Bettas have small stomachs and therefore should only be fed a pinch of food once or twice a day. Nutrafin basix Betta Food is specifically formulated for bettas. The freeze-dried red grubs are highly nutritious and will be voraciously consumed by bettas. The pellets come in a convenient shaker for easy feeding. As a general rule, aquarium fish should be fed a varied diet containing freeze-dried foods like Nutrafin basix Blood Worms. Bottom-feeding species should be fed Nutrafin basix Staple Food Tablets. Format: small tin, 5 g (0.1 oz)
