I agree with gobytron. I had 15 in my 300gal and all was fine for about a month and then they turned into territory control freaks. I even took out the dominant one and another became the dominant. It got to the point that they were bothing my other fish and especially at feeding time. Go figure 3" chromis pushing around a tang, trigger and my foxface.... they do look nice and I've definitely heard of success but you couldnt pay me to put those in my tank again. Mine were the blue green chromis.... The bigger they get the more territorial they get imo.
