Mine eat frozen foods (mysis, bloodworms, spirulina brine shrimp), romaine lettuce & pretty much any kind of greens (endive, red lettuce, mustard greens, some spinach), and most sliced veggies as well. It took a while, but now they eat pellets. Too bad they were extremely nasty to each other
My shoal feeds on FD plankton, salmon pellets, growth granules, high density granules, algae wafers, cut raw shrimp, earthworm sticks, spirulina sticks, Ken's mixed sticks, different flake foods, sliced kiwi, blanched zucchini, blanched spinach, etc.
