ocellaris vs percula

[meiyouwenti]

I am just replacing an Amphiprion ocellaris but I think that I got an Amphiprion percula in error...The two fish that I have don't exhibit much colour differences (the percula doesn't have really darker bands than the other) and they don't stay still long enough for me to count whether or not they have 10 or 11 rays in their dorsal fin...How can I determine which one is which now? If one is more agressive toward the other can I assume that that one is the percula (they both are young and about the same size)? (I also assume that the fighting doesn't really start until they are a little older--these are only a few months old):question:...Is there any quick way I can tell which is the ocellaris and which is the percula? I obviously want to remove one and replace it with the correct species...Thanks

Unless your planning on breeding, I wouldn't worry about it.
Percula and Ocellaris are so close together even they can't tell each other apart a lot of time.
The fighting will start weather they are the same species or not. Its part of the sexual maturing process in clown fish
