Any fish large enough to swallow a goldfish will probably do so. Most fish eating birds will also eat them. Then of course there are the human idiots. People who swallow live goldfish because they think it is a 'smart' or 'in' thing to do.
A goldfish does not have a predator, but it can still die from lack of food or water.
Goldfish are omnivores and cannibals so other larger goldfish can be predators to your smaller goldfish. Other predators include carp and koi. Non-swimming predators can include raccoons or house cats.
Only place goldfish into an aquarium with other similar-sized goldfish. 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.

seals are Not top predator. not even sharks are top predator. i think the goldfish i top predators (=
mostly shark rarely whale
Wokori: They are both vertebrates.
Most likely not. If there are goldfish, then there are definetely going to be predators. Goldfish are small, and one predator could eat about 5 goldfish. It's very unlikely, but possible.

Well it depends. If your msle goldfish shows signs of being a predator. Remoe the fish immediately.
This would primarily be birds, but any other meat eating animal that can easily access them would be a predator (foxes, otters etc)
A goldfish does have a nose but its nares (like nostrils) are not connected to its mouth. Instead it is connected to a chamber lined with sensory pads. A goldfish can smell various chemicals in the water when that water is passed over its sensory pads. There are chemicals that are a signal for food, chemicals that signal a predator, chemicals that signal when it's breeding time or even chemicals that are given off by wounded or alarmed fish.
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.
Yes, the rate at which a goldfish grows, and its overall size, is often partially determined by its environment. This is why pond goldfish are considerably larger than aquarium goldfish, and why goldfish that are cramped-up in bowls stay relatively small. If you want your goldfish to grow into large healthy fish you'll buy them a large aquarium or pond to live in.
No you cannot put a frog with goldfish; goldfish belong with goldfish
