Well, the title is self descriptive...one of my new paradise fish (Leopold) appears to have a buoyancy problem. He has to move his fins quite vigorously to stay afloat, although his behavior seems largely normal otherwise. He is currently in a QT tank with another new PF, Laura, due to the presence of ich on both fish. Anyhow, is there anything I can do about the swim bladder problem once the ich is dealt with? I was thinking of reducing the water level in the main tank to make it easier for the fish to get air.
