The world's first pellet for marine fish that offers an extreme amount of natural algaes. With more than 67% algae, this pellet is devoured by any marine herbivore as soon as it hits the water. Gone are the days of hanging seaweed strips and the mess they leave in your tank. Let Hikari® help you give your marine herbivores and omnivores what they need with little or no fuss. Hikari® Seaweed Extreme™ contains higher levels of natural ingredients which may cause a slight change in color from one production lot to another. Rest assured because of our rigid quality standards each package meets our superior nutritional specifications.
