Your average fish can breathe perfectly fine, however, both in motion and at rest, so long as the water is oxygenated sufficiently
. They will not die if they stop swimming. Simply being in oxygenated water is enough for fish to breathe and survive.
Can fish control their breathing?
Like us, fish need oxygen to survive. But
to breathe, most pull oxygen-containing water into their mouths and pump it through their gill chambers before expelling it out of their gill slits
. Now, for the first time, scientists have seen fish “holding” that breath, some for up to 4 minutes at a time.
Do fish ever stop moving?
Sometimes people see fish when they're sleeping and assume they're awake because they're still moving.
Most fish need to keep moving even when they're sleeping
, so that they keep a constant flow of water moving past their gills to maintain a proper oxygen level in their bodies.
Why do fish suffocate in air?
Though some fish can breathe on land taking oxygen from air, most of the fish, when taken out of water, suffocate and die. This is because

Would a fish survive in vodka?
Oxygen-free living
This is when an organism ends up by chance with an extra set of its genes, which can then be repurposed to take on new functions.
By making alcohol, crucian carp and goldfish can survive where no other fish can
, meaning they can avoid predators or competitors.
Can a fish get drunk?

How do fish pee?

through an tiny opening, called a pore, that's near their rear ends

How do sharks sleep?
But scientists weren't sure whether most fish slept too.
Some sharks are known to go into a restful state where they stop swimming and stay in one place
, which could be done to conserve energy and hints that they sleep. But no one had explicitly measured sharks' metabolic rate during these restful periods.
Can you drown a shark by pulling it backwards?

How do fishes sleep?
While fish do not sleep in the same way that land mammals sleep,
