Kōhaku Lamé Medaka – 紅白ラメメダカ

Traditional elegance meets a sparkling modern twist

Physical Characteristics
The Kōhaku Lamé Medaka is a graceful ornamental variety that draws inspiration from the iconic Kōhaku koi—featuring bold red and white coloration—while adding a contemporary shimmer through lamé (glittering scales). This beautiful balance between tradition and brilliance makes the variety especially prized by collectors.

• Body Color: Bright white base with deep red-orange markings arranged in a clean, symmetrical pattern
• Lamé (Glittering Scales): Iridescent glitter scattered across the body, adding sparkle and depth
• Scale Type: Non-transparent, enhancing the opacity and boldness of the color blocks
• Visual Appeal: Particularly striking from the top view; the lamé glimmers like scattered stardust on a Kōhaku canvas

Origin and Development

• Year of Development: 2016
• Original Breeder (作出者): Seiraku-an (静楽庵)

The Kōhaku Lamé Medaka was established by breeder Seiraku-an in 2016. It originated from the Sanshoku Lamé Mikiyuki line but was refined by removing the black elements, leaving only the red and white—a process that emphasized the classical koi aesthetic. To enhance the glow and contrast of the white areas, Aurora-lineage genes were introduced, leading to a unique medaka that combines vivid coloration with internal luminosity.

One of the most impressive challenges in developing this variety is fixation. Achieving clear red-white balance with pronounced lamé has an estimated fixation rate of only 10%, meaning extensive selection and patience are required over several generations.

Breeding Notes

• Red markings may vary in shape and placement—select for symmetry and depth
• Lamé tends to improve as the fish matures, becoming more noticeable over time
• Breeding focus should be placed on individuals with clean white backgrounds and vibrant lamé glitter

Conclusion
The Kōhaku Lamé Medaka offers a perfect blend of old and new. It brings the elegance of Kōhaku coloration into the modern medaka world with its sparkling lamé. For breeders and collectors alike, this fish represents a rewarding challenge and a brilliant addition to any viewing bowl or pond.
