Neptune (White) – ネプチューン（白）

A pure and luminous expression of the Neptune line

Overview

The Neptune (White) Medaka – ネプチューン（白） is a stunning variant of the original Neptune strain, characterized by its clean white body and shimmering iridescent scales. While detailed official documentation is limited, this variety is gaining popularity for its elegant, pearl-like appearance that glows under light.

Background and Lineage

• Base Strain: Neptune Medaka (ネプチューンメダカ)
• Developer: Medakaya Savannah (メダカ屋サバンナ)
• Release Year of Original Neptune: July 2023
• Region: Saitama Prefecture, Japan (埼玉県)

The original Neptune Medaka was created by combining notable strains like Miyazakura, Saboten, and Himitsu Heiki, resulting in a medaka with brilliant blue lame (iridescent sparkle), fin glow (ヒレ光), and aurora traits. The white variant, ネプチューン（白）, appears to be a carefully selected offshoot that emphasizes a pale, translucent body while preserving the luminous features of its lineage.

Key Features

• Pure White Body:
  Unlike the deep ocean-blue tone of the standard Neptune, this variant features a soft, milky white base that reflects light beautifully. It often appears almost pearlescent.
• Iridescent Lame (ラメ):
  Fine, glittering lame scales spread across the body, visible under both natural and artificial light.
• Fin Glow (ヒレ光):
  A delicate glow is often seen in the fins, especially in well-bred specimens — contributing to a celestial, floating impression.
• Aurora Influence (オーロラ系):
  The subtle transparency of the scales adds depth and a layered shine typical of aurora-type medaka.

Conclusion

ネプチューン（白） is a breathtaking medaka variety that captures both refinement and radiance. It’s a perfect choice for collectors who appreciate clean aesthetics, top-view beauty, and the gentle sparkle of high-grade lame. Whether in a pond or a glass bowl, this medaka shines with quiet elegance — like moonlight on water.
