Is goldfish scared of human

I don't know if goldfish (or any species of fish) actually feals fear as we do (as in anticipation) but they certainly do have an immediate response to any kind of threat. They hide and know how to take cover from above attack from birds etc they also know when and how to hide in plants, branches, holes etc when being hunted by predatory fish too. So to answer your question. I would say goldfish are afraid of attack both from the air and in the water by any kind of predator that would like to eat them.
