Multicolored glitter scattered across body radiates like fireworks. Lame changes to rainbow colors with light angle. Rapidly gaining popularity as a summer icon.
Hanabi (fireworks) medaka is a showy improved variety whose scattered lame scales burst radially like fireworks across the night sky. The multi-colored lame shifts through rainbow hues with viewing angle, and from above it looks like grains of light dancing on the water — a popular choice for summer coolness. Standard body type, roughly 3–4 cm. Lame density and color expression vary between individuals, so selective breeding maintains and improves well-colored strains. Hardy across roughly 5–30°C in neutral to slightly alkaline water. Lame stands out most in dark containers and under direct sunlight or LED light, making it well suited to outdoor keeping and bright settings. Peaceful and community-compatible, though single-variety keeping best showcases its beauty.
