Discus Fish Not Eating

This is the photo of the rather healthy fish is this a healthy discus?

nope he's a gonner. look at his clamped fin and lethargy. ... not looking good dude, also the eyes say it all... hes obviously in a lot of stress....

im gona regret comin online while smashed but oh well. as said dude. if they do survive the damage is already done

This is the blighter in my tank that has now decided to go on a hunger strike...... I'd hate to loose him/her.... It's been (more or less) 7 days now since he/she's had a decent meal......

have you tried to worm them , tried to keep discus last year bought 8 all went same way as in your pictures , only have 1 left , never again , Tom
