It's very unlikely for it to stay the color it is. Have many goldfish became orange at that size and had them changed at 3-4". It's rare for a mature goldfish retained a wild coloration unless you caught some from feral populations.It will most likely stay the color it is.
Completely agree with you. Goldfish can becomes orange at any size. I keeps buying wild colored feeder goldfish but they all turned into orange.I'll say the opposite, I've had many goldfish this color and they have all turned orange. I had one up to 5 inches before it turned.
Disagreed, they can change the colors no matter what size they are.Agreed, they are showing their true colors by that size
