Both koi are nice, both got nice body shape.
The Purachina looks very shinny (metallic) from the photo, which is something i personally like about it.
The Doitsu Sanke, the hi is very deep and the white on the body is snow white; the sumi i can't see clearly, but looks like the sumi will still take some time to develope.
But i am just wondering how will the Doitsu Sanke's hi develope, her/his hi is so deep (red) now. Is it going to fade or turn out to be even deeper red???
