I have had two Discus stop eating lately. I kept them in the tank, but separated them with a divider. I actually had to put one to sleep today with clove oil and cold water, because it was lying on the bottom sideways 
I had been treating the tank with Polyguard, because it treats a huge spectrum of fish disease and I had no clue what had caused two of my fish to stop eating. All the others still have a healthy appetite.
I still have one sick fish. For a period it looked as if one fish had Ich, another almost looked like it had Velvet. I haven't noticed it anymore. The temperature was at 28C but I turned it back up to 30C. Water stats are fine.
I am at a loss. I really am. I have no clue whats wrong with the non eating fish, as it is showing no external signs of disease.
Think I will try some Praziquantal. Does anyone have any ideas as to what this mysterious illness could be? My only problem is that the other fish are showing no signs of illness...
