This 10" Kumonryu Koi features a bold and classic black (sumi) and white (shiroji) pattern, creating strong contrast and a clean, timeless appearance in the water.
The sumi is well-defined and distributed across the body, forming a dynamic pattern that stands out clearly against the bright white base. The balance between light and dark gives the koi a striking, high-visibility look from every angle.
As a Kumonryu, this koi is known for its changing pattern, with sumi that may shift, intensify, or recede over time. This natural transformation adds ongoing visual interest, making the fish feel unique and evolving as it matures.
The Doitsu (scaleless) body enhances the smooth, glossy finish, allowing the contrast between black and white to appear sharper and more defined. A clean dorsal line adds structure while maintaining the sleek, modern look that Kumonryu are known for.
At 10 inches, “Onyx” offers strong presence and excellent growth potential, making it a great addition for hobbyists seeking a high-contrast, ever-changing centerpiece koi.
Kloubec Koi Farm is a family-owned American koi breeder established in 1981. Located on 80 acres with 60 outdoor ponds and a 300,000-gallon indoor facility, we raise our koi on-site and do not import fish for resale. Every koi completes a comprehensive health and quarantine protocol before being offered for sale, and we have never experienced a case of Koi Herpes Virus (KHV).
