I have a koi pond containing about 16 koi and also have 9 goldfish. Thre are also 7 "babies". I am assuming that they are goldfish babies because they have no barbels. They are about 11 months old, 1-1/5" long and black. I know a bit about koi but my knowledge of goldfish is zilch!

Are these babies likely to turn gold and if so at what sort of age/size?

Any ideas anyone?
