also the main display is infected as well. Any water/sand may contain the eggs of the disease. Only way to know for sure it is gone would be to remove all fish from display for a long period of time to break the cycle. Otherwise even if you cure the tang in Qt, putting it back in the display could result in it re-acquiring ich.Isolation in QT and copper is probably the way to go.

what other fish are in the main display?
You can use Rid-Ich in the display as I have done this. The corals will freak out so be prepared to do many water changes if you go this route. Even in fish only tanks you must change the water between dosages.
