OK so my BGK is going on his fifth day sense coming home and is doing well from what i can tell. Hes currently in a 29G grow out until February and is only about 3". Right now im feeding him blood worms exclusively and I would like to vary his diet a bit but money is tight so something on the less expensive side is preferable. I would also like to know what size tank I should upgrade to as im hoping he can live in it for the rest of his life. Ideally it would be a community setup with a few different species so I would also like to know what would make good tank mates in the future?
