The Kumonryu fits into the Kawari group. Kawari meaning non metallic. The Kumonryu is also Doitsu (German) koi meaning that it is scaleless koi. Beni (beni means red) kumonryu have red on them.

Kumonryu have a jet black pattern that emerges like billowing black clouds against a white background.

The black pattern is variable and unstable, disappearing with changes in the water temperature, reappearing sometimes as a completely different pattern.

The pictured koi was bred by Katsumi.
