clown fish?

the metamorphosis you are referring to is also called settlement. That is when a fish larva (which is still a fish, not insect) "metamorphoses" into something that actually looks similar to a miniature adult of the species and loses its photoactivity; most fish larvae are photoactic which just means they are attracted to the light. I think you are confused because of the terminology. A fish larva is nothing like an insect larva really, it's just a broad term for "baby".
