Why do goldfish off spring end up Black & some White?

Question

I have a large black fish now & a large White one now plus some black babys????

Answer 1

All goldfish go through at least one color change throughout life. More commonly, they undergo several as they grow older (and they can be very long lived). As babies, they are all grey and grow into the more familiar gold colors as juveniles.

Answer 2

Almost all baby goldfish are born black, white or silver. They gain their color from a few months to a year.
