I got a little 3 inch koi last winter and he had beautiful orange, red and black metallic colors. Once spring time came around, I moved him into the pond. This winter I pulled him out and put him in my 125 gallon and noticed he lost the orange and red colors and is now black and white...is this common?
sorry for the poor resolution, i'll try to get a current picture of him...
