I bet it's because discus are so expensive, people reccomend keeping them at high temps to prevent disease. Not to mimic their natural climate, more similiar to how pet stores add salt to their freshwater tanks.
I someone knows this to be wrong, let me know. I might keep discus one day. This is just what I've gathered from my own research. Discus do perfectly fine at 80 degrees or so, and that will free up tankmates. Just keep the water pristine.
First on angels and discus, yes, they do occur together is some parts of their respective habitats. But wild-caught angelfish do require warm temperatures, above 80-F, or they do not last. It is only the tank raised angels that manage in the upper 70's.
As for discus needing warmer temps, the reason is explained in our profile, under water parameters. It mentions the trouble that below-80F temp often causes. With discus this applies to wild and tank raised fish.
Many fish seem to be able to adapt to differing hardness (and related pH) after generations of tank raising, but to my knowledge none adapt to temperatures that differ significantly from their habitat.
