Sasya × Hakuhime Medaka – 紗々×白姫メダカ

Sasya × Hakuhime Medaka – 紗々×白姫メダカ A refined evolution of the white-rimmed lineage, born from contrast and careful crossbreeding OverviewThe Sasya × Hakuhime Medaka is a beautifully engineered ornamental medaka variety created by crossing two renowned strains: Sasya Medaka (紗々メダカ) and Hakuhime Medaka (白姫メダカ). This hybrid was developed to enhance visual contrast—specifically, to emphasize a darkened head set against a bright white body, creating an elegant and modern refinement of the original Hakuhime line. In essence, this medaka is an “upgraded Hakuhime,” enriched with depth and structure. Parent Strains Why Sasya × Hakuhime?This cross was carefully selected to combine the best features of both lines: The result is a medaka with a darkened head that anchors the appearance, and a bright, elegant body that shimmers under natural light. This pattern sharpens the silhouette, especially when viewed from above, offering a high level of aesthetic appeal. Comparison Example: Wazumi vs. Wazumi AA similar breeding concept can be seen in the Wazumi A Medaka, which is an enhanced version of the original Wazumi strain. Wazumi A was created by crossing Wazumi with Orochi, resulting in deeper and more consistent black coloration. Likewise, Sasya × Hakuhime aims to bring out the full contrast potential of the white body by anchoring it with darker head tones—serving as a more advanced evolution of the Hakuhime line. Key Traits of Sasya × Hakuhime Medaka Breeding & Care Tips ConclusionThe Sasya × Hakuhime Medaka exemplifies how thoughtful crossbreeding can create meaningful progress in ornamental medaka strains. By merging the classic elegance of Hakuhime with the bold definition of Sasya, breeders have created a modern white medaka with depth, contrast, and graceful brilliance. It is a premium choice for those seeking a refined version of a beloved lineage. Sources / 出典:
