Lame Medaka Body Shape Genetics — Glitter Expression & Body Form Selection

Lame (glitter-scale) medaka feature sparkling scales created by iridophore crystals exposed on the scale surface. Balancing glitter quantity with body shape is the key selection challenge.

Glitter Expression Mechanism

In normal medaka, iridophores sit beneath the skin surface. Lame medaka carry a genetic variation that pushes iridophore crystals to the scale surface, creating visible sparkle.

Glitter Selection Criteria

Density (more glitter per scale), size (larger particles preferred), distribution uniformity (even coverage across the body), and color variety (gold, silver, multicolor).

Body Shape Challenges

Lame medaka are prone to body shape deterioration. Pursuing glitter quantity alone neglects body shape selection. Spinal deformities appear in some lines. Always prioritize individuals excelling in both glitter AND body shape.

Breeding Strategy

Lame x lame generally produces lame offspring. Introduce good body-shape individuals from separate lame lines for outcrossing. F1 may have slightly reduced glitter, but F2 recovers.
