Gold fish eggs fertilized or not..?

This question has been asked before. the best Answer is still the same. it takes 2-3 days for a goldfish egg to hatch. if it is infertile, it will turn white by the start of the second day. The fertile ones do get noticeably darker, but iit is definintely an exaggeration to say you can see the embryos' eyes until a few hours before hatchng, and not always clearly even then. The colder the water, the longer the eggs will take to hatch.
