Chagoi are non-metallic brown or tea-colored koi. Their shades can range from lighter olive-brown tones to deeper brown, so the name does not describe one exact paint color. They are often appreciated for their substantial appearance and reputation for calm feeding behavior, although individual temperament varies.

How to Identify Chagoi
- One principal brown or tea-colored body tone.
- No separate gray background and brown patches of an Ochiba.
- A non-metallic finish; Ginrin examples may also have sparkling scales.
Compare Similar Varieties
Compare Soragoi for a gray fish and Ochiba Shigure for gray combined with brown markings. A Chagoi's apparent color changes with water, light, and camera balance, so compare similar photographs. The single-color impression and finish are more reliable than a sales adjective such as friendly or jumbo.
Choosing and Observing Chagoi
Chagoi can become large, but a variety name cannot guarantee an individual's eventual length or willingness to hand-feed. Assess adult swimming space and system capacity before purchasing. Look for a smooth body line, intact scales, and a color you enjoy. Ask about age, current size, feeding history, and behavior rather than selecting from growth promises alone.
