Can a fish breathe out of water?
by
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 gill arches of fish collapse, when taken out of water, leaving the blood vessels no longer exposed to oxygen in air.
Typical pond fish species, such as koi carp and goldfish, are not equipped with special mechanisms for surviving outside of water. They will quickly deteriorate within a few seconds of gill exposure to air, and will seldom survive past the 3- to 5-minute mark without access to water.
Which fish can live without water for 2 years?
But West African lungfish blow these other fish out of the water: They have gills and a primitive lung. During dry periods, the animals wrap themselves in a mucus cocoon, burrow into the mud, and lie dormant—sometimes for years.
How long can a fish last without air?
Goldfish and their wild crucian carp relatives can survive for five months without breathing oxygen – and now we know how. The fish have evolved a set of enzymes that, when oxygen levels drop, ultimately helps convert carbohydrates into alcohol that can then be released through the gills.

Do fishes Act Dead?

Why is my fish upside down but alive?
Why Is My Fish Swimming Upside Down? If your fish is swimming upside down, it has a problem with its swim bladder. Your fish has stopped being able to control its swim bladder and has got stuck with too much air inside it. The reason for this could be constipation, a poor diet, eating habits, or an infection.
Do fish float if they are dead?
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.
Why is my fish not moving but still alive?
If fish are experiencing acute stress (i.e., gasping up at the surface, lying on the bottom and not moving, or darting around the aquarium), you can be pretty sure that the water has been poisoned in some way. Maybe cleaning sprays got into the aquarium, or something released toxins into the water.

Is my fish dead or sleeping?
Moving your fish using a fish net is the best way to detect if your fish is dead or sleeping. If your fish suddenly try to get free from the net, they are sleeping; if they don’t show any movement, they are dead. Also, look for the movement of gills to detect whether they are resting.
Why did my fish just disappear?
Serial fish disappearances can be caused by a number of factors. Water conditions are a top candidate to consider, as well as disease, and even a bully who is murdering and consuming his tank mates.Another possibility is that the fish are all old.
Can a fish revive itself?
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.
Sometimes, fish like to bury themselves in the sand. Other times they manage to camouflage with the plants or hide in them if they are big enough. There are also chances that they are hiding in decorative pieces, any shell of a crustacean, or somewhere in the filter pipes near the tank.

Can fish in a tank hear you?
Yes, fish can hear you talk!
Sounds that are created above water typically do not carry enough force to penetrate the surface tension of the water, so talking on the boat or loud noise may not affect fish as much as your fellow anglers may want you to think. Your voice is unlikely to spook or scare fish away.
Can you put fish directly in the tank?
