Don't know what I do that causes double posting, but I gotta stop it.
What you describe sounds like hikkui, particularly since you can scrape it off with your fingernail. Again, that's something I have no personal experience with. But, I have seen what is called hikui in both koi and discus (not so sure it is the same thing, but does have similar sort of appearance). I know no cure for it. A mutual acquaintance has put up with it for years now on a single fish. No transmission to other fish at all. Kodama's website sells stuff that is supposed to work, but I do not know anyone who has had success with it. Also, the areas where hikui appears tend to become faded, so there is a discoloration that could be disfiguring in some cases. So, I'm no help at all!
As for whether hikui will disqualify a fish from a show, I'll leave that to others more knowledgeable. I personally would want to disqualify any fish showing symptoms of illness, but I know that does not always occur.
