A few thoughts: 1) there's no such thing as a false clown, 2) if you meant false percula, that's also a poor term. It's like calling a German Shepard a false lab - different species. I think you were attempting to refer to an A. Ocellaris. No, it's not an Ocellaris. It's in the clarkii complex - though I honestly don't know which one. Try googling or do some research on the Clarkii complex and find which one you think it might be. Furthermore, if that fish has been alone for any amount of time, your "he" is likely a "she" and you'll want to find a juvi or at least another of the same breed much smaller as its mate.
