hey guys im new here and I have an odd ball question, no sure if this is the place to post it but here we go.
what are these guys? I bought them off kijiji thinking they would be good target fish(which they are might I add) for my cichlids. they arnt aggressive in anyway and basically just cruise around they tank in a group(4 of them). I have no idea what they are and im more curious as to what they are then anything
