So I have a 220gal with 11 reds varying from 4-6 inches. I have raised all the reds together since they were about 1-2 inches. I now have one of the smaller ones that has become extremely territorial and gotten very dark. This is clearly a sign of breeding but where's his mate? He wont let any of the other reds come near or he chases them off. If one refuses to leave an all out fight breaks out. Is there anything I should do or do I just sit back and be patient? Thanks!
