Hi Nancy,
This is something I bought from Jirosuke while I was pulling some Kigoi out of a tank. I have never seen anything like it before either but it has the same quality of yellow as the other Kigoi I bought.
Since I was standing next to the breeder, or in this case the grower of the Koi, I though I would ask him. He told me that it was a Gin Rin Doitsu Kigoi. Morfe specifically than that it is called a "Koyo". I don't know if that is the correct spelling but a "Koyo" is a Doitsu Kigoi with a pattern. This one just happens to have Gin Rin on it scales so itg is a Gin Rin Doitsu Kigoi.
I sold this to Brad at the San Diego Koi Show. Brad, you have a Gin Rin Doitsu Kigoi with a pattern. Don't let anyone tell you differently.
It might just be easier to call it a "Koyo".
