So I go take a look at my tank yesterday and see my yellow tang and blue hippo tang both have ich. My tank has been running for over a year now nd I have never had any problems with ich. The last thing I added to my tank was a refugium a bought from jessy. I know a few of her fish had ich. Could htis have brought it over to my tank? I have been feeding them sea weed with garlic, will this help it out?
