I give mine New Life Spectrum Community formula, Dainichi Veggie FX, Ultima, and Veggie Delight, Ocean Nutrition Cichlid Veggie Flakes, some freeze-dried krill or frozen mysis occasionally, and sometimes they're in the mood for some peas. I feed once a day, when I get home from work, whenever that is, and I try to mix things up, offering a different food than the day before.
Gawd, my fish eat better than I do.
