I have three male electric blue haps and some plecos in a 40 gallon breeder tank. People have told me and I have read in a lot of places that I need tank mates to spread out the aggression of the fish. I am planning on getting a 75 gallon tank at the petco dollar per gallon sale since the haps are getting too big for ther 40. I am not planning on breeding them, so I want to keep it an all male tank. Should I just get some different kinds of haps once I have the 75?
