Medaka with red and white pattern like koi. Each individual has unique markings — every fish is one-of-a-kind.
Kohaku medaka is an improved variety modeled after Kohaku koi, featuring red (vermilion) markings on a white base. Each individual has uniquely positioned and shaped patterns, giving every fish a one-of-a-kind quality. Fixation rate is low — mass breeding with rigorous selection of ideal red-white distribution is key to quality maintenance. White containers with top-view observation best reveal the red-white contrast. Hardy in 5–30°C, neutral to slightly alkaline water. Carotenoid-rich color-enhancing food helps intensify the red pigmentation. Peaceful temperament allows community keeping, though species-only tanks aid pattern selection.
