My Cory's get a random combination of shrimp pellets, sinking wafers, algae wafers and NLS Thera+ 1mm pellets twice a day. I don't have to feed them lights out.
The guppies and quarter-sized angelfish that cohabit the tank all eat right along with them, which I don't mind, because my angelfish refuse to eat flakes as a staple, so they get their variety by being fancy-faced bottom feeders. I find it fascinating to watch all of them sit in the corner sharing a meal. The more intelligent (or lazy) angelfish sit above the group and pick off bits that float up from the Cory's aggressive eating. All they were eating prior was frozen brine shrimp and frozen blood worms. They wised up and started eating the food off the bottom that was intended for the Cory's after I fasted them off the frozen stuff. Fasting failed to get them to eat the flakes where I was giving them just a little bite of flakes after 2 days of starving them (which they spit out), but they started eating off the bottom, so I gave up on flakes for now. I'll try again later when they get older.
In the meantime, every fish gets more than enough food. The mid to top dwellers can't eat pellets in one bite because they're all small, so they all slowly pick at the food until it's gone. If I had bigger fish that could swallow their wafers and pellets whole, then I guess my experience would be different.
