Hello, I just got a 150 that I will be making into an all male peacock hap tank. Currently I have a 55 gallon with yellow labs and yellow tail acei. I am curious if I can move the dominant yellow tail acei who is reaching over 6 inches and is getting a little too big for a 55 into the all male tank. I have the same question for the yellow lab, not because he is too big, but I think he is a pretty fish and would love him in the tank. I know these are "peaceful" mbuna, will they cause an issue in a peacock hap tank? I do not have my mind set on any peacocks/haps yet.
