Hi fish tank friends. Need some advice please. I’ve been dealing with ich for a few weeks now. I’ve already lost a few fish unfortunately. I still have a maroon clown and a purple firefish goby and a watchman goby in the tank. The ich has not effected them at all from what I can tell. My question is should I treat the tank with copper or just let the ich die off on its own. Any help would be appreciated.
