a goldfish savvy new home for the male or will a tank separator work? How often to do they want to spawn in an aquarium versus in a more natural environment like a pond? thank you
A tank divider will do perfectly. They can spawn several times over the course of a season. Let them eat the eggs if you don’t want to raise them 🙂
Thank you for responding. Everything has settled down now. They ate most of the eggs. I put three plant leaves with about 5 eggs into a breeder net. I’m waiting to see of they’ll hatch. If they do, then I’ll raise them properly. I’m reading everything I can find in order to take good care of them. I used to breed and raise Half-Black Yellow Leopard Guppies. So I still have some smaller tanks I can use. Thank you!
I have a 200 gallon pond in Florida (warm year round) with 5 goldfish, 3 about a year old, 2, 6 months. Range in size from 6 to 12 inches. Just had 10 babies already about 2 inches long. How many fish can I have in there and what should I do if they have more babies and over populate?
No set answer for how many fish. Too many factors. But you could always put the extras for sale on Craigslist or eBay 🙂
Hi , Thanks a lot for the info, it was a great help, it’s been 4 days now, the babies hatched 2 days ago and they are clinging to the sides of the bucket from this morning, it was quite amazing cause this is the first time I got to actually see goldfish eggs and babies, I truly hope they survive, will keep you posted, Thank you so much appreciate it !
Woohoo!
Only some of the eggs has the black dot
Remove the ones that are infertile
My goldfish is really fat and is not showing any signs of sickness so I think she has eggs. She is in the tank with a male but the male isn’t chasing or bumping into her. The problem is that I am keeping the goldfish with some large pond minnows I caught in a trap. The goldfish seem to be afraid of them but I have no were else to put the fish. I want them to have babies so what should I do?
Check out our breeding guide 🙂
Hi, We already had one small Comet goldfish, and a friend gave us two big goldfish look like Oranda and Telescope( according to our google search..) just three days ago. So we put them together in a big tank and hoping to see them getting along together. But after seeing lots of chasing up each other straight away and at the end Comet and Telescope chasing the Oranda extremely, we decided to separate Comet and Telescope from Oranda. So Oranda stayed in a big tank alone. This was the first night. Then what I found next morning around 10am was a hundreds of eggs have been laid by Oranda….Since we didn’t know anything about how to deal with eggs, we quickly searched and realised about the reason for chasing up etc and also the eggs need to be fertilised so we put the Telescope back in to the same tank with Oranda. waited a bit but the Telescope just started eating the eggs so after sometime we removed both Oranda and Telescope to the other tank and now the tank is empty but the eggs. It’s been two days but they all look white, not yellow or orange. I doubt the they have been fertilised but I will wait for few more days and if nothing changed then I will clear the tank and put all of them back together. I’ve read that this will happen every week or other week and some say remove the eggs to the other tank and some say remove the parents, and take the dead eggs out etc but my question is what will be the best to keep those egg in the best environment..? I would rather keep all the eggs in a small tank to watch than leave them in a big tank and keep the fishes in a small tank, but moving all the eggs to the other tank sounds like a huge job. So can I just move the Oranda when looks like ready to lay eggs to a small tank? but with or without the Telescope?? Just so many informations that we are a bit lost!
Use a spawning mop or clump of plants to catch the eggs. That’s what I do it is much easier.
Thank you, I was finding out about the mop and now I’m going to get it! So when it laid eggs next time on the mop, I will just move the mop to the different tank and keep the fishes in the original tank, won’t I?
Yep 🙂
Many thanks! It really helped.
🙂
Hi Meredith, following the conversation before, I got the mops and successfully caught lots of eggs second time and moved it to the different tank and now all hatched!! Looks like there are over 150 or 200! So happy and it’s been almost two days and I was wondering what to do with the mop as still have eggs(probably the empty sacks)and eggs that didn’t fertilised( very clear colour ones). The babies are clinging to the mop but should I take it out and clean and put it back??
And next challenge is the food… Any recommendation with baby fish food? Sorry about many questions. It’s still all new to us!
Many thanks

Hi i have just hand bred my pops goldfish i have made a nursery pond but atm they are in a large glass bowl with regular water changes should I put them in the nursery pond for better hatch success or should we keep them in the lage bowl
I would not move to the pond until they are older.
My fish have had so many babies naturally and I’ve been trying to catch the fry every morning and evening when I feed them. I have 4 adults, 2 female and 2 male. I decided that this was verh difficult and I don’t want to miss any so when I noticed the spawning behaviour again, I decided hand breeding is the only way to completely protect the eggs as I can seperate them in my floating fry net I made for the pond. However, during mu hand breeding process, I am only getting milt out of one male and no eggs from either female. May I add that both males ate taking turns in chasing both females. What am I doing wrong as I am struggling to hand breed and would really like to do this for a better success rate. Like I say, I have found almost 80 fry between 4.5mm and 2cm so they obviously old enough to breed but why can’t I do it. Any suggestions?
I have found personally that handbreeding does not have as good of success rate as natural fertilization.
Hi, just found this cool article on how the temperature of the water the goldfish eggs are in effects the gender of the babies. I knew this about crocodiles, but not goldfish! Just thought you guys might find it interesting. Especially if you know what you want the babies gender to be.
https://www.sciencedirect.com/science/article/abs/pii/S0044848605006137
Thanks for sharing! I talked about that on this post but cited a different article than this one. So interesting!
Within I day I had my male and female goldfish lay eggs with about 20 hatched and a week old in their own tank.
Now a week later I have returned home to find they have eggs again. The eggs are in a breeding net in the parents tank until they hatch. My question is when they do hatch is it safe to put the new babies in with the 1.5 week old fry?
Am I better putting the eggs into the fry tank now before they hatch?
Mixing batches can result in the bigger ones eating the little ones at some point.
Thanks so much
Will the vacuum filter suck up all the eggs laid and will the aeration bubbles kill the fry?
Aeration filters fine, a vacuum may remove the eggs. That is why bare bottom or no vacuuming is good for baby eggs.
Hey my girlfriends goldfish just laid eggs a few days ago and we still haven’t seen any change. We do have a male with her and we were able to separate them from the eggs cause some were disappearing, probably from them. The eggs have just been white and no color change has occurred to them. Are these just infertile eggs?
Sounds like it.
My pond is alive with spawning at the moment.
One female, 2nd year, has been chased, bumped, nudged and seems exhausted.
She has lost scales from one side from being pushed against the sides of the pond. Then she goes into a catatonic state, hardly moving or breathing for hours. Suddenly jumps up and starts swimming with the others, then the chasing starts again.
Can you comment on what is happening?
It is probably time to separate. She is getting over spawned.
Very useful article and comments often of value . Just one question that may help others -What diameter are the eggs? I have 5 large fish and eggs very small say max 2mm diameter . I think they are fish eggs because of the large numbers and from the behaviour of the fish. My first thought however was that they might be snail eggs but I thinking about it I remember snail eggs are in clusters in a single jelly globule.
The eggs can be quite tiny. Snail eggs are not usually laid individually, like you said, unless they are nerites
Hi Meredith
I collected my goldfish eggs on mops
And put them in a separate tank
The fry hatched and I had quite a lot
I was really pleased
I’m feeding the dry food like a liquid
Each day more are dying now I think
Only about 5 left so upset
They didn’t seem to be growing very quickly either
I have them in a tank it isn’t huge I have a a few oxygenating plants in there and
I top up the water with water from the pond wonder Why they have died ? Can you help ?
Could be several things but most likely starvation or flukes. Liquid fry foods don’t generally work well for goldies.
Thank you for that article! I got 3 gold fish 2 years ago and yesterday I saw 2 chasing each other. Sure enough, they ended up laying eggs and I separated the eggs from them. Today they laid MORE eggs and I had to separate them again! Both tanks got really cloudy and I heard that that was the fertilizer from the male. Hoping that the eggs hatch and I can have a new generation of goldfish!
