This 11" Kumonryu Butterfly Koi, often referred to as a “Blue Belle,” offers a unique and ever-changing appearance that sets it apart from traditional varieties. The soft blue-gray base is overlaid with inky black sumi, creating a dynamic, cloud-like pattern that gives this koi its signature look.
The doitsu (scaleless) body enhances the smooth, flowing appearance, while a subtle dorsal line of scales adds definition and structure. The lighter coloration seen here represents a transitional phase—Kumonryu are well known for their ability to shift between darker and lighter expressions depending on water conditions and temperature.
The butterfly trait brings an added level of elegance, with long, flowing fins that trail gracefully through the water. This movement, combined with the evolving pattern, makes the fish especially engaging to watch in the pond.
At 11", this koi is in a strong size range with immediate visual appeal and plenty of potential for transformation over time. A great choice for hobbyists who appreciate koi that are both unique and constantly changing.
Kloubec Koi Farm is a family-owned American koi breeder established in 1981. Situated on 80 acres with over 60 outdoor ponds and a 300,000-gallon indoor facility, all koi are raised on-site rather than imported for resale. Each fish undergoes a comprehensive health screening and quarantine process prior to sale, and we have never experienced a case of Koi Herpes Virus (KHV).
