I am interested in getting a smaller tank and putting in some plecos just fer fun. they are my favorite fish. any one got any advice on what i should get? like how big of tank for about 3 plecos and what plants they like and what stuff they like and the filter and all that junk? remember, i am clueless in this fish stuff, so please speak in simple terms and explain things. thanks.
