Selective breeding miyuki medaka for full-body sheen: light extension scoring, parent selection criteria, fixation rates, and container color effects.
Miyuki medaka's greatest appeal is the beautiful body sheen extending from back to head. Here's how to selectively breed for full-body coverage.
Point light (scattered spots) → Weak light (partial coverage) → Strong light (50%+ coverage) → Super light (full back coverage) → Full-body (head to tail complete coverage).
Breed full-body or super-light individuals together. Evaluate "thickness" of light (thick sheen preferred over thin). Prioritize body shape alongside sheen quality.
White or light-colored containers enhance sheen expression. 25-28C is optimal. Avoid overcrowding (stress suppresses expression). Moderate sunlight activates iridophores.
Full-body x full-body crosses over 3-5 generations progressively increase fixation rates. Watch for inbreeding-related body shape deterioration.
