Asagi are non-metallic koi with a blue-gray reticulated scale pattern and red or orange accents along the lower sides, cheeks, and fins. The regular scale effect is a defining feature. Viewed from above, a clean blue-gray back can appear almost woven rather than divided into large colored plates.

How to Identify Asagi
- A fully scaled blue-gray back with a repeated netted pattern.
- Red or orange associated with the lower body, cheeks, and fins.
- A non-metallic finish rather than the persistent sheen of a metallic variety.

Compare Shusui for the Doitsu counterpart, with smooth-looking skin and rows of larger mirror scales. Shiro Matsuba and Aka Matsuba have different ground colors and dark-centered scale effects. Start with scale arrangement before judging the red; the difference between Asagi and Shusui is not simply how much red is visible.
Choosing and Observing Asagi
Look for coherent reticulation, a balanced body, and red placement you enjoy. The strength of blue-gray and red can develop as the fish grows. Hardness alone cannot guarantee that a fish will darken or that a paler purchase will finish better. Review the actual individual over time and maintain appropriate water conditions instead of changing chemistry to influence its pattern.
