All,
How come nobody has brought up the fact that it simply is not possible to positively ID a fish from a fuzzy photograph? You can form an OPINION, but to say that it is 100% one thing or another is simply not possible. The idea that it is a tank-raised fish brings up a whole slew of developmental and genetic artifacts that cloud the answer.
Aside from good collection data on a wild fish, I find that there is only one reliable means to identify A. percula from A. ocellaris - The former's dorsal meristics are usually X-15, while the latter is usually XI-16, and the dorsal is a bit taller. The problem is that you usually need to have the fish in hand to see this - there if often a little stubby dorsal spine that is difficult to count, even from a clear photograph.

p.s. - If I had to hazard a guess, I would say the fish is either A. percula, or has some sort of developmental issue (or is a hybrid).
