have a percula clown in my 55g along with a yellow tang, bangai cardinal, firefish, and lawnmower blenny. today i added a maroon clown of same size as perc....the FIGHT HAS BEEN ON SINCE...perc has maroon clown fins pretty frayed up and maroon is just clinging to the surface in the very front of the tank. he is looking pretty pathetic. Does he even have a chance?...Will the perc eventually chill out or is this a fight to the death?
