Hikari Tropical Mini Algae Wafers are specially designed for herbivorous fish, including Plecostomus, snails, crustaceans, and other algae-eating species. This sinking wafer is packed with a perfect balance of premium-select vegetables and proteins to support healthy growth and desirable form. The formula includes pure-cultured spirulina and chlorella algae, which enhance vibrant coloration and provide essential nutrients. The unique disc shape sinks quickly while retaining its form, allowing even less aggressive species to access the food over a longer period.
