Hello, I recently (3 days) purchased 5 new fish (mated pair od BW clowns, Flame, Coral Beauty and wrasse, all are in a 40 gal QT. I just noticed that my Coral Beauty looks like it might have Ick. I made the mistake previously of trying copper treatment which killed a lemon peel. I'm assuming the entire tank is going to be effected so does it make since to setup another QT and transfer the CB into a separate tank? My plan is to try the salinity treatment.
