can anyone tell me if melafix treats swim bladder problems? my two firemouths have been fighting for control and the loser has been moved to my hospital tank as it is just sitting on bottom and not swimming. I have treated twice with king british revitalising tonic and am now about to try melafix.I was wondering if his swim bladder is the problem and would melafix help? he has a few nips in his fins too. thankyou for advice
