I am planning a 40 bdr tank with at least a 29 gallon sump, and I would like to keep more than one pair of true perc clowns in it. Is it even possible, and how many would I need to keep? I already have 2 pairs (separate tanks right now) that I would like to be able to put in my new tank, but I am not sure if it will work and if so if more would be needed to reduce aggression.
