Most likely you already had ich in your tank. It's probably just a coincidence that the tang got ich some time after you added the coral. Most display tanks do have ich,you just don't see signs of it until the fish get stressed in some way.

The only sure way you don't have ich in your tank is if you followed the steps mentioned in the article for every piece of livestock in your tank.
