✨ What is “Kagami Uroko”?

In Japanese, “Kagami” (鏡) means “mirror” and “Uroko” (鱗) means “scale.” Kagami scales refer to a special type of scale that reflects light like a mirror. This trait intensifies the shine on the fish's surface, giving it a sharp, glossy look — almost like it's been polished. Under natural sunlight or aquarium lighting, the scales shimmer vividly, distinguishing these medaka from standard Miyuki types.

• Scale Type: Kagami (mirror) scales — highly reflective and smooth
