I feed very little unless breeding, and always fast them at least two days a week, also keep temperatures low (about 72F). This allows the fish to live much longer because they don't have a high metabolism rate. They are still very active.
IMHO most people overfeed because they don't know any better, and many people who do know better STILL overfeed because they like watching the fish eat, which is selfish.
