I really like this, and think we got it as a very good price , due to the koi being very stressed.What appears to be black in the pecks, is in fact stress. The beni is very good and a superb pattern. When the light catches the skin you can see how good it really is, and at 36cm its certainly jumbo. Purchased from the Dainichi auctions , so should come with a breeders certificate. This was judged to be female on the 5th May by the breeder, but cannot be guaranteed.
