They are sensitive to a tank that is not established fully or maintained enough. They're not forgiving for someone who doesn't keep up on the tank or is just starting a new tank - they do need stability.
If you get small (aka more affordable) fish you need to feed more and do more water changes due to that. From what I've read, they recommend new to discus people starting with larger fish, like 4-5" if I recall correctly. Then you can just feed 1x/day and do something like a 50% water change weekly. Some still do more water changes than that, though. It's sort of a see how the water parameters do and be prepared to increase WC if they start to deteriorate.
The "Simplydiscus" forum is a great resource, like this forum.
