i just recently bought two small clown fish from my LFS. i all ready
have one fully grown false perc in my tank. does this meen that the
fully grown perc will become female and will be able to breed with one of my other clowns
You don't have to start a second thread about basically the same thing you know. :thinking: Your ocellaris clown is already female. Don't know about the rest of your question.
I do not think that any of your clowns will breed in your tank because they must feel safe. They probably don't feel the eggs will be safe with an extra clown in the tank. IMHO, bring the ocellaris back to your LFS.
