Axolotls are aquatic salamanders that belong to the family Ambystomatidae. As aquatic animals, axolotls extract oxygen from the water through their feathery gills – which means that the oxygen concentration in their environment is important for their survival.

Axolotls have been observed blowing bubbles in a few different contexts, including while swimming, resting, and grooming.

Why is an Axolotl Blowing Bubbles?

Axolotls are known to blow bubbles as a normal behavior, and there are a few reasons why they may do so:

  • Grooming: Axolotls may blow bubbles to help clean their skin by dislodging debris and particles from their skin – which can then be carried away by the water current.
  • Oxygenation: Axolotls may generate bubbles to increase the oxygen concentration in their environment – which can be beneficial for their respiratory function.
  • Playfulness: Axolotls are known to engage in playful behaviors, and expel bubbles may be one such behavior.
  • Exploration: Blowing bubbles may be a way for axolotls to investigate their environment or to mark their territory.

Finally – Axolotls may produce bubbles as a form of play or exploration. Like many other animals, axolotls have been observed engaging in a variety of playful behaviors, and blowing bubbles may be one such behavior.

Blowing bubbles may be a way for axolotls to investigate their environment or to mark their territory.

While the exact reason why axolotls emit bubbles is not entirely clear, it is likely that the behavior serves a variety of purposes, including grooming, oxygenation, and play.


Axolotls will Blow Bubbles for various reasons – As long as the axolotl is otherwise healthy and active, forming bubbles is likely a normal and harmless behavior for Axolotls.

However – if your axolotl is blowing bubbles excessively or appears lethargic, it may be a sign of an underlying health issue and should be evaluated by a VET who specializes in exotic animals.

Do Axolotls Make Bubble Nests?

Axolotls do not make “Bubble Nests” in the same way that some other aquatic animals, such as Betta Fish, do. Bubble nests are created by male fish during the breeding season, and they are used to protect and aerate the eggs.

Axolotls are known to blow bubbles for various reasons – as mentioned in my previous answer. Sometimes axolotls may gather bubbles in a specific area, such as around a plant or a rock, and this may look like a small bubble nest.

But this is not the same as a true Bubble Nest created for breeding purposes – like Betta Fish do.

In general, if you notice your axolotl creating a collection of bubbles in its tank, it is likely just a normal behavior and nothing to be concerned about.

Do Axolotls like to play with Bubbles?

Yes, axolotls are known to enjoy playing with bubbles. Axolotls habitually expel bubbles by sucking in water and then expelling it through their feather gills – or by blowing air out of their mouths.

When Axolotls see the bubbles, they may try to chase after them or even bite after them – which can be quite entertaining to watch.

Playing with bubbles is not only fun for axolotls but can also provide them with some exercise and mental stimulation. It’s important to provide axolotls with enrichment activities like playing with bubbles, as this can help keep them healthy and happy.

Please Note:

While bubbles can be fun for axolotls – make sure that the bubbles are not causing any harm to the axolotl or their environment.

Very Strong Bubbles can cause agitation or discomfort to axolotls if they create too much water movement or noise. Monitor your axolotl’s behavior and adjust the amount and frequency of bubbles accordingly.

Should i put a Bubble Stone in an Axolotl Aquarium?

It is generally safe to put an aquarium Bubble Stone in an axolotl aquarium – but there are a few things you should consider before doing so!

Axolotl playing with Bubbles

Bubble stones can be helpful to oxygenate the water in your aquarium, which is important for the health of Axolotls. Axolotls have feathery gills that allow them to breathe underwater – having enough oxygen in the water is crucial for Axolotls survival.

A bubble stone can also help to create a gentle water flow that can keep the water circulating and prevent stagnant areas in the aquarium.

It’s important for you to choose the right type and size of a Bubble Stone and to use it carefully. Some types of bubble stones can create too much agitation in the water, which can stress out axolotls and even damage their gills!

It’s best to choose a bubble stone that creates small, gentle bubbles that don’t create too much water movement or noise.

Please Note:

Bubbles can sometimes trap debris or waste, which can create poor water conditions if not cleaned regularly.

Therefore, it’s essential to keep up with regular aquarium maintenance, including cleaning the filter and performing water changes as needed.

The Breathing System of Axolotls – Short Overview

Axolotls are very fascinating animals – one of their most unique features is their breathing system.

Unlike most other terrestrial vertebrates – Axolotls can obtain oxygen from both air and water – which allows Axolotls to survive in a variety of different natural environments.


The Anatomy of the Axolotl Respiratory System

Axolotls have a pair of lungs connected to their throat and mouth by a series of air passages.

Axolotls also have feathery gills, these gills are located on either side of the head and Axolotls use them to for breath underwater.

These gills are covered by a flap of skin called the “Operculum” – which helps Axolotls to regulate the water flow over the gills.

Breathing Underwater: How Axolotls Use Their Gills

When an axolotl is in water – the Axolotl will extract oxygen from the water through its gills.

As water flows over these gills, oxygen molecules will diffuse across the gill membranes and into the bloodstream – while carbon dioxide diffuses out of the bloodstream and back into the water.

These gill system is very efficient at extracting oxygen disolved in water, allowing axolotls to breathe even in low-oxygen environments.

Breathing on Land: How Axolotls Use Their Lungs

When an axolotl moves on land or near the water’s surface, it can also breathe air using its lungs.

The axolotl’s lungs are relatively small – compared to those of other vertebrates – but they are able to extract oxygen from the air using a process called buccal pumping.

During “Buccal Pumping”, an Axolotl closes both – its nostrils and mouth – and uses its throat muscles to pump air in and out of its lungs.

Adaptation to the Environment: How Axolotls Adjust Their Respiration

The ability to breathe air and water makes axolotls very adaptable and allows this unique Salamander to survive in a variety of different habitats.

In Axolotls natural habitat in Mexico – Axolotls live in shallow and stagnant water conditions -where oxygen concentrations can be very low.

By being able to extract oxygen from both – air and water – Axolotls can survive in environments – even when oxygen levels!

Another interesting aspect of the axolotl respiratory system is that Axolotls can adapt to changes in the environment. For example, if an axolotl is exposed to high levels of carbon dioxide, its fether gills will produce more “Bicarbonate Ions” to buffer the acidity and prevent acidosis in his body.

This adaptation helps to maintain the pH balance of the blood and keep the axolotl healthy.

Understanding Buccal Pumping: How Axolotls Breathe in Water and Air

Buccal pumping is a method of respiration used by many amphibians, including axolotls! Buccal Pumping involves the movement of air into and out of the lungs through the mouth, rather than through the nostrils as in most mammals.


During the “Buccal Pumping” process, an Axolotl will close its mouth and nostrils and use its throat muscles to pump air in and out of its lungs.

As the axolotl Breathes In: The Axolotls mouth opens and the throat muscles contract, drawing air into the lungs.

When the axolotl breathes out: The Axolotls mouth closes and the throat muscles relax, this is pushing air out of the axolotl lungs.

Buccal pumping is an effective method of respiration for amphibians because it allows them to obtain oxygen from both air and water.

Axolotls are particularly well-adapted to living in fresh-water – they are able to extract oxygen dissolved in water through their feathery gills.

Axolotls or other Amphibians do Not typically blow Bubbles during Buccal Pumping; this is because buccal pumping involves moving air directly into and out of the lungs, rather than through any other structures that might produce bubbles.


Axolotls are fascinating aquatic creatures that extract oxygen from water through their feathery gills. They are known to blow bubbles as a normal behavior, and this can serve various purposes – such as grooming, oxygenation, playfulness, and exploration.

It is generally safe to put a bubble stone in an axolotl aquarium, but it’s essentil to choose the right type and size and to monitor water quality closely.

Axolotls can use both – their lungs and gills to breathe – allowing them to adapt to different environments, and they can also use buccal pumping to breathe in water and air.

Overall, axolotls have unique respiratory systems and behaviors that make them fascinating animals to observe and learn about.
