When fish is ready to lay eggs, they show some signs and we should observe them closely so that we can take care of them even more. Likewise, clownfish also show some signs before laying eggs. All these signs are interlinked so watch them very carefully. When the eggs are being produced, the belly of clownfish becomes large.
This is because of the egg-producing organ enlarges. The size of your clownfish will be larger than the usual overall as well. So if you see your clownfish is growing bigger, you can expect it to be pregnant. But this single sign is not enough, you have to look for other signs too. These protrusions are nothing to worry about. Actually they are the sex organs that are necessary for the fertilization process.
So I have a pair of clownfish in my that live in a BTA. This morning my 10 year old called me over to tell me that the clownfish had eggs. I told him that I didn't think they had had eggs, but I went over to look at what he was talking about and I have no idea what they are.
They tiny little round dark things on the underside of a rock right next to their anemone. They seem to be attached to the rock with something clean and kind of wave around a little in the current.
Both of the clownfish seem to spend a lot of time next to these things and putting their mouths on them. Is it possible that they are clownfish eggs? I've attached the best pictures I could get. Here are the clownfish and their anemone.
The potential eggs are toward the right next to the male clownfish. Here's a couple close ups of what I'm talking about :. They're orange intitially like sushi roe , and they turn darker as the babies develop with a silver tip where the eyes are. Almost certainly what you see in the photos. Pet peeve: anemones host clowns; clowns do not host anemones! Yes they're are eggs, in a few days you should start seeing the silver eyes in the eggs Sent from my SM-JT using Tapatalk.
While we saw no difference in spawning frequency or fertilisation rates between the two groups of fish, the impact of the artificial light treatment on hatch rate was staggering. Read more: Why does Nemo the clownfish have three white stripes? The riddle solved at last. At the end of the experiment we removed the artificial light and monitored the fish for another 60 days to see how they would recover. As soon as the light at night was removed, eggs resumed hatching at normal rates.
Clownfish, like many reef fish, have evolved to hatch after dusk to avoid the threat of being eaten. Newly hatched baby clownfish, like most coral reef fish, are small about 5mm long and transparent.
Hatching in darkness likely means they are less visible to predators as they emerge from their eggs. Our findings show that the presence of artificial light, even at relatively low levels, can disrupt this crucial process, by masking the environmental cue — darkness — that triggers hatching. In the video below, you can see the different growth rates of juvenile clownfish were in one particular batch. Some of the baby clownfish are still dark with only one stripe.
Others have two stripes. And a few have gone almost completely orange in color and have grown into their third stripe. Again, this is related to how quickly they grow. I noticed that the slower-growing clownfish also tended to be the slowest to adjust to the food changes or were least adept at eating the new foods. With two pairs of clownfish breeding on overlapping schedules, I was able to get an overall feel for the general timing of the spawning attempts and how long it takes for the eggs to hatch.
Both pairs, in separate systems, turned out to be regular with their spawns. Over the years, the clownfish have gone through periods of extreme regularity and other periods where no breeding activity seems to occur at all. When spawning regularly, the clownfish spawned about every days. The clownfish eggs hatched between 8 and 10 days after being laid.
The larvae often hatched on back-to-back evenings, which will drive you nuts if you are trying to collect them from the breeding tank. It is much easier to take care of the fish and rescue the baby clownfish if you set up a dedicated breeding tank. The clownfish seem less anxious, and they generally leave the newly hatched larvae alone if you need to snag the larvae out of the breeding tank after hatching. A great way to keep learning about clownfish, have a chance of establishing a pair, and eventually get your own clownfish eggs and babies is to check out these great articles about a few of the most popular individual clownfish species:.
If you liked this article, you might also like the articles I wrote about my experiences with breeding the Banggai cardinalfish and breeding the neon goby. But if you see it around in a local fish store or from someone getting out of the hobby, snatch it up. It is an easy read, has great pictures, and is a blast. The best overall book about breeding saltwater fish is Matthew L. Disclaimer: This is another affiliate link through Amazon. I like the Amazon links because you can read reviews and even browse the book online If you decide it sounds interesting, get your copy from your fish store or bookstore of choice.
Know that if you buy anything via that link, Amazon will know you came from here, and the blog gets a small credit. The book covers everything you need to know to get your hands wet and try clownfish breeding. A third option is Frank H. The pages are filled with graphs and tables, so it reads more like a research paper than a mass-market book. This book is also harder to get than some other books. Also an affiliate link. If you have ever had clownfish eggs in your tank, please leave a comment and let us know.
Link to a picture if you have one! Hi, Thank you for the article, very interesting and educational. After having no luck with nemos over the years, finally last night my flurry and snowflake clowns laid eggs!
I hope I can as successful as you and would love to have bunch of nemos in one tank! Thank you again, have a safe day. Thank you, Nix, and congratulations!!!
That is fantastic news. How fun is that? Thanks for sharing. In the event that you do post it to youtube or anywhere, send a note and I can post it here. Hi, I was cleaning my tank last night and noticed something attached to the left corner of the tank. This is the same corner that the male clown fish never comes out of.
I thought it was odd that he was always in the corner. So I think it might be eggs, it sort of looks like your pics. I will see if I can get a photo. My black and white Ocellaris clownfish had been laying eggs regularly for about a year and then stopped 5 months ago. I managed to raise about 2 dozen babies twice and still have the algae and rotifers going in hope that they will start up again. Is this normal?
Seasonal maybe? I live in Hawaii so our change of seasons is minimal. Also, if they do start laying eggs again, how do I get more babies to survive? Thanks for any answers you may have. Congrats on the babies…and figuring life out and living in Hawaii!! Sounds awesome. It is normal for the spawning to start and stop or have some seasonality. Our black and white Ocellaris clownfish consistantly lay down a fairly large clump of eggs 2.
Unfortunately, they lay only on the back wall and the eggs always hatch in the night. The night of the hatch most of the other fish in the tank stay close with their spikes up as they defend their right to first mouthfuls.
The females tummy bulges with new eggs by the time a batch has hatched and she is significantly larger than her poor, hardworking male.
Thanks for sharing your experience here. Awww…the poor hardworking guy :. Have you thought about buying or building a larval trap? You might be able to catch a few. I have eggs!!!
