The simple answer is
yes, they can
. The reason they can is because the water is flowing in the opposite direction and the fish will not be able to absorb the needed oxygen. Their gills can’t gain access this way as easily.
Can a fish stay upside down?
But in the vast majority of cases, says Love, “
there’s no selective advantage for most fishes to be upside down
.” The answer, as Wainwright says, is likely that for most fish, switching simply isn’t worth it. At this point, being upright is hardwired. Simply put, fish “may not like to be upside down,” Flammang says.
Is it possible for a fish to drown?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate.
They don’t technically drown, because they don’t inhale the water, but they do die from a lack of oxygen
. Fishing equipment, such as some types of hooks, can damage the gills.
Can Sharks drown from being upside down?

a female orca was seen holding the shark upside down to induce tonic immobility. It kept the shark still for fifteen minutes, causing it to suffocate to death.
Why is my fish upside down on the bottom of the tank?
Causes of
Swim Bladder Disorder
Rapidly eating, overeating, constipation, or gulping air may occur with floating foods to cause an extended belly and displace the swim bladder. Eating freeze-dried or dry flake food that expands when it becomes wet can also lead to an enlarged stomach or intestinal tract.
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
.
Can a fish survive in milk?

Can fishes feel pain?

What keeps a fish upright?
Bony fish have an organ in their body that helps them stay buoyant and upright in the water
. The organ is filled with gas and is called a swim bladder, glass bladder, or air bladder. A healthy fish without any disease affecting the swim bladder can inflate and deflate the organ to keep an appropriate level of buoyancy.
Do fish play dead?
Let’s revisit the example of the fish playing dead.

Why does my fish sleep upside down?
Fish with disease of the swim bladder
—the organ that helps them keep buoyant—will often float sideways or upside down and have problems swimming. Lying on the side also may be an indication of a bacterial infection or high concentrations of nitrite or ammonia in the water.
Do sharks fart?
We’ve all seen tiger sharks in aquariums just hanging there, unlike most sharks which would sink, well this is their secret!
They let air out in the form of a fart when they want to lose buoyancy.
Why do Stingrays fall asleep when upside down?
Causes of
Tonic Immobility
When they’re upside down, their dorsal fins become straighter and more streamlined. The atypical stance is believed to have an effect on reciprocity with their surroundings, both through their motor and sensory reactions. Some believe tonic immobility might be a defense mechanism for sharks.
What are sharks afraid of?
Do fish always float when they are dead?
Well,
most fish will eventually float when dead
, but they will first sink as their bodies are heavier than water. The remains will only start rising once the body has decomposed enough and become buoyant.
Why is my fish swimming sideways and upside down?
Positive buoyancy disorder, where the fish floats at the surface or on its side, is the most commonly presented form of swim bladder disease, especially in goldfish. Most likely, the cause is
overinflation of the swim bladder
.
Can a fish swim bladder heal?
Depending on the cause, swim bladder disorders may be temporary or permanent.

.
What does a fish look like when it’s dying?

. Marine fish are what’s called hypertonic to the seawater. So essentially, they lose water through their gills to the seawater. The seawater is saltier than their blood.
Can a fish live in alcohol?
Oxygen-free living
By making alcohol, crucian carp and goldfish can survive where no other fish can
, meaning they can avoid predators or competitors.

Can fish See our air?
Air has an extremely low refraction index, making it impossible to see.
