Goldfish are omnivores and cannibals so other larger goldfish can be predators to your smaller goldfish. Other predators are carp and koi. None swimming predators can include raccoons or house cats.
Only place goldfish into an aquarium with other similar sized goldfish. By having a deep enough and wide enough outdoor goldfish pond with a few aquatic plants living in it for your goldfish to hide in, will help them avoid becoming prey to those predators.
That all depends upon the size of the goldfish. In most cases the rule is 'if is small enough to fit in a predators mouth then that will eventually happen' It is common for people to feed goldfish to their Oscars.

It is possible that a goldfish would nibble at Hornwort if it is available in its environment but I would not expect it to be a major part of a goldfishes diet.
There is no such thing as a "vampire goldfish". Except in dreams.well no one or no thing can eat a vampire gold fish because, they will bite it
Green peas are rich in fiber which is good for goldfish. The only thing is, with canned peas, I would be sure to rinse them thoroughly in water. The goldfish do not need the preservatives and salt that might be included in the canning process,
try your fish on different types of foods
Goldfish CAN eat garden snails if you break their shell open first.
