I dont know whats goin on, he was I've had him for almost 4-5 months now, i woke up this mornin and found him on his side and thought that he was dying, but then he got up, chased my bala, and then stopped to rest, whenever he stops moving, he starts to flip onto his side, and he's having erratic swimming, i think its a swim bladder problem, any suggestions/remedies?
