Golden fish
Goldfish are actually brown when they're born, and develop their adult color later.
Some goldfish foods bring out color in gold fish more than others.
Goldfish pond or an aquarium that gets some sunlight will be more brightly colored than goldfish kept in darker condition.
You should get a test kit to check your water quality.
Some goldfish change color as they age, simply because goldfish can live a very long life and that’s what their genes program them to do.
