I had 2 Ocellaris clownfish in my tank for over a months and they were doing great. One ate alot more than the other but looked ok. Then I put a Tourch and Fox coral in my tank. The one that ate alot took to the coral right away. The other on stopped eating. Well he died about a week later. So I bought another one. Now the the first clowfish attacks the new one. The new one stays up in the corner of the tank. I see him eating some but not much. Should I take the first one out of the tank for a few days??????? They are both about 1 1/2" long. Is it possible that they are both females????
