the baby fish goes to live in the coral reef until they are old enough to venture out on their own.
Since this is not my area of expertise, I searched Google under the key words "clown anemonefish babies" to get this source:
Here is its information:
Anemonefish babies: Anemonefishes form permanent pair bonds that sometimes last for years. The male usually selects the nest site, often a bare rock near the sea anemone which he clears of seaweeds and other rubbish. The female eventually helps out. After the female lays on the site, the male scrupulously guards and cares for the eggs, keeping them well aerated and clean. The female helps out sometimes. Larval fish that hatch from the eggs drift with plankton for 8-12 days before settling to the bottom and changing into a juvenile fish.
How does the baby fish find an anemone host? Some species apparently follow chemicals released by the anemone, others find one by sight, for yet others, it is apparently simply by chance. One study suggests the fishes use the smell of leaves from the rainforest to find their way to a suitable habitat. Even so, this is not the end of the problems for the young fish. If the anemone already has resident Anemonefishes, the new fish is usually bullied by the residents and even may be driven away.
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps a little more. Thanks for asking.
