You can try the epsom salts at 1 TBS per 10 gallons. Do you have a smaller hospital tank? You can try lowering the water to just above the dorsal. I've heard some people have success with Microbe Lift Artemiss for internal infections. It's an all natural expellant and may be available in your area. But, if this is the swim bladder the chances of saving it are slim...
