I was gonna setup a heavily planted 55g tank and plecos have always been an interest to me. I was wondering 2-3 species of groups of 4 of plecs I could setup in here? I was looking into leapord frog plecos (I think L-134?) and clown plecos ( I'm not sure on the L number) and maybe one more? Could these work together? And is there another species that could work in there or something? Leapord frogs are the ones that I want so what are two more species can I mix in?
