As far as pellets go, I only use NLS, its got a better nutrition make up over hakari, when I saw Hakari gold/staple ect had MSG in it I quit buying it . I have this rule about my animals, If its a chemical I wont eat (anything man made), then neither will they, my chihuahua eats healthier food than the vast majority of people I know. However Hakari Emerald entre, blood worms, Krill and squid are all awsome whole natural frozen foods.
