The most important need for fish live in water. Fish require water to remain alive. This is because, like all living creatures, they require oxygen to remain alive. Moreover, they’re designed to obtain this by drinking water.
How Long Can a Fish Stay out of Water? Despite how dependent fish are on the water, certain fish are in a position to remain away from it for a certain amount of time. According to the type that fish is caught, some endure for only one second, while others remain in the water for a long time or even for months.

The sole reason they don’t stay on land and absorb oxygen in the air, like you and us, is because they do not have lungs. They have gills that help to convert and absorb the oxygen dissolved in the water.
However, many fish species, each with its unique anatomy and characteristics, permit some species to absorb oxygen through the air and be in water and swim.
Each experienced fish keeper and aquarist is aware that certain fish are mammals. They have lungs and other physical attributes that aid them to obtain the oxygen they need to remain alive and store it for a period when they swim in the ocean.
How Do Fish Breathe in the Water?
It’s easier to comprehend why fish cannot survive outside of the water if you know how they adapt to water.
Fish depend on oxygen for their ability to breathe, the same way humans do. If you’ve ever had an aquarium, you likely have a system that aerated the water to your fish. The purpose of the machine was to provide your water with oxygen to allow the fish to breathe.
Fish have a distinct respiratory system to us humans. The fish’s gills are used to process the water they breathe. There are blood vessels that are tiny just beneath the gills’ surface. They function by removing oxygen in the water and releasing toxic waste.
Gills come with a structure that functions in a similar way to the lungs we breathe in. The main distinction is that they absorb oxygen from the atmosphere instead of separating the various gasses in the air and keeping the oxygen in, as the lung does.

When you pull an animal out of the water, you’ll notice its gills expanding, then collapsing frequently. This is because they’re trying to breathe. Although they are in the air, oxygen isn’t working for them.
Breathing on land can be the place where distinctions are between different kinds of species. Certain fish’s gills and respiratory systems collapse in minutes. Others may live for several days. They can live this long due to their way to absorb oxygen through their skin and keeping it in their bodies until they are back in the water.
The most important thing for most fish is whether their gills are damp. They could at most remain able to absorb oxygen, even when their gills remain still moist. If an animal leaps out of an aquarium and land on an absorbent material, the body will begin to die quicker.
How long will a fish survive in the water?
It’s vital to know that the probability of fish surviving in waters is determined by the environment that they’re in when in the water. For instance, if a fish leaps from an aquarium and falls on a surface that isn’t absorbent with a portion of the water, it will be able to survive by breathing in the oxygen content of the water so long as it’s gills are damp.
Below are a few kinds of fish that be the longest-lasting and longest-lasting when removed from the water.
Factor That Affects the Duration of Fish Survival Out of Water
1) Species
Amphibious fish, based on the species and the variety, can survive for days, hours or even decades out of water due to the body mechanisms they’ve created to endure extreme environmental conditions found in nature. Pet dishes aren’t equipped with this capability, and they can only survive for a few seconds or minutes, making it crucial to life and death to get in the water as quickly as they can.
2) Metabolic Rates
It’s known as the consumption of oxygen in fishes. It also provides information on how much energy that a fish requires to live. The metabolic rate of fish is dependent on environmental conditions, such as temperature. This also impacts the body temperature. Fish who thrive in colder temperatures are slower in their metabolic rate and live off the land for long periods.
3) Oxygen Demand
Apart from those who live in colder climates and have lower metabolic rates, They also have lower demands for oxygen and are more resistant to stress in the absence of water.
Pet Fish
Pet fish, such as rainbowfish and goldfish, are more fragile than saltwater fish. Plus, they have smaller bodies as well as smaller gills. They are prone to suffocate and even die quickly without water (following about three to four minutes without Gill movement). Therefore, it is crucial not to leave them in the water until the water they drink is suitable for them to transfer.
How long is it possible to keep fish from the in the water?
A fish kept off the water to keep it out of the water may not be the best approach to care for your fish live aquarium or pet. This is because it’s an awful experience to be without oxygen for a long period. But, if for any reason you need to do this, or it occurs accidentally, it is important to know how long your fish will last in the water.
Your goldfish pet may, in error, leap out of its bowl and lie on the ground for some time, however, gasping.
To determine the length of time, you can keep your fish from the water, keep in mind the kind of fish you own along with the reason to keep it.
Furthermore, the fish undergo the estivation process if they must be in a dry area for a prolonged duration. It is accomplished by having them are wrapped in the natural cocoon, then dug into the mud. They remain in a state of dormancy for a considerable duration, which can be for up to a year.
It is typically done in the dry seasons as the water gets dehydrated in the wild, and fish don’t have the needed oxygen. A fish that is removed from the water gets tired and may require adaptation through another method, hence the process of estivation.
How Long Can a Fish Survive Out of Water?
Let’s break it down into a few categories for the sake of accuracy.
Goldfish (and other fish species that are pet)
The length of time your fish will live outside the water will depend on whether they’re saltwater or freshwater fish. Freshwater fish are generally more fragile than saltwater ones. This is due to weak gills and smaller bodies. It’s rapid death without the water. They usually last up to 10 minutes. If they are in a panic and cannot calm themselves, the time could be less than one minute.
Saltwater fish can usually last longer but usually not long enough to last more than 10 minutes. However, occasionally they can live for up to 20 minutes if they are on non-absorbent substances.
Large Ocean Fish
Do you remember the fish species that be able to breathe on top of the ocean? These are Blue whales with short beaks, beluga whales, sperm whales, and other large marine creatures. In reality, they are, in fact, mammals that are frequently confused with fish as they are marine mammals.
Mammals, as a species, possess lung-like organs and can hold their breath for extended periods underwater. They can also remain on land for long periods; however, they will eventually need to return to the ocean to help support their bodies, or their weight could crush organs. Fortunately, this permits the whales, dolphins and certain species of pinnipeds to perform for us in the water and on the land.
Amphibious fish
Amphibious fish stand out in comparison to other species of fish. They can be out of the water for long periods. They may spend the majority of their life on land rather than in the water.
One of them is the Atlantic Mudskipper (Periophthalmus barbarus). They have adaptations that let them breathe oxygen via a specially designed lining inside their throats. Additionally, they have functional gills they use when underwater. They spend the majority of their lives outside of the water with these adaptations.
Mangrove Killifish
Mangrove killifish, also known as mangrove rivulus, is amphibious. They could live for up to one month without drinking water. According to research, they absorb oxygen through their skins when they’re not in the water. They also can keep them in their bodies. They’ll return with their guts once they return to the water.
Eels
Eels are ray-finned, elongated fish that are often seen floating on sand and rocks. They can leap over obstacles as they swim downstream like dams and have developed breathing holes in their skin. They reside in the shallow oceans and can burrow into mud, sand and hide in rocks too.
Aquarium plant divider
On average, fish last for about 10 minutes out of the water, but they can be killed faster if they land on an absorbing surface. However, saltwater fish typically live longer and certain species of fish, such as amphibious fish, have special adaptations that allow them to remain out of water.
Rockskipper Fish
Also called the coral blenny, they are freshwater fish that thrive in highly energetic environments with exposed habitats. They are famous for leaping or skipping between one pool of rock to the next in search of partners and new habitats, they can be on the ground for a long time. They are often located in shallow waters, hiding in rocks or simply jumping over rubble and breakwaters.
Climbing Perch
Fish that are native to Asian countries, specifically China as well as India. Much like those of the lungfish kind of fish comes with lungs and gills. They are an invasive species that can flourish and infiltrate other areas by simply tucking away on fishing boats to travel to another location. It is believed that they have started to flourish outside of their native habitats, including Papua New Guinea and even Australia. They can live on land for 6 to 10 hours. It travels from one location to the next by moving its body inwards. This allows it to be resilient in tough environments.
Mudskippers
Mudskippers can also be small amphibious fish that live on the land for the duration all their life. They have skin composed of blood vessels that are close to the surface. They can absorb oxygen into their bloodstream without breathing through the lungs or gills.
Snakehead Fish
The species is widespread in certain regions in Africa as well as Asia. They are amphibious and have an elongated body. They are also called predators, They also consume a carnivorous diet that feeds on plankton to smaller fishes and even rats.
Certain varieties of snakeheads can stay on the land for six days, while some can stay for months, searching for new habitats.
For those who fish with this type of fish, it’s important to be cautious when handling this kind of fish and take it out for a long period because it could slither away and snare unwitting prey.
Walking Catfish
This particular species of fish has an additional organ that assists their gills in taking in oxygen from the air that we breathe. They can “walk” or wiggle on land by flexing their muscles and using their pectoral fins as propellants themselves. You could be able to spot them on roads after large rainstorms.
Lungfish
Rare and unique species with six species left and can be found only within South America, Australia, and Africa. According to their namesake, the lungfishes reside in freshwaters like rivers and lakes. They are considered the descendants of the old Osteichthyes and are the only fish species to retain breathing oxygen on land. Lungs and lobbed fins, as well as a complete internal skeleton that is inherited from Sarcopterygii. Lungfishes rely on both lungs and gills as their habitats tend to become dry, and they enter the stage of aestivation. It is an aestivation stage in which they only use their lungs and last up to four years.
Why Do Fish Leave the Water?
For reasons of survival, unique fishes may remain out of the waters for the following reasons:
A) to avoid predators;
B) to avoid polluted waters and if the present environment is low in oxygen levels.
C) to avoid the water that is beginning to warm;
D) looking for food, mates and the biome of today is drying out or changing.
The time of life will be dependent on the species.
There are also kinds of species that can remain in the water for longer than other species. The main point is that the length of time will vary based upon the specific species. Some are dead in minutes or seconds (pet fish), while others may remain in the water for a long time (amphibious species). One thing is for sure whether you’re fishing or just changing the water in your goldfish, do not let it be stricken for a long time by lack of water.
Fishes That Can Breathe Out of Water
They are unique fish that can live and thrive on land for long periods. They are more resilient than their cousins, They might not be considered pets that are kept in aquariums, but they’re certainly captivating creatures.
In Summary
On average, fish last for about 10 minutes out of the water, but they can be killed faster if they land on an absorbing surface. But saltwater fish generally live longer, and certain species of fish, such as amphibious fish, have specific adaptations that let them remain for longer out of water.
There are numerous kinds of fish. Marine animals are not restricted to living all the time underwater. They use a variety of strategies to live in the wild, including the search for habitat, mating and looking for food. The majority of the information we have about fishes lives underwater. We, as fishkeepers, need to maintain it this way and not strain the abilities of our fish companions. Certain fish are amphibious, while certain species require air. However, since they’re all living underwater, all fish requires oxygen for their survival.
