salt is the opposite of soothing, it works by irritating the fish's skin so that it develops a thicker slime coat. it's the thicker layer of slime coating that initially protects against disease. it's the equivalent of you getting a callous on your finger - it eventually protects you from constant irritation, but it's irritation that put it there in the first place.
