As Beverly says, it could be interesting. Perculas and Ocellaris clowns are my favorite fish. I try to never keep just one simply because they don't look happy alone. I had one Percula a little while ago because only one was available. When I found another one, I added it to the tank. Well they went absolutely nuts, They knocked corals over in their enthusiasm. Things settled down after an hour or two, and they are now inseperable.
