Its a nice pond grade Shusui.
I like the fact that the pattern is symmetrical and that the zip look mostly uniform. Unfortuanly it looks like a piece of the zip is missing.
I also like the red rings around the eyes but that is just a personal comment.
The blue one the koi is a bit too dark for me.
The blueish head should clear up with time and become whitish but it will develop sumi spots down the road.
Shusui has the same genetical problems as asagi. They get dark and very spotty down the road.
Key things to look for in a Shusui.
1. No spots anywhere.
2. A complete symmetrical zip from head to tail.
3. The zip must be a light blue colour.
4. Symmetrical hi marking on the side.
5. A white nose and face.
6. Hi in the pectoral fins.
'n goeie Shusui is soos hoender tande.
