Goldfish cannot survive being completely frozen. They can survive the top of the pond being frozen if the water is sufficiently oxygenated. Basically if the water in a cell freezes...the crystals rupture cell walls...there by killing the fish.
Ok...they can survive cold...but heck they do REALLY REALLY well in warm water year round. The japanese could never grow there goldfish very large very quickly until they took them to Thailand where it is extremely warm year round.

True Goldfish are non-tropical. Meaning that they do not need a heated tank. My goldfish came from WalMart @ 10 cents each and live in my outdoor pool year round. The temperature drops well below freezing sometimes. My friend used to keep his goldfish in his horses water trough to cut down on the mosquito population and they would freeze solid but would defrost the next warming trend!

NO, they cannot survive being frozen. When living cells are frozen, they expand and rupture, killing the fish or other creature. I would guess that the horse water trough did not freeze solid or it would have broken apart as the water expanded while freezing.
Goldfish can, however, overwinter in a pond that is frozen over, but it needs to be deep enough that they can find non-frozen water at the bottom. Inside a house, they enjoy temps of 60-65 degrees (they are coldwater fish).
Never break the ice on a fish pond once it is frozen, the shock waves will damage/kill your fish.
Once the water is colder than 55 degrees you are not supposed to feed them because their metabolism slows to the point that they cannot digest food. It stays in their digestive tract and they eventually die from the obstruction.

Everyone is right, they can certainly take cold cold cold, and being frozen, although frozen fish are not as fun to look at, they don't do anything but stay there.
68 is a nice temp for them, and it will keep all the little parasites away.

haha...
they can't survey being frozen. As long as the water is not completely frozen over, they're fine. Some people leave them out in the pond over the winter.
The original gold fish came from northern china where it's plenty cold.

As long as the temperature changes slowly, they can actually survive being frozen. So, pretty cold water is just fine.

I would say pretty cold. I had a 10 gallon fish tank with gold fish (my first tank) and I never had a heater on it. They lasted 6 years, probably longer if I took better care of them. Now I have a 55 gallon saltwater tank with a heater!

mine live outside year round and during really cold winters the ice has gotten 3 inches thick (pond is 24 " deep)
