Alright, I have no idea what I'm talking about. I noticed that the 2 fish (heniochus) looked bad, and he assumed it was ich. He's at Wal-Mart right now trying to buy a QT, but it's only going to be a 10 gallon tank. Don't know if that's going to be big enough for all of the fish he has. They are: purple firefish, diamond goby, and 2 clown fish. Also, the clown fish have been breeding so he doesn't want to stress them out.
