Lumina Medaka (ルミナメダカ) – A New Star Among Japanese Rice Fish

The Lumina Medaka (ルミナメダカ) is an exciting new ornamental medaka variety whose name means "light of the stars." This poetic image perfectly captures the shimmering elegance this strain brings to aquatic collections.

🌟 Breeding Background

The Lumina Medaka was developed by Muchuu Medaka (夢中) and released in July 2024. It was created by crossing two distinguished lines: Himitsu Heiki (ヒミツヘイキ) and Hibiscus (ハイビスカス). From this union, a brilliant light-bodied variant (光体型) emerged, further refined with both Swallow (スワロー) fin traits and combinations of Wide Fin and Long Fin expressions.

The strain inherits the base body colors from the original Himitsu Heiki and Neptune-type medaka (ネップチュン系), resulting in striking, luminous colorations ideal for both display and breeding projects.

🎨 Key Features

• Name Origin: "Lumina" signifies "light of the stars," emphasizing its radiant presence.
• Body Type: Light-bodied (光体型) medaka with graceful movement under lighting.
• Fin Variations: Swallow fin, Wide Fin, and Long Fin expressions being actively developed.
• Base Coloration: Inspired by the color tones of Himitsu Heiki and Neptune lines, offering deep, clear shades.

🛠️ Development Notes

The breeder notes that while Lumina Medaka is in its early release stages, continued refinements are underway to stabilize the line. Official broader releases are anticipated soon, showcasing improved fixation of both body color and fin traits.

Initial batches may show variation in fin expression, but over the coming breeding seasons, the aim is to fully establish Swallow, Wide Fin, and Long Fin types within the Lumina line.

✨ Conclusion

The Lumina Medaka captures the dreamlike beauty of starlight within a medaka form. With its enchanting shine, diverse fin expressions, and deep coloration, it stands poised to become a favorite among collectors and breeders seeking something both elegant and dynamic.
