I have a 55g SW with about 80#'s of LR!!!! I have 3 blue damsels, a yellow tang and a newly purchased Bicolor angle. The Tang and angle are about the same size but the tang seems to be the aggressor. In doing my reading it is said that the Bicolor doesn't last long after initial acclimation! Is this true? And do anybody have any experience with the bicolor angle? It's a beautiful fish and I am getting attached to it more so than the others! Good or Bad? Can someone help me please?
