When a Fish Falls, Does It Suffer Damage? Can It Survive?

You may have heard of cats landing on their feet or humans sustaining serious injuries from falls, but what about fish? Do they take fall damage? Can a fish survive a fall?

In this post, I’ll explore the unique anatomy of fish, factors affecting their fall damage, and instances where fish may find themselves falling. We’ll also discuss how to minimize potential harm and how to assess fish health after a fall.

So the short answer to whether fish take fall damage is yes, they can. However, the severity of the damage depends on several factors, such as the height of the fall, the water surface tension, and the landing surface.

Some fish can indeed survive a fall, but again, this depends on various factors that we’ll delve into throughout the article.

Understanding Fish Anatomy

Before diving into the details of fish fall damage, let’s first understand the key aspects of fish anatomy that come into play.

a. Swim bladder

The swim bladder is an internal organ filled with gas that helps fish maintain buoyancy in water. This organ can also act as a cushion when a fish falls, reducing the impact of the fall and potentially saving the fish from fatal damage.

b. Scales and slime layer

Fish are covered in scales that provide a layer of protection, while a thin slime layer aids in reducing friction and helps protect against infection. These features may offer some level of protection during a fall.

Factors Affecting Fish Fall Damage

Now that we know the basics of fish anatomy, let’s examine the factors that determine how much damage a fish may sustain during a fall.

a. Height of the fall

As with any other creature, the height of the fall plays a significant role in the amount of damage a fish may sustain. Greater heights lead to higher impact forces, which can result in more severe injuries.

b. Water surface tension

If a fish falls into water, the surface tension of the water can act as a cushion, potentially reducing the damage. However, if the fish falls onto a hard surface, the impact can be much more severe.

c. Landing surface

As mentioned earlier, the surface on which a fish lands can greatly affect the outcome of the fall. Soft, wet surfaces, such as a wet towel or grass, can reduce the impact and increase the fish’s chances of survival.

Fish and Waterfalls

a. Natural environments

In their natural habitat, some fish may encounter waterfalls, which they must navigate either by swimming upstream or falling downstream. These fish have evolved to withstand the impact of falling from varying heights, depending on their species and specific environments.

b. Adaptations

Fish that inhabit environments with waterfalls often have unique adaptations that help them survive falls. For example, some species may have stronger bodies, more flexible skeletons, or more developed swim bladders, enabling them to better withstand the impact of a fall.

Fish Species and Fall Tolerance

Not all fish are created equal when it comes to withstanding falls. Let’s take a look at some examples of fish with varying degrees of fall tolerance.

a. Sturdy species

Some species of fish, such as catfish and carp, have robust bodies and may be more likely to survive a fall. Additionally, certain species that naturally navigate waterfalls, like salmon, are more adapted to handle falls.

b. Fragile species

On the other hand, some fish species have delicate bodies and may be more susceptible to injury during a fall. Examples of these fragile species include neon tetras, angelfish, and certain types of goldfish.

Fish Falling on Land

a. Impact on gills

When fish fall on land, their gills, which are responsible for extracting oxygen from water, can become damaged. This damage can lead to difficulty breathing and, in severe cases, death.

b. Drying out

Another risk for fish falling on land is the potential for them to dry out, as they are not adapted to survive outside of water. Prolonged exposure to air can cause severe dehydration and death in fish.

Human-Induced Fish Falls

a. Angling mishaps

In some cases, fish may experience falls due to human actions, such as mishandling during angling. When caught on a hook, fish may be accidentally dropped, leading to potential injury.

b. Aquarium accidents

For fish kept in aquariums, accidents like a fish jumping out of its tank or being dropped during maintenance can also result in falls.

Minimizing Fish Fall Damage

To reduce the risk of harm to fish during falls, several precautions can be taken.

a. Proper handling

When handling fish, it’s essential to use wet hands or gloves to minimize stress and avoid removing the protective slime layer. Additionally, it’s crucial to handle fish gently and securely to prevent accidental drops.

b. Wet landing area

If a fish must be placed on a surface, such as during angling or aquarium maintenance, it’s helpful to have a wet, soft surface available. A wet towel or grass can help cushion the impact and reduce the risk of injury.

Assessing Fish Health After a Fall

If a fish has experienced a fall, it’s important to assess its health and well-being.

a. Physical examination

Look for any visible signs of injury, such as damaged scales, bruising, or bleeding. If you notice any concerning signs, it may be necessary to consult a veterinarian or aquatic specialist.

b. Monitoring behavior

Keep an eye on the fish’s behavior in the hours and days following the fall. If the fish is showing signs of stress, difficulty swimming, or unusual behavior, it may be an indication of internal injuries or other issues.

In conclusion, fish can indeed take fall damage, and their ability to survive a fall depends on a variety of factors. Understanding fish anatomy, environmental factors, and species-specific traits can help us better appreciate the risks faced by fish in such situations. Taking precautions to minimize potential harm and closely monitoring fish after a fall can help ensure their well-being and survival.


  1. Do all fish have the same level of fall tolerance? No, different fish species have varying levels of fall tolerance, depending on their anatomy and natural environments. Sturdier species, such as catfish and carp, may be more likely to survive a fall compared to more delicate species like neon tetras or angelfish.
  2. What should I do if my fish jumps out of its aquarium? If your fish jumps out of its aquarium, quickly and gently pick it up using wet hands or a soft, wet cloth, and place it back into the tank. Monitor the fish closely for any signs of injury or distress.
  3. How can I prevent my fish from jumping out of the aquarium? To prevent fish from jumping out of the aquarium, ensure the water parameters are suitable for your fish species, provide plenty of hiding spots and cover to reduce stress, and consider using a secure lid or mesh cover on your aquarium.
  4. Is it possible for fish to survive falls in the wild? Yes, some fish species can survive falls in the wild, especially if they inhabit environments with waterfalls or rapids. These fish may have unique adaptations to help them withstand the impact of falling.
  5. How can I minimize the risk of injury when handling fish? To minimize the risk of injury when handling fish, use wet hands or gloves, handle the fish gently and securely, and prepare a soft, wet landing surface if the fish needs to be placed on a surface outside of the water.
