I hate to say it but, I just looked at the thread for the first time and i think you don't have a problem with health but rather a problem of type. I think you might have a red texas that is just starting to peel. When I looked at the first pick I could see the scales where the fish was yellowish in coloration. So if the scales are intact then the peeling "they" were refering to is most likely the peeling of the color on the fish. If it continues to get more yellowish then thats most likely the case.
