Tetra Variety Wafers are a Complete food for all bottom-feeding fish and crustaceans. Mix of sinking herbivore and omnivore wafers to meet the nutritional needs of different bottom-feeders. Enriched with vegetable proteins and Spirulina algae. Wafers allow fish to graze naturally. Especially suitable for more timid bottom-feeders who need time to feed. Small wafer size reduces competition, allowing all fish to feed. Less waste for cleaner, healthier water.
