Some people think clownfish need an anemone, like the bubble tip anemone, to spawn. ![]() Clownfish breeding and raising the larvae from eggs laid on the glass inside my saltwater aquarium is one of the coolest things I’ve yet experienced with this hobby. The Ocellaris clownfish, Amphiprion ocellaris, is probably the most popular saltwater aquarium fish in the world. The best clownfish salinity (the amount of salt in the saltwater) is 35 parts per trillion (ppt) at 79 degrees Fahrenheit, which could also be measured as a 1.025 specific gravity, to match the natural salinity of their home reef ecosystems. Still, that’s a lot of clownfish babies, if you can raise them all! Smaller species, like the common clownfish or even a designer type like the Snowflake clownfish, may only lay a couple hundred. Larger clownfish types, like the maroon clownfish, may lay 1,000+ eggs at a time. The number of eggs a clownfish lays at any given time varies based on: Please note that if you buy anything from Amazon due to clicking this link, I will receive a small commission on your purchase.

How Many Eggs Will a Clownfish Lay?Ī clownfish will lay anywhere between 100 and 1,500 eggs in a single clutch or spawning event. The good news here, however, is that hermaphrodism makes it relatively easy to establish a clownfish breeding pair. ![]() So, that’s why I said they have the potential to become mature around 1.5-2 years old.īut, as you can see from the example above, they could be much older and still immature, depending on the group’s dynamics. Then one of the immature males gets ‘promoted’ to become the mature, breeding male. If she dies, the breeding male changes gender from male to female. One fish will become the mature, breeding male, and the other will change gender from male to female and become the breeding female. If they remain together as a group, all the fish in the group – except for two – will remain immature males. They start out their lives as immature males. How Old Do Clownfish Have to be to Breed and Lay Eggs?Ĭlownfish have the potential to reach sexual maturity around 1.5-2 years of age. I say, “have the potential,” because a few environmental factors will influence this.Īll clownfish are hermaphrodites, which means they have male and female organs.
