I had brought two juvenile clown fish (not paired) and one is clearly dominated over the other. The smaller one seem to accept her dominance by twitching. I then introduce a 5 inch nem about a month later and the smaller clownfish loves it but his behavior has changed. He attacks the dominated one and won't let her near the nem, but when he is not in the nem, he accept the dominance from the "female". This behavior has been ongoing for about two weeks. I'm starting to see battle scars from both of them, will they stop eventually or should I remove that nem?
