So I have had two small(2inch) firemouth cichlids, and a small(3inch) Oscar in a 29gallon tank for the last 2wks. One of the two firemouths is clearly dominant over the other. I just expanded from aforementioned 29gal to a 60gal. I filled the tank with de-chlorinated water about 4 days ago. Last night I transferred the fish to the big aquarium, and also took most of the gravel, and 10gal of water from the smaller tank too, in hopes that it would bring some of the existing good bacteria with it. This morning when I woke up I discovered that my submissive/nonaggressive firemouth has lost almost all of it's color. The other firemouth and oscar are still bright and lit up. Should I be concerned about the loss of color in the other firemouth, or is it common for a less dominant fish to subdue it's colors?
