Fish Fungus

    Hello all. Recently I switched to a sand substrate, and five days later I've noticed a white growth coming from one of my cory's dorsal fin. It looks like cotton, which leads me to the conclusion that he has some sort of fungal disease. He probably got injured in the net when I took all the fish out (cories are fast when they want to be :p).

    I'm thinking a salt bath would do the trick. I think I've caught it early. How much aquarium salt and water should be used in the bath? Is 20 minutes a good amount of time? What do I do if he passes out? Advice is welcome.

    UPDATE: Okay, we have a bigger problem on our hands. One of my balloon mollies is dead on the filter intake, covered in white patches that appear to be fungus. I'll get a better look when I take him out. Many fish were picking at the intake and I didn't see him since he's jet black.

    I'm freaking out. Could my whole tank be infected? PLEASE HELP!
