HI, I have noticed in my 40breeder where I have a maroon clown and yellow tang only. I have had the clown 9 months now and its been in the 40 for about 5 months. I got a yellow tang about a month ago. The fish is wild caught and arrived in very rough condition. Day 3 it got real bad popeye. The tang is still very finicky but I notice it loves going to where the clown is and just posts up there in an aggressive manner. It will push its tail and bone (weapon) closer but if it gets too close the clown will bite him.
Is this normal dominating behavior or am I gonna wake up to a murder one day.
Any ideas, is this something that will damper down?
