About six years ago, I bought two gin rin shiro mujis (!!) who were sold to me as platinum ogons. :sigh:
One of these is pictured above, but the second one started developing yellow scales a couple of years ago.
I believe we are looking at kanoko. yes?
Not saying GOOD kanoko, but i believe it is still developing.
The last pic has been used as an example of the kanoko pattern, but is not my koi.
