Youd be surprised! A friend of mine who has absolutely no idea, has put them 4 gappies, 2 angelfish, and a pleco in a ten gallon tank!
Gappies started breeding like mad (she was wondering why do they have swollen bellies every now and then?) and after a year the angelfish and the pleco have grown to monstrus proportions and she was still wondering why. I told her as soon as i spotted the black dots on the guppy belies.
After two hours of explaining i got this: Oh right, i thought i saw a small fishy in there the other day, and i thought it was my imagination. :facepalm.
