I bought a blueface angel from a local marine store for really cheap because it had a hole in its head. The store said that the hole has been there for awhile and it wasn't healing because there were no live rocks in the tank and the water qaulity of the tank wasn't exactly perfect. Now that I bought it, I do have live rocks in my tank and my parameters are good. How will this hole on the fish go away? any treatments that doesn't involve medication because I have a couple of corals in the tank and inverts also.
