WHITE KOI with RED and BLACK MARKINGS

Sanke is recognized as a Kohaku with Sumi (black markings) added. Sanke literally means ‘tri color’ in Japanese. Sanke have more varied patterns than Kohaku due to the highly variable Sumi.  Inspection of Sanke can, therefore, begin with observation of red patterns. The Hi markings should be that of a good Kohaku, and the Sumi should be that of a good Bekko. A Sanke head should be free of Sumi.

Sumi markings are roundish and appear above the lateral line. Sumi have different quality according to koi's ancestry. Most generally,  hidden black markings appearing under bluish skin will become glossy, fine Sumi. Taisho Sanke of the Jinbei lineage have massive Sumi of good quality.
