A variant of Koi (Cyprinus rubrofuscus)

White-bodied koi with both red (hi) and black (sumi) markings, the black not appearing on the head. Developed in the Taisho era as a tricolor extension of Kohaku.
Keeper tips for this variant
Sumi black deepens with cooler, mineral-rich water — a stable pond with good KH helps the black 'finish,' while warm soft water can leave sumi grey and unstable.
