I currently have a 55 gallon with an XP3 and Penguin 200. The fish are 12 Demasoni, 7 yellow labs, 4 Acei, 1 male German Red Peacock, 2 bristlenose plecos, and 4 syno Petricola. Is this too much? I have a lot of Holey Rock in there and the aggression is not that bad. Everyone is about 2" or larger. Should I get rid of some? I like them all but don't want to have issues later.
