Identity
Asagi should show a clean blue net-like scale pattern on the back, often with red or orange on the cheeks, sides, belly, and fins. The impression is quieter than Gosanke, but it can be very refined.
Shusui relationship
Shusui is the Doitsu, or scaleless, relative of Asagi. Instead of full reticulation, Shusui often shows a line of large mirror scales along the back.
Beginner note
- Look for a clean head without too much dark staining.
- Reticulation should look even rather than muddy.
- Red should support the body line without overwhelming the blue impression.
