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.

∙ 15y agoIf fish stay still in the water for extended periods of time, they may become an easier target for predators, as movement can help them evade capture. Additionally, staying still can also make it difficult for fish to access food resources or maintain proper oxygen intake through their gills, which can affect their overall health and survival.

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.
Fish are able to stay afloat due to their swim bladders, which are gas-filled organs that help regulate their buoyancy. By adjusting the amount of gas in their swim bladders, fish can control their position in the water column. The overall shape and composition of a fish's body also contribute to their ability to stay afloat and move through the water efficiently.
Clownfish primarily absorb water through their skin and gills to stay hydrated. They are marine animals and do not drink water like land animals do.
When you change the water in your tank, the sudden change in water chemistry or temperature can stress the fish, causing them to seek refuge at the bottom where they feel safer. It's common for fish to exhibit this behavior during and after water changes until they acclimate to the new conditions.

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.
