Hi, We have 4 Barbs, 5 Clown Louchs, 2 Gouramie's and 3 Pleco's and 1 Guppy....... Question is We just threw in a Betta, at first every fish was nipping on the betta's tail, i threw in a cube of BLOODWORMS, Everyone ate, and they left the Betta alone... is it ok that the betta Remains in this aquarium? Or will that be a problem?
