Komachi Medaka (小町メダカ – Komachi)

An elegant Kohaku medaka named after a legendary beauty

Overview

The Komachi Medaka (小町メダカ) is a refined ornamental strain developed in 2018 by breeder Kunio Ono (小野邦雄氏). Named after the iconic Japanese poet and beauty Ono no Komachi, this variety is admired for its elegant Kohaku-style coloration — a beautiful contrast of deep red and pure white — and its non-transparent scales that bring out richer, more defined color expression.

Key Features

• Body Coloration: Vivid red markings on a clean white base — traditional and highly prized in Japanese aesthetics
• Scale Type: Opaque, non-transparent scales that give the body a solid, crisp appearance
• Special Traits: Some individuals may show external light (体外光) or lamé, adding shimmer and depth
• Overall Aesthetic: Refined, balanced, and elegant — true to the name “Komachi”

Fixation Rate & Breeding Notes

The fixation rate for the classic red-on-white Kohaku pattern in Komachi Medaka is relatively low, which means breeders will often see a variety of expressions in offspring — including solid red, solid white, and mixed patterns.

This makes line selection crucial for breeders aiming to fix the ideal contrast and distribution of red markings over a white base. While challenging, it also provides exciting opportunities to select and develop your own sub-lines within the Komachi strain.

Conclusion

The Komachi Medaka beautifully represents the fusion of art and genetics in medaka breeding. With its soft red hues, crisp white base, and graceful balance, it brings traditional Japanese elegance into your aquarium.
For collectors who value subtle beauty and enjoy the creative challenge of selective breeding, Komachi is a timeless and rewarding choice.
