Flagfish, perhaps you should start a thread telling us what size your tank is (in litres and/or gallons) and asking about possible stocking. mabey tell us some of the fish you would like to have, even though you know they wont ALL be compatable, so you can get ideas on which of them can go together. I think this is the 3rd thread Ive read from you asking "can I put this fish into this tank" I sure do hope the discus and the BGK wont be sharing the same tank
