That really depends on how long it is staying still for. Some fish are capable of just sitting there and fanning water across their gills so that they can breathe. This means that they can sit there until they eventually starve and die.
no, they need to constantly be moving to have the water run through their gills to breathe...
fish stay in their own zone because they need to stay away from dangerous creatures and sometimes they don't want to be alone with other fish they don't know.
well they always swim and dont stay still but they will go far and sometimes come back to where they started.
Aquatic snails (as opposed to land snails) and fish live entirely in water - either fresh or salt, depending on their nature.
Guppies are fresh water fish who will die in salt water.
Perhaps its in a sort of shock? If the fish in question is a new pet fish, I mean. Normally when you buy a new fish, it comes in a plastic baggie. You're supposed to place the sealed baggy (with fish/water still inside) into its new fish tank. This makes the water in the baggy slowly change to the temperature of the water in the fish tank, and prevents the fish from undergoing the "shock" that accompanies dumping it into a different temperature environment.
A fish swims to move in the water, eat, travel, survive, live. Swimming is how fish move in the water like how animals on land walk and run.
Tropical fish stay at the bottom of the tank when the water is changed.Its because fishes feel a change in water, like the temperature and pH value, due to which they get stressed, so they decide to remain in corner or at the bottom of the tank, until they feel they are comfortable.

I don't think there are any fishes that cannot stay in water.
How long a red tailed catfish can stay out of the water depends on the fish in question and how moist the fish's gills are.

Sharks are fish as they must stay in water to breath, but amphibians when an adult can live on land and water.
The fact that ice floats means that the lake probably will not freeze solid all the way down. There will still be liquid water at the bottom of the lake where the fish can stay alive all winter.
Fish always stay and live in the water, while amphibians live on both land, and water.
