Whether in your house, the lake, or the ocean, you’ve probably seen a fish jump out of the water or tank. Not all fishes can stay airborne for a millisecond to two.

However, there are certain fishes that have the capabilities of doing so and can last longer in the air. A fish doesn’t just jump out of the water because it wants to; instead, there are reasons behind these actions.

There are several reasons why a fish jumps out of the water. It can be catching their food, avoiding predators, obstacles, and more.

Tank fish often find a way to escape because of low oxygen levels, dirty water, incorrect temperature, overcrowding, and getting rid of parasites.

Although “having fun” is not included in this list, a fish will try to get out of the water to survive. Let’s dive in to this list of reasons why fish jump out of water!

1. To avoid predators

Out in the wild, no fish is safe from predators. Whether small or big, every fish is looking to survive every day. One of the reasons why a fish may jump out of the water is because it’s trying to avoid being eaten by a predator.

When a fish jumps, the fish and the predator don’t know where it will land. Additionally, the added splash when the fish lands back on the water brings an added surprise to the predator.

Because of their primitive response, a fish first forms a C-shape (its head almost touching its tail) to flick itself out of the water. Once they get back on the water, they pad their fins as quickly as possible to try and swim away.

2. Something Spook Them

A fish may also jump if it gets spooked. Imagine cruising in still waters when you suddenly hear a roaring boat coming towards you.

Under the water, a fish can get easily spooked and jump out of the water as a reaction. This creates a ripple effect which surprises all the fishes around the area, making every fish jump around.

Even if this is an extraordinary sight, this event can become dangerous. There are instances where a lot of heavy fish will instantly leap into the air and can hit boat riders. In some cases, a fish that can weigh pounds can hit a human and cause injuries and even death.

3. To Avoid Obstacles

Most rivers have rocky areas that stop fish from going where they want. There are certain phenomena where hundreds or thousands of fish relocate to another area either to reproduce or get food during their hunting season.

To go to their spawning or hunting grounds, fish must travel for miles and avoid delays. This means they have to jump into the air if there are huge rocks in the area.

Waterfalls are also considered an obstacle to fish because of their strong current and splash. A fish must battle with the water while making their way to their respective grounds.

4. To Catch Food

Another reason a fish will jump out of the water is that they are trying to catch their food. Most fish eat insects that are too close to the water.

Some fish also eat leeches, nightcrawlers, mealworms, and more. Big fish can eat snakes, rats, frogs, and even turtles.

5. To Try And Go to A Better Location

Toxic smells and contaminated water can cause a fish to try and look for a better location. However, a fish won’t know if they are going to a better place. A mangrove killfish is an excellent example because they tend to escape toxic water in their area.

6. To Move Around While on Land

The last reason why a fish will jump out of the water in the wild is that they have to move around while on land. Although a fish knows how to wiggle around to move, jumping around makes it more comfortable and efficient.

They can get around faster when jumping and avoid injuries along the way.

7. To Get Rid of Parasites

The last reason why a fish will jump out of the water is that they try to get rid of external parasites. The higher they jump, the harder they fall, allowing them to eliminate the parasites attached to their bodies.

Why a Fish Might Jump Out of an Aquarium or Enclosure

A jumping fish doesn’t only happen in the wild, but it also happens inside a tank. When a fish tries to jump out of your tank, it can signify something is wrong in its environment. Here are four reasons a fish may want to jump out of its tank.

1. Dirty Water

Just like in the wild, a fish has a natural instinct to try to get away from dirty and contaminated water. You must regularly check and replace your water in a fish tank to ensure your fish live in a safe environment.

2. Insufficient Oxygen

A fish will continuously jump around if your tank has insufficient oxygen. Ensure the equipment you use to provide oxygen inside your aquarium has a suitable capacity. You can also plant aquarium plants to ensure enough oxygen for your fish.

3. Overcrowding

Another reason a fish will jump out of a tank is that it may be overcrowded. There’s an aquarium requirement if you have a certain number of fish in your tank. Make sure that you have the right aquarium size to accommodate your fish.

4. Incorrect Water Temperature

It’s essential in an aquarium to have the right set of water temperatures. If the temperature is too high or too low, the fish may want to get out of the water. Get your tank a mercury thermometer to ensure that your aquarium has the right temperature.

Conclusion

There are many reasons why a fish would want to jump out of the water. Whether inside an aquarium or in nature, they do this to ensure a safe environment, get away from predators, or get their food.

Have you ever seen a fish jump out of the water when fishing? It’s no wonder that it’s an amazing event to watch but have you ever wondered why do fish jump out of the water?

There are varied reasons behind the fish leaping out of the water. They do it when they have an inadequate amount of dissolved oxygen. Also, they perform this chore to escape predators, remove parasites or find potential mates.

Alongside these factors, there are a couple more reasons why they leap out of the water, and in this article, we will discover some of the significant causes. So, if you are curious about this phenomenon, keep reading.

Some Significant Reasons Why Fish Jump Out Of The Water:

Fishes leap out of the water for many reasons, and below, we have described the most significant causes behind their jumping. So, let’s read.

01. To Fool Predators:

Fish jump out of the water to dodge predators. When the chase begins between fishes and predators, fishes start heading vigorously deep inside the water and sometimes leap out of the water.

The nature of this chase isn’t like the cats and mouse chase, where cats are always after mice. On the contrary, predatory fishes make a sudden attack and catch their prey. And their attack’s timing can be anywhere between day and night.

02. To Collect Food:

Any species requires food to survive, and fish are no exception. Some fishes eat food remaining above the water or fly in the air. One such fish is the bass that catches dragonflies, and crickets in the air.

Another exciting fact regarding this fish jump is that some fishes can leap out of the water and reach a greater distance to catch various insects.

For instance, the silver Arowana can catch prey perching on tree branches or leaves. And some fishes like the monkey fish can catch even flying birds and bats just by jumping out of the water.

03. To Get Rid Of Parasites:

Some fishes get out of the water to get rid of parasites. Fishes can’t clean their bodies using their mouth or other organs like other species.

Hence, they leap out of the water to remove any pesky critters or parasites from their skins; you can say it is sort of their last attempt to get rid of those irritating parasites.

04. To Breathe:

Sometimes the levels of oxygen inside water decrease due to water pollution. Thus, some fishes can’t breathe dissolved oxygen. So, they leap out of water in search of oxygen.

One such fish is the African catfish, which gets out of the water to breathe and survive.

05. To Mate:

During procreation time, some fishes like the coho, sockeye, etc., conduct a long swim and swim through challenging-to-pass waterfalls.

While swimming, they sometimes leap out of the water, probably showing their mates strength, speed, and stamina. In this way, they lure their mates for copulation and produce offspring.

06. To Hang Around:

Some fishes gather in one place and swim together in a group. You can spot such fishes in Mexico’s gulf. This area is a nursery for certain fishes. They gather here, and both male and female fishes start swimming in the same direction.

And while swimming, they get out of the water for no reason. However, some scientists believe that these fishes leap out of the water either out of excitement or lure the potential mate.

07. To Pass Obstacles:

Sometimes, fishes leap out of the water to pass obstacles. While swimming, they face floating objects like buoys, bottles, or other things.

Hence, these fishes jump out of the river and pass floating materials to keep their swimming smooth. Some fish like salmon tend to leap out of the water to pass natural obstacles.

08. In Search Of Better Place:

When the water gets contaminated, fish try to escape and swim vigorously toward various destinations in search of a better place.

And during their journey, sometimes they get out of the water to leave toxic, smelly water behind while hoping they might land in a suitable and comfortable place.

The same reason applies to your aquarium fish. They also jump out of the tank to escape toxic water.

However, if you wanna know more reasons why your fishes leap out of the tank, you may read the next section of this article.

Some Causes Why Aquarium Fishes Jump Out Of Tanks

Aquarium fishes are known for their tendency to jump out of tanks. This can be a nuisance and cause damage to your aquarium.

Anyway, below, we have shared the most common reasons why your aquarium fish jump out of the water and have described how you can prevent them from leaping out of the tanks. Let’s read.

01. They Are Scared:

One common reason why aquarium fishes jump out of tanks is that they don’t feel safe in their surroundings.

If there aren’t enough hiding places, your fish may feel like it’s in danger and try to escape. Hence, you can add more plants and decorations to make your aquarium more secure for fish.

02. No Companions:

Another reason why aquarium fishes may jump out of tanks is that they are trying to mate.

If there aren’t any other fish around for your aquarium fish to interact with, it may become frustrated and try to jump out of the tank in search of a mate. To prevent this from happening, you can try adding another fish or two to the tank.

03. Contaminated Water:

If your tank water contains toxic elements like ammonia, nitrates, and nitrites, your tank fish will have problems with breathing oxygen. Thus, it might jump out of the tank to survive.

Hence, to help it out, you can restrain these toxic substances from building up. And to do that, you should accomplish the tank maintenance tasks regularly.

That said, you can utilize an aquarium vacuum cleaner to clean those substances. You can also use a biological filter to break down ammonia and filter out all the other harmful chemicals from the tank water.

04. The Fluctuations Of Water Temperature:

Fishes are sensitive to water temperature. And when the water temperature rises too high or low, your tank fishes can jump out of the water.

You can avert this water-temperature issue by setting up a water heater next to the filtration system. Furthermore, you can insert an aquarium thermometer to monitor the temperature.

When you notice the temperature is too low, you can switch on the heater and replace the tank water when you notice the temperature is too high.

05. Fish Jam:

Some tank fishes don’t prefer staying in crowded places. So, they tend to jump out of the water due to aggression.

However, you can solve this issue just by reducing the size of the fish stock in your tank. You can use two or more aquariums for placing a whopping amount of fish.

06. Pesky Critters Or Parasites:

The last reason your tank fish comes out of the water is due to parasites or other critters. When your tank water is polluted, your fish need to deal with several problems like skin parasites.

When the tank fish gets infested, it leaps out of the water to get rid of the parasites and damage.

Hence, you need to examine fish carefully, and if you find an infection caused by parasites, you should take the essential steps to keep the tank environment safe and healthy.

So, these are all causes why fish leap out of the water. Let us now answer some frequently asked questions on fish jumping.
