TetraPro™ Tropical Crisps provide advanced nutrition for the discerning fish-keeper. This nutritionally balanced diet feeds cleaner than ordinary flakes, leaving behind less waste in the aquarium and in the can. Each crisp is made using an exclusive low-heat process which preserves essential vitamins for a healthier, more nutritious diet. TetraPro Crisps float longer to allow fish more time to eat and are precision crafted with Biotin to support fish immune system health.
