Some just faded and others' colour went in patches. Other goldfish in pond not affected except one Koi which started off navy blue all over (he's about 8 years old). He started losing colour round his scales on his back and now his back is totally white/silver while his lower scales are blue/black and still gradually turning white.
He's otherwise very healthy - same as the goldfish. Help!!!

Water conditions, temperature, what you feed them, age, genetics and color of background all can have an effect on color of koi. There is an excellent article in Aquarium Fish magazine this month on why koi change colors. The fish is not ill and there is likely nothing you can do but wait and see what color it turns out to be. Some will retain vivid color and many will loose color as they age. Warm water can retract color where cold water makes color expand. Ph also has a simular effect. Green water or a pond with lots of algae can make colors deeper. Hope this helps. Many experts are apparantly trying to scientifically figure out what exactly causes a koi to loose color. What I've read its a combination of things but mostly breeding or genetics of the fish.

I don't know about koi, but comets and I believe common goldfish, it's common for them to turn white. I have 3 now, one is still orange, one has turned white/silver, and the other is starting to turn white. Here's a link I have saved, click on color changes:

It sounds like it's just pigment changes from the sunlight. Mine have been doing this for the past year. Originally I had my pond in a shaded undercover area, now it's in a sunny location, and that's when the color change started. As long as they appear healthy, should be fine.

Goldfish and koi are constantly being genetically manipulated by breeders to invent ever new colors, markings and physical points of interest, thus, these fishes' genes never really get a chance to stabilize and the weaker genetic characteristics will fade and revert to a more stable one long after birth. Black/blue is the most unstable of all the colors and is the one most likely to fade. They make color-enhancing foods, which may help, but the fact remains that you can't reverse a genetic change. At best, you can only slow it down. Don't worry. While it's sad to see that beautiful blue/black fish lose it's color, this is just part of life. It's okay.

WHAT THE **** ***** that **** that reported OMG ITS SUFFICATE **** NO ITS not first threat is that the goldfish is sexually maturing with the aid of a protracted volume of time . in case you stored the goldfish for a short volume of time then it is on the grounds which you have not got the superb easy fixture or you activate and rancid the lights too lots to reason the fish rigidity. different than that there is not something it somewhat is achievable

Maybe someone scared them? Just kidding.
I would call the pet shop you bought them at and ask them. If they can't answer you, then try calling around to other pet shops. Is there a store near you that specializes in pond equipment?
