Sudden Death?!?

Hi everyone,
This morning i woke up as usual to feed my discus and I noticed one of them was on the floor completely pale and dead. My other ones seemed fine and are eating. I always noticed the one that died was a little skinny but thought he would get over it, he was eating....did I do something wrong? :'(

From the little you wrote, it's really hard to tell what happened. Was the fish eating and swimming about? Had it had any other symptoms besides being a little thin? There could have been a lot of things which killed the poor guy.
