Yes, goldfish and koi can be bred but their offspring will be sterile, meaning they will not be able to reproduce.

I guess the mule has some similarities to this. The reason why most mules are sterile is because of a chromosome mismatch from the parents (a horse has 64 chromosomes and a donkey has 62, so the mule only has 63 chromosomes). It could be something similar that occurs with the offspring of a goldfish and koi, though i'm not certain. Genetic mutations are often random and hard to predict.

Koi and goldfish can breed producing a hybrid. The only ones I have seen were wild orange koi crossed with wild dark goldfish resulting in fish closely resembling goldfish.
