Howdy Crew, I’ve recently purchased a 4″ long Harlequin Tusk. After about 5 days in QT it was showing signs of ich. I waited a couple of days to see if it would clear up on it’s own and it did not. The fish never stopped eating and was acting normal. So I read up on treating them for ich and saw on WWM that you can use copper but that in too high of a concentration, will cause them to go blind. I decided to go ahead with the copper as the ich wasn’t getting any better. I used Mardel Copper Safe and treated with less than the bottle prescribed hoping the tusk wouldn’t go blind. This was yesterday and at feeding time last night, the fish was swimming around looking for food but wasn’t really finding any. I think he’s gone blind. My question is, can a tusk regain their sight? I immediately put a bag of carbon in the filter to remove the copper and did a 1/3 wate
