I feed mine twice a day - mine are 1 -2inches and love eating mozzy larvae, live bloodworm and baby earthworms.
It depends on what you feed them, with mine because they eat live food, it doesn't matter if I put a bit more in with them as they don't foul the water like frozen bloodworm. I usually suck up a few mosquito larvae and a couple of bloodworms morning with turkey baster and drop them in each of their containers, and then add a few more or 2 baby earthworms as well in the evening if it looks a bit empty. Usually their containers are empty by next morning.
