They should be fed a Pelet food for 60% of their diet, that should be their MAIN food, and everything else are prety much snacks. I feed my O, Omega one pelets, hikari staple pelets, tetramin jumbo sticks, Freezdried JUMBO krill, meal worms, crickets, earth worms, nightcrawlers, shelled peas, oranges, bananna, and the occasional moth that I catch, grasshoppers.....ect. Hope this Helps!!!
