goldfish losing color!!!
One of my 2 year old goldfish is turning white. It is about 6" long. It is now about 80% white. This started about 1 week ago. Is something wrong with it? It seems healthy and the other 8 fish of the same age are showing no signs of this change. Is there a dietary vitamin that it is lacking. They eat only the algae that is in the pond + some ocassional koi food.
