For what it matters I feed small amounts twice a day. It seems common sense to me and comes much closer to mimicking the way small reef fish feed in the ocean( constantly picking at food sources). Groupers, eels and other predators I would handle differently. I also enjoy watching them eat. With all my hermits and coral banded shrimp nothing seems to go to waste. If the water becomes toxic atleast they will die fat and happy, the same way I plan to go.
