The short answer is
Yes, they do
, Hence the reason they need to rest to regain strength. The creatures that live in the pelagic environment never stop swimming. It's the same with fish.
What fish cant stop swimming?
Manta Rays
are in Perpetual Motion
Manta rays belong to a group of fish who are in a constant “state of perpetual motion”. This simply means that mantas never stop swimming. If they did, they wouldn't be able to breathe. Manta rays need to keep moving in order to have oxygenated water passing over their gills.
Why has my fish stopped swimming?

improper water temperature
. If your fish's water is too hot or too cold, they will be very inactive. Check your heater and verify that your aquarium is at the right level. Other possible causes are overfeeding and improper water quality.

Can fish breathe without swimming?
For most cartilaginous fish, they have five or more gill slits that open directly into the water. They rely on something called “ram ventilation” to push water through their gills. These are the fish that need to swim to breathe, because the forward movement is what pushes water through their gills.
Can a fish stop moving?
Some species, such as the shark (cartilaginous fish), need to move constantly to stay alive
. What allows its buoyancy is its large fatty liver. While other fish, such as pike (bonefish), can remain motionless because they have an inflatable or swimming bladder, which keeps them afloat.
Why is my fish not moving but still alive?
The
impaired buoyancy in fish is caused by a malfunction of their swim bladder
. When affected by Swim Bladder Disorder fish will often lose the ability to properly swim. They will float uncontrollably to the top of the aquarium, turned upside down, while still being alive.
How can you tell if a fish is sad?

Is my fish dying?
Loss of appetite
. Weakness or listlessness. Loss of balance or buoyancy control, floating upside down, or ‘sitting' on the tank floor (most fish are normally only slightly negatively-buoyant and it takes little effort to maintain position in the water column) Erratic/spiral swimming or shimmying.
Do fish ever fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart
.
Do fishes cry?

fish cannot cry
because they lack the part of the brain which allows mammals to produce tears. This part of the brain is called the cerebral cortex. Besides, fish lack both the emotional depth and mental complexity to be able to cry.
Can sharks drown?
Despite being ocean dwellers, most sharks need oxygen to breathe. They don't have lungs but instead absorb oxygen from the water using their gills.
If there's not enough oxygen available in the water, sharks can't breathe and can easily drown
. This isn't the only reason sharks drown.
Can fishes feel pain?
CONCLUSION. A significant body of scientific evidence suggests that
yes, fish can feel pain

Can a fish come back to life after being out of water?
Caught early enough a fish can recover, even from a surprisingly dry state
. However, how you handle the fish immediately on discovery is crucial to its survival. The first thing to do is get the fish back into some water, but in a safe environment. Simply dropping the fish back in to the tank is a bad idea.
Do sharks stop swimming?
Myth #1: Sharks Must Swim Constantly, or They Die

. The ability to move up and down freely in the water column is, in fact, one of the extraordinary adaptations of sharks.
Does fish get thirsty?

Can you drown fish?
Yes, fish can ‘drown'
–for lack of a better word. Though, it is better to think of it as a form of suffocation where oxygen levels are too low or the fish isn't able to properly pull oxygen from the water for one reason or another.
How do fishes sleep?
While fish do not sleep in the same way that land mammals sleep,
most fish do rest
. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Do fish play dead?
Let's revisit the example of the fish playing dead.
Some species play dead to fool other fish, often targeting scavengers as a food source
. The Central American cichlid is a perfect example. In other species, though, this behavior might hint at a health issue.
Why is my fish on the bottom of the tank not moving?
Water temperature is either too low or too high
When the water temperature inside your aquarium drops too low, your fish might lay motionless at the bottom of the tank to conserve energy.
How do you revive a dying fish?
