I wish that I could give you some kind of definitive answer, but unfortunately that's only going to come from a vet, and only if they take a sample & put it under a microscope.
Generally when a fish refuses to eat, and begins to shed its intestinal lining, it's indicative of internal parasites. But at this stage of the game I have no idea if that is the problem with your aro, or if sometihng else is going on? Sorry that I couldn't be of more help.
