I have a black molly with dropsy. It looks bad and ugly. Poor fish. He used to be big (about 3 inches) and beautiful and his scales use to look like velvet. When I notice the dropsy the other mollies were constantly swimming underneath him and picking or nipping at the fin below him. He's in a 10 gal quartine tank now. Seems to swim ok and eat. I can't believe how ugly this diease looks with the scales sticking almost straight out and his eyes all buldged. Awful. I feel bad becuase I know his chances are slim. So my question is what kind of anti-biotic should I try? I am at work now but will pick some anti-biotics up right after work. I need some help on any names of anti-biotics. Any advice. I know.... I am keeping his quarentine clean and pristine. By the way the tank readings were Am = 0 Nitrite = 0 and nitrate = 15 ....all other fish in the tank are healthy.
