In one experiment, Chapman compared how upside-down and right-side-up catfish performed under low-oxygen conditions in a laboratory. She found that
their swimming positions allowed the upside-down fish to breathe at the surface more easily
, while the right-side-up ones had to work harder for the same benefit.
Why is my fish breathing but upside down?
Swim bladder disorder is a condition when the swim bladder isn't working properly due to various possible factors
. A swim bladder is a gas-filled internal organ that helps a bony fish maintain its buoyancy. The disorder refers to a collection of issues affecting the swim bladder, rather than a single disease.
Can fish drown if they are upside down?
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.
Why is fish upside down?
That said, the decomposition process can sometimes result in enough gas being produced and trapped inside the fish to cause it to float to the surface. So in short, fish float upside when they die
because many of them are top heavy and posses an organ in their lower region that is filled with air
.
Do fish play dead?

,” but the nuanced response sheds light on how fish, and all other organisms, function. Fish have evolved over many millions of years to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecules.
Do fishes fart?
Biologists have linked a mysterious, underwater farting sound to bubbles coming out of a herring's anus. No fish had been known to emit sound from its anus nor to be capable of producing such a high-pitched noise.
Can a fish get thirsty?

. 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.
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.
Why do dead fish float upside down?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as
bacterial decomposition produces gases inside the body
. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
How do you revive a dying fish?
Place Your Fish in Suitable Water
Take your fish in your hands and place it in cool water from the fish tank. The oxygen in the water will help the fish breath and thus, revive it. More often than not, if you place the fish back in its own fishbowl, the water will fill life back into your weakfish.

Why is my goldfish floating but still alive?
Many goldfish eat like ravenous Golden Retrievers, sucking in floating food at the surface. In doing so, they inadvertently suck in extra air, resulting in added volume to their swim bladder.
Additional air in the swim bladder results in a positively buoyant fish, aka a floaty fish
.
Why do fish act so weird?
Strange Swimming:
When fish are stressed, they often develop odd swimming patterns
. If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.
Can I flush my dead fish down the toilet?

it's a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
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 you drown a 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.
Can spiders fart?
Since the stercoral sac contains bacteria, which helps break down the spider's food, it seems likely that gas is produced during this process, and therefore
there is certainly the possibility that spiders do fart
.
How do fish pee?
A lot of fish get rid of the pee
through an tiny opening, called a pore, that's near their rear ends
—and in some fish, waste also goes out through the skin or the gills. When a fish pees in a coral reef, the corals wave their tentacles around like tiny arms to grab nutrients from the pee and absorb them.
