When I bought my first Koi I didn't know what it was, it was about 3", metallic looking and yellow, after several years in an indoor stock tank without any light it grew and became platinum.
So I'm thinking, okay platinum Ogon, but then shortly after moving outdoors in the pond the yellow started coming back so I'm thinking Yamabuki Ogon. But now I'm spotting dark areas on the scales, almost a grey color and mostly on the middle back, is it possible that it could turn into a Ki Matsuba? Or is it just a poor quality Yamabuki Ogon?
