Also known as: Persimmon-Colored Night Sakura Medaka

柿色夜桜メダカ – Kakiiro Yozakura Medaka

Persimmon-Colored Night Sakura Medaka

Overview

The Kakiiro Yozakura Medaka (柿色夜桜メダカ), also known as the Persimmon-Colored Night Sakura, is a selectively bred ornamental medaka variety developed from the well-known Yozakura Medaka (夜桜メダカ) lineage. With its refined persimmon-orange hue and dazzling lame (iridescent glitter), this strain offers a fresh take on a classic medaka favorite.

Origin and Background

  • Year of Development: 2020
  • Original Breeder (系統作出者): Takayasu Ōba (大場 貴保)

This variety was established through linebreeding from Yozakura medaka, with breeders specifically selecting for individuals that displayed a warmer, more vibrant persimmon (kakiiro) tone. Over time, this orange tone was stabilized along with the semi-transparent and glittering traits.

According to reports from Medaka no Yakata, even within the Yozakura line, certain individuals showed a noticeable persimmon tone. These were carefully selected and fixed over successive generations, eventually giving rise to the distinct “Kakiiro Yozakura” strain.

Key Features

  • Body Color:
    Deep orange reminiscent of persimmon, combined with black shading on the dorsal side for contrast
  • Scales:
    Semi-transparent base with scattered lame (glittering scales) throughout
  • Visual Impact:
    Especially brilliant in top-view tubs, but equally beautiful in side-view tanks
  • Lineage:
    Derived from Yozakura Medaka via selective breeding for warm coloration

Breeding Notes

Because the Kakiiro Yozakura shares its roots with Yozakura Medaka, breeders still observe some variation in color expression. To maintain the unique orange tone and glitter balance, it is recommended to:

  • Select breeders that display clear persimmon coloration
  • Focus on individuals with balanced lame distribution
  • Maintain and improve fixation through consistent linebreeding

Conclusion

The Kakiiro Yozakura Medaka is a refined evolution of the Yozakura bloodline — glowing with persimmon warmth and glittering charm. It represents the beauty of Japanese medaka breeding, offering both visual appeal and genetic depth. Whether you’re a collector or a serious breeder, this variety adds a unique splash of seasonal elegance to any tank or tub.
