Yes they turn different colors too!
goldfish are not always one color because they have different species. Also, goldfish can change colors over time. They won't always be gold or maybe they won't always be white or whatever color your goldfish is.
Goldfish see in color.
Goldfish don't always stay the same color. As a goldfish ages, it can turn a variety of colors, like orange or yellow or white, including patches or spots of color as well.Common household goldfish tend to change colors throughout their lives. White, orange, and yellow color changes, in whole or in part, are very common.
They have a variety of colors. From orange, white, black.

We have had 2 hatchings of goldfish and they usually start changing to gold, or any other colors that they will be, at a month old, and will continue to change color while they grow.
I would guess 367
This could be multiple factors from age, to lighting changes, through to dietary changes.
