They can't possibly stay under, can they!? If so, what if the pond freezes all the way down?

No, they do stay under the water. That is due to Anomolous behaviour of water
At 4 ºC, water has its highest density. It actually contracts as the temperature rises from 0 ºC to 4ºC. This means that in regions with severe winters, lakes cool at the surface, and when the surface water reaches 4 ºC, that water, being more dense, sinks. A temperature gradient is set up, and when the water freezes, it does so at the surface. Eventually, the ice, which floats on water, acts as an insulator, protecting the water below it from further cooling.
This results in lakes freezing from the top down, and not from the bottom up. This means that fishes can survive below the ice even if the air temperature is far below 0 ºC for prolonged periods. The reason for this anomalous behaviour of water is beyond the scope of the Physical Science curriculum.

The fish can live under the water when it freezes over for who knows how long, because there is so much oxygen in the water. It would have to be a pretty shallow pond to freeze all the way down.

Even at very low temperatures a pond or lake that can support fish would take an extremely high amount of energy to freeze completely. Plus when a lake or pond freezes at the surface, the ice acts as somewhat of a barrier from the colder air and prevents the water below from freezing completely. The fish stay underwater (which allows for ice fishing). They typically stay in shallow waters because that is where the remaining food in the water is.

A body of water will usually not freeze all the way through to the bottom, thereby allowing the fish to swim freely with all the food and air that they need. However, should a pond or fish tank freeze all the way through, the fish would obviously not be able to swim.
On the other hand, the constant motion of the fish could be the reason that the water doesn't freeze all the way through.

If a pond freezes solid the fish die. Otherwise if the pond is deep enough they do just fine down on the bottom. And in the lowered temperatures they need almost no oxygen and absolutely no food,even in the Spring,overfeeding is a danger. Until the pond is really warmed up the fish require almost no food at all.------PeeTee

Usually if it is a private pond or a small pond people will take the fish out and keep them in a tank inside for the winter.
Other than that I think the fish die.

i'm sorry to assert that your fish are in all hazard long gone..... some frogs and salamanders can proceed to exist the freeze. they have evolve an antifreeze chemical of their tissues.. So whilst spring comes around, they are in all hazard to stay lower back.. yet all your fish are a various case. next time, this is recommended to look at a puppy shop. there are multiple decrease priced heaters available. in the journey that your pond is deep, it is going to possibly no longer be frozen to the backside. yet it fairly is particularly no longer likely on the grounds which you observed lots of the fish iced up. in the event that they nevertheless have water, ruin the ice as quickly as a threat to maintain oxygen going into the water. I went to a cafe previously and the fish is frozen in a block of ice. They place it in an aquarium and enable it thaw. After a on a similar time as the fish replaced into alive and swam. uncertain if this will additionally take place on your fish. yet i wish it does

Once a pond gets a layer of ice on it the lower levels of water don't freeze. They virtually go into a hibernation state. Unless its a big lake or river. Then they move around. However, fish seem to be able to survive in cold cold water due to their chemical makeup in their blood.

The water only freezes over at the top; maybe halfway down, but it stays liquid at the bottom so the fish can live

The go to the bottom and become relatively sedentary. If the pond freezes to the bottom they would die. That would be a very rare situation.
