Discus gone blind

[annj]

I have discus I have bought from Hans. My blue diamond is 5" and all has been good untll last few days. Noticed he stays in corner of tank. Put net in to catch and see if I could detect any harm and his eyes of white and cloudy. He appears not to see. Sometimes he eats and sometimes he doesn't. I know the Cobalt has
been dominant and strikes all the other 5 I have. Could he have hurt this discus??? Anyone have any ideas.
