i got a 37 gallon, 30"x12"x pretty deep. i got a 3" firemouth, 2 2"giant danios and a 5" common pleco. can anyone recomend anything else? i was thinking another small cichlid and 3 more danios.
you almost have to add some more danios, as they are schooling fish. i think that with 3 more danios, your tank should be fine as it is, because that pleco will poop, and poop, and poop to no end.
