I finally caught my Domino and took it back. They had a sale on tank raised ocellaris clowns ($18.99) so I bought my other one a buddy. Well, I thought there might be some fighting at first. I put the new one in the tank and it went directly to the other clown and they started shaking and cleaning the floor with their tails. I mean it looks like their having sex or something. I thought bars were bad. I bought both from the same store, maybe their husband and wife, I don't know. Now my tank is like the Playboy mansion. :loveface
