Hey guys the thread title pretty much sums up my question. I have 4 male convicts right now in my 55 gallon tank, 3 of them at around 2 1/2 inches and the 4th one about 4 inches. Hopefully I'm correct in assuming that the tank isn't already overcrowded and if so what tankmates could be a viable option for me? I would definitely like to have some sort of pleco but I'm open to all suggestions. Thanks.
