I have a 125gallon and I noticed one of my fish has ich... in my tank I have live rock and sand with some mushrooms,polyps, and emerald crabs,snails, and hermits... Can I treat the whole tank with a copper treatment or will it kill the other stuff? If I do a QT will the ich still survive off of the other living stuff in the tank? Whats the best method I heard some garlic stuff or just do a QT with copper treatment?
