Blue body color combined with hikari body type. Bluish body with silvery-blue external light creates cool and fantastical beauty. Especially beautiful in outdoor sunlight.
Ao Hikari medaka combines blue body color with the hikari body type (symmetrical dorsal and anal fins, broad caudal fin). Blue-tinted body color combined with silver-blue external dorsal light creates a cool, fantastical shimmer. Many strains derive from Marine Blue and Miyuki crosses, where external light and body blue synergize in beauty. Top-view observation shows the light band crossing the blue body, evoking a clear summer sky. Especially beautiful under outdoor sunlight. Hikari body type is highly heritable; external-light-range selection in breeding improves quality. Extremely hardy in 5–30°C, neutral to slightly alkaline water. Easy to keep and breed — a popular entry point into blue medaka varieties.
