That was why I got the cories, but I got the syno cat before I knew anything about discus. My cories got some crazy fin rot that eventually killed them. It started w/ their barbells, and eventually ate their faces! Kind of traumatic. Not sure I want to go through that again, but I do like them.
They all died from the same thing? I'm not sure that would happen again if you have good water in there. If discus are doing well, then the corys should be good too. Maybe it was a freak occurrence. Odd......
