Asagi are fairly classical from a genealogical point of view, and constitute a very tasteful variety. They usually have blue on the entire back and Hi on the belly, pectoral fins and gill covers.
The scales on the back have whitish base and thus collectively give an appearance of meshes of a net.
The important viewing points are conspicuously vivid appearance of the meshes and light blue, spotless head region. However, as they age, black spots often appear in the head region and Hi on the belly tend to climb up reaching as far as the back.
