Kumonryu koi stand out compared to other Koi fish because of their striking black-and-white coloring and the changes they undergo over time. These Koi are scaleless (Doitsu) with a black jet-sumi pattern that can shift or disappear during changing seasons. Their bold black markings rest atop a clean white base.
The term “Kumonryu” means “dragon of clouds,” reminiscent of the floating patterns placed upon the scaled fish, resembling a dragon floating through mist. One of the most fascinating aspects of these Koi is their ability to change colors. The fish's black markings may increase or fade depending on their surroundings, such as the water temperature. This creates a living canvas ready to be displayed in any pond.
