I have (or had) an orange goldfish. It is in a 10 gallon tank with one other goldfish (a red caped oranda). The orange goldfish has recently been aquiring white spots of his back. And in the last week he has turned almost completly White, the only orange on him is a faint spot on his back. I heard that this can be caused by lack of sunlight and lose of pigment. Is this True, If so what can I do to get him to turn orange again (if I can do anything that is).
