Blue Miyuki Kagami Scale Medaka (青幹之カガミ鱗メダカ)

The Blue Miyuki Kagami Scale Medaka is a beautifully refined variety of Japanese rice fish known for its bright blue dorsal shine and mirror-like reflective scales. This medaka belongs to the Miyuki line, which is celebrated for its iridescent back, but the Kagami Uroko (鏡鱗 or “mirror scale”) trait takes its brilliance to another level.

What is “Kagami Uroko”?

“Kagami” means “mirror,” and “Uroko” means “scale” in Japanese. Fish with this trait have enlarged, highly reflective scales that create a glassy, mirror-like effect along the back or sides. In bright light, the fish shimmers like polished metal — an eye-catching feature for medaka lovers.

Physical Characteristics

• Body Color: Pale to deep bluish tones, depending on the line and lighting.
• Dorsal Shine: Classic Miyuki silver-blue shine across the back.
• Mirror Scales: Enhanced reflectivity from Kagami scales, giving the fish a sharper and more radiant appearance.

Summary

The Blue Miyuki Kagami Scale Medaka is ideal for collectors who appreciate subtle beauty with a metallic edge. Its luminous back and mirror-like scales offer a graceful presence in both outdoor tubs and indoor tanks, making it a favorite among enthusiasts of refined medaka strains.
