Best of luck. We had a yellow-eye tang that was coated in ich. We tried to wait it out as he was eating well and we didn't see him rubbing up against rocks or have any troubles breathing. Well, he didn't make it. After that, we set-up a 40 gal QT tank so we can properly treat all fish. Two of our other fish ended up with a little ich from the tang so we put the whole gang in the QT and treated with hyposalinity. They are all happy and healthy. But dag - I sure liked that tang. :/
