I have a tang with ick. He's in the display tank and I was hoping to leave him there. I thought things were going okay, then he started to not to move around as much. He's active again, and has been eating well. I'm soaking his food in garlic. I'm thinking I should move him and set-up a QT tank and do the hyposalinity. I didn't want to do that, because of stress and so forth. Do you think I should do that? If I do, will he just recatch it when returned to the main tank? No other fish in there, look to have it.
