About
Tricolor lame medaka is a spectacular improved variety combining red, white, and black tricolor patterning with glittering lame scales derived from iridophores. Its koi-like grandeur was one of the driving forces of the improved medaka boom. Each individual has unique color placement, giving them a one-of-a-kind quality. Fixation rate is low — producing ideal tricolor distribution and lame density requires mass breeding and rigorous selection. Black containers emphasize lame sparkle; white containers are better for pattern inspection. Neutral to slightly alkaline water, 5–30°C. Peaceful temperament suits community tanks, though species-only keeping aids quality maintenance.
