A.ocellaris and A.percula are two species that are hard to tell the difference. Your best bet would probably be to pick up Joyce Wilkerson's clownfish book and see if that helps w/ an ID better. I think it has something to do w/ the number of spines on the dorsal fin.
I also recommend that book. She is a God !! How big is the clown? Mating might be a prob.... Usually you'd want to pair them as young as possible... Nothing is impossible though, I had mine alone in a 29g for about a year and every LFS in town told me it was too late to satrt with a new pair... After fighting for a week or 2 they calmed down and had eggs a few months after that. The way it works is that they will pair up then one will mature as a female and the other will stay male. Female usually being the larger of the two...
You can tell the diff between the two by their color patterns. Amphiprion Percula tens to have more "ragedy" looking finds... A. Perculas also usually have wider black bands...
Oops, didnt really answer your question now that I look back on it... If I had to guess (Im no expert) I would say you have a True Percula (Amphiprion percula)...
Thanks everyone.This fish has been with me for almost 3 years,and I always wanted to get him a buddy but the tanks bioload was topped out.Just recently a Dominal damsel that was 6" 8Odied of unknown reasons,for a couple of weeks it had labored breathing,all other fish looked fine and healthy.Than one day when I got home from work it was dead. So I was thinking now would be a good time to maybe get the clown a buddy.I'm thinking of going to Tropicorium(about a 40 minute drive)they breed many types of clowns and get a juvenile fish.Do you think this plan sounds like it would work. :?
If the clown is 3 years old, it may have matured. If your going to try anyways get a small juvinile and hopefully things will work out. They will more than likely fight for a while but it should stop in a week or so, if not they will more than likely fight to the death.
