alright guys i need some help on my next new fish for my 180...im deciding between a couple of fish. one of my high choices is a thin bar dat because they're not too expensive, good tankmates, and they wont outgrow my tank. thought about an aro but theyre too expensive for my wallet. iv heard dorados will outgrow my 180 which sucks cuz theyre awsome fish. was thinking about wolffish too because of there mean tendencies. give me some advice thsnks
