Hikari Seaweed Extreme
The original 67% seaweed pellet for marine grazers. Hikari Seaweed Extreme was the world's first pellet made with more than 67% natural seaweed, an ideal supplemental diet for herbivorous marine fish. The highly aromatic pellets soften rapidly in water to instantly attract grazers like tangs, and they work just as well for omnivores such as clownfish, damsels, and butterflyfish. Rich seaweed nutrition supports fast growth, immune health, and vivid color. Round out the diet with the carnivore-focused Marine-A.
