Kumonryu (koo-mohn-ryoo): The Kumonryu is a mysterious and captivating koi variety, best known for its ever-changing black and white pattern. Named after a legendary “dragon of clouds and water,” the Kumonryu embodies fluidity and transformation—its sumi (black) markings can shift, fade, or reappear over time, making each fish truly one of a kind.
This Doitsu (scaleless) koi has a clean, glossy skin that enhances the contrast between its snow-white base and bold black patches. Some Kumonryu remain stark black and white, while others may develop hints of gray or subtle shadowing, especially as water temperature or seasons change.
Kumonryu are ideal for koi keepers who appreciate unpredictability and living art in their ponds. Watching their patterns evolve year after year is part of the joy of owning this dynamic variety.
