He/she is probably just developing mature coloring. Many goldfish will be
widely varied in their coloring as juveniles, but as they grow up they will
become completely orange. I bought 4 feeders of all different colors and
patterns. Every one of them is solid orange now.

Would a 2mm-wide black lining along the entire edge of my orange fantail's caudal fin and a 1mm-wide black lining along it's dorsal
fin be able to disappear in just 3 weeks as a result of maturing?
I though these color changes take quite a bit of time to develop.

My 2nd fantail (Clinton) is completely orange now and looks just like my first fantail (Carter).
