If they haven't gone through QT (with medications) - IMHO, it takes the disease issue out of the equation for future fishNo doubt I will still keep them in the QT for the next three months however, I was just wondering whether or not I should start the copper treatment. I guess it doesn’t hurt, I just wouldn’t want for them to go through unnecessary stress if it weren’t the case. I just wish there was an easier way to discern 100% if this is ich or not.
