Pretty sure I have ich starting in my tank. Wondering if I can get away with moving all my fish between a 40g and 20g and treating with copper than sterilizing the tanks and keep them in the two tanks for the fallow period in my dt. I have a long nose hawk, foxface, hippo tang, sailfin, powder brown, 6 line, lawnmower ,ywg ,pair of clowns, purple firefish, and royal grammar. The powder brown, foxface and sailfin are the only medium sized fish everything else is small.
