Hikari Medaka is specially formulated for Japanese rice fish (Oryzias latipes) and is available in three versions: Baby, for fry; Next, for healthy Medaka growth; and Breed, for optimal breeding. Floating food is recommended for Medaka, as they generally swim near the surface and readily accept floating pellets. The pellets quickly spread across the surface, allowing all fish to benefit. A 2-year Pick-up & Replace guarantee ensures maximum safety and worry-free use.
