I have one doing that (the black to orange to white thing) now. Wasn't expecting a WHITE goldfish!CometKeith said:The black ones survive better as fry because they can hide better and not be eaten by other fish. It probably has something to to with natural selection. So over time more and more goldfish are born all black. Then eventually they usually turn orange, but you never know. I had one go from black to orange to white!
