Just keep in mind that most fish will ALWAYS eat. No matter how much they've already eaten. Fish will continue to stuff themselves. They do not need that much food--and will be just fine with lesser amounts. I can't tell you how many people report feeding several times a day, and suffering through algae blooms and water quality issues, and then saying 'Well, the fish looked hungry! and they eat every time I feed them!". Yes, they will eat. But they do not need it. It is worse for them to be overfed.
