Looking for a little advise. I have a pintail that's been in QT for about 39 days now. It went through 2 rounds of prazipro the first 10 days and the rest of the time has been just observation. I'm a little leary of putting him through copper because I hear wrasse's can be senseitive to copper. It has not shown any signs of disease, is eating and swimming normally. I'm Just wondering if the experts here think it would be safe to add it to my display tank, or if I should treat with copper. I have Copper Power on hand if needed.
