Tropical Marine Power Garlic Formula Granules are sinking granules designed specifically for ornamental and omnivorous marine fish. Tropical has carefully balanced this formula for every day nutrition, and it also may be used as a supplementary food for fish needing more garlic in their diets. Garlic is a natural immune system stimulant that has also been shown to have a significant impact on the digestive capabilities of fish. This makes this food an excellent choice during periods of medical treatment, convalescence, quarantine, and acclimation periods.
