The Gentle Giants of the Koi Pond: Chagoi Koi

Chagoi koi are some of the most popular and beloved varieties of koi fish. These gentle giants are known for their beautiful brown coloration, ranging from light tea to deep chocolate, and their friendly personalities. Chagoi koi are relatively easy to care for and make wonderful additions to any koi pond.

History and Origin

Chagoi koi are one of the oldest varieties of koi, dating back to the Taisho era (1912-1926) in Japan. They were originally called “Ochagoi,” which means “tea carp,” due to their resemblance to the color of Japanese green tea. Over time, the name was shortened to “Chagoi.”

Physical Characteristics

Chagoi koi are typically large-bodied fish, with broad heads and thick tails. Their fins are also relatively large and unsplit. The most important characteristic of a Chagoi koi is its color. The ideal color is a uniform, rich brown with no other markings. However, some Chagoi koi may have a reticulated pattern of lighter scales on their bodies.

Personality and Temperament

Chagoi koi are known for their friendly and docile personalities. They are often the first fish to come to the surface of the pond when food is offered and are easy to hand-feed. Chagoi koi are also relatively peaceful fish and get along well with other koi varieties.

Care and Feeding

Chagoi koi are relatively easy to care for. They require a spacious pond with good water quality. They are also omnivores and will eat a variety of foods, including koi pellets, flakes, and vegetables.


Chagoi koi can be bred in captivity, but it is a delicate process. Breeders must carefully select parent fish with good conformation and color. The eggs are then hatched in a controlled environment and the fry are raised until they are large enough to be released into the pond.
