How long does it take for the goldfish to get its orange color back?

Answer 1

Some varieties colour up after a few weeks and around half inch long and others take months and are a couple of inches long before they show colour. There are of course some that will never colour up.

Answer 2

Goldfish were really bred/developed to be pond fish and live outdoors in China. So Goldfish need heaps of room, lots of live food, growing plants to nibble at plus a good staple diet of goldfish flakes/pellets etc and diffused daylight all of which they should get under normal pond conditions. If you want healthy goldfish all of the afforementioned should be supplied in an aquarium situation, they also need a good power filter and regular water changes. Remember the basic rules. "1 inch of fish needs a minimum of 1 gallon of water" "Every container with living creatures in it needs a cycled filter to remove the poisons". and last but not least "Every aquarium need to have at least 50% of its water changed weekly." Goldfish commonly grow to over 10 inches so the minimum size tank for a single goldfish is about 15 gallons (nominal).

Did you try that thing where you put them in the dark for a week and they turn white? it should only take about a week or two for them to get their color back but if they dont i would try switching the food your feeding them. the lack of color could indicate a vitimin dificiency.
