Sanshoku Lame Medaka appraisal
A composite-trait variety with multiple body colors (red, white, black, etc.) plus metallic-sheen scales scattered throughout the body. The balance of body color and density/distribution of metallic sheen determine the evaluation.

What determines the price
Density and distribution range of metallic sheen.
HighThe higher the density of metallic sheen scattered throughout the body, the higher the evaluation. Individuals with dense, widespread metallic sheen across the entire body are preferred over those with it only in specific areas.
Three-color distribution balance.
HighWell-balanced distribution of multiple colors (red, white, black, etc.) is the key to beauty. When weighted too heavily toward one color, the character of the three-color variety diminishes.
Pattern clarity.
MediumThe clearer the color boundaries and the more the pattern is recognizable as such, the higher the evaluation. Blurred boundaries may indicate the characteristics of the three-color variety are not fully expressed.
Strain Stability
MediumThe three-color composite trait requires stable lineage management; lines where characteristics are readily reproduced in offspring are highly valued.
