Beautiful blues and reds are trademarks often found in one of the oldest varieties of Nishikigi (Koi) – Asagi. An Asagi Koi will have blue reticulated scales above the lateral line (on top) these blues can range from lighter shades to almost a deep navy. With a light or white outline, if the blue scales are lined up right they will form a beautiful net-like pattern. The underside will have red or deep orange color which may also be found on the fins, gill covers, and mouth.

For the more serious hobbyist, perfect reticulation of the scale pattern with balanced, sharp and uniform accent coloring, and an
unblemished head will make for a more desirable specimen.
