A couple of points I'd like to clarify...
The whole '1cm per litre' thing only applies to small, slim bodied fish that get to less than three inches, adult size, so you can't use it for things like clown loach and discus.
Yes, discus keepers/breeders do feed a lot of food, but they also do massive water changes as well. 50% every other day is not uncommon, and plenty of discus keepers do even more.
