Clownfish difference

[Lovesfish]

what is the difference between a true percula and a false percula. I know its dumb to ask but I don't know and I'm curious. thanks ahead of time.

From what i have observed, True Percual Clowns have more black outlining on there white stripe. They also have 9 Spines on there dorsal fin.

Correct me if i am wrong anyone.

The only real way to tell them apart is by the dorsal spines but i will be amazed if anyone has ever managed to do this!

Whilst its true that percs tend to have black borders around their markings; I have also seen False percs (Ocerlaris sp?) with similar markings as well as percs with little or no black.
