The Kujaku is a metallic or Ogon koi with the reticulated net-like pattern of the Asagi on its
back. This is overlaid with either a gold, yellow, orange or red
Kohaku-type pattern creating a striking effect.
Remember to stop feeding your fish when the water temperature in the pond drops below 50 degrees Fahrenheit. The metabolism of the fish slows drastically at this point and the fish cannot properly digest food.
