Let’s dive in and get started on this exciting journey of creating a comfortable home for your axolotl!

Choosing the Right Tank

When setting up an axolotl tank, it is crucial to choose the right tank that provides a suitable environment for these unique amphibians. Consider the following aspects when selecting a tank for your axolotl:

Size and Shape

The size and shape of the tank are important factors to consider for the well-being of your axolotl. These aquatic creatures require ample space to swim and explore. It is recommended to provide a tank with a minimum capacity of 20 gallons for a single adult axolotl. However, if you plan to keep multiple axolotls or want to promote more natural behavior, a larger tank is highly encouraged.

Axolotls are known for their long and slender bodies, so a tank with a longer length rather than height is ideal. The length of the tank allows them to move freely and provides more swimming space. Aim for a tank that is at least 30 inches long to accommodate their unique physique.


Choosing the right material for your axolotl tank is essential for their safety and well-being. Glass and acrylic are the most commonly used materials for axolotl tanks. Both options have their advantages and considerations.

Glass tanks provide excellent visibility and are less prone to scratches compared to acrylic. They also have better insulation properties, which help maintain a stable water temperature. However, glass tanks can be heavier and more fragile, requiring careful handling.

Acrylic tanks, on the other hand, are lighter in weight and more impact-resistant than glass. They offer better insulation and are less likely to develop leaks. Acrylic tanks also provide a clearer view due to their reduced distortion. However, they are more susceptible to scratches, which may affect visibility over time.

Consider your preferences, budget, and the specific needs of your axolotl when selecting the tank material.

Lid and Cover

Axolotls are known for being great escape artists, so ensuring a secure lid and cover for your tank is vital. These amphibians can easily jump out of open tanks, leading to potential injuries or even death.

Opt for a lid that completely covers the tank and prevents any gaps where your axolotl could squeeze through. A lid with a lock or a heavy-duty clip can provide extra security. Additionally, make sure the lid allows proper ventilation to avoid a buildup of humidity inside the tank.

Regularly check the lid for any wear and tear, and replace it if necessary. It is crucial to keep the tank securely covered to protect your axolotl and ensure their safety.

By considering the size and shape, material, and lid options, you can choose the right tank for your axolotl and provide them with a comfortable and secure habitat.

Setting Up the Tank

When it comes to setting up an axolotl tank, there are several important factors to consider. From tank placement to the type of substrate and decorations you choose, each element plays a crucial role in creating a suitable and comfortable environment for your axolotl. In this step-by-step guide, we will walk you through the process of setting up your axolotl tank to ensure the well-being of your aquatic friend.

Tank Placement

Selecting the right location for your axolotl tank is essential for their overall health and happiness. It is recommended to place the tank in an area away from direct sunlight and drafts. Axolotls prefer a stable and consistent environment, so avoid placing the tank near windows or doors where temperature fluctuations are more likely to occur.

Filtration System

A reliable filtration system is vital for maintaining clean and healthy water conditions in your axolotl tank. Axolotls produce a significant amount of waste, and a good filtration system helps to remove harmful substances, toxins, and odors from the water. It is advisable to choose a filter specifically designed for aquariums, capable of handling the size and volume of your axolotl tank.

Heating and Lighting

Axolotls are cold-blooded creatures and require a specific temperature range to thrive. A submersible aquarium heater with a thermostat is necessary to maintain a consistent water temperature between 60°F and 68°F (15°C and 20°C). Additionally, providing appropriate lighting is crucial for the overall well-being of your axolotl. Consider using a low-intensity light source to simulate their natural habitat while also offering them a sense of day and night.

Substrate and Decorations

The choice of substrate and decorations in your axolotl tank can greatly impact their overall comfort and safety. Opt for a fine-grained, soft substrate like sand or fine gravel, as rough or sharp materials can harm their delicate skin. Avoid using small pebbles or rocks that could be accidentally ingested by your axolotl. Additionally, provide hiding spots and aquatic plants to create a more natural and stimulating environment for your axolotl.

By carefully following these steps to set up your axolotl tank, you are on your way to providing a suitable and comfortable habitat for your aquatic companion. Remember, a well-maintained tank not only ensures the health and happiness of your axolotl but also enhances the visual appeal of your living space.

Water Parameters and Maintenance

Water Temperature

Maintaining the appropriate water temperature is crucial for the health and well-being of your axolotl. These unique amphibians are native to cool, freshwater environments, so it’s important to replicate those conditions in their tank.

Ideally, the water temperature should be kept between 60-68°F (15-20°C). Axolotls are sensitive to extreme temperature changes, so it’s essential to use a reliable aquarium heater to maintain a consistent temperature. Investing in a good quality, adjustable heater with a built-in thermostat will ensure that the water remains within the recommended range.

Water Quality

Maintaining excellent water quality is essential for the overall health of your axolotl. Poor water quality can lead to stress, illness, and even death. Here are some key factors to consider when it comes to water quality:

  1. pH Level: Axolotls prefer slightly alkaline water with a pH range of 6.5-8.0. Regularly test the pH level using a reliable aquarium test kit and make necessary adjustments to keep it within the recommended range.

  2. Ammonia and Nitrite Levels: These toxic compounds can quickly accumulate in the tank and harm your axolotl. Use a water test kit to monitor ammonia and nitrite levels regularly. Ensure that ammonia levels stay at 0 ppm, and nitrite levels remain below 0.25 ppm. If levels rise, perform immediate water changes and check the filtration system.

  3. Nitrate Levels: While nitrate is less harmful than ammonia and nitrite, elevated levels can still be detrimental to your axolotl’s health. Aim to keep nitrate levels below 20 ppm by performing regular water changes and maintaining an efficient filtration system.

Water Change and Cleaning

Regular water changes are crucial to maintain optimal water quality for your axolotl. Here are some guidelines to follow when performing water changes:

  1. Frequency: Aim to change approximately 25% of the tank water every 1-2 weeks. However, if ammonia or nitrite levels rise, more frequent water changes may be necessary.

  2. Procedure: Use a siphon or aquarium vacuum to remove debris, uneaten food, and waste from the substrate during water changes. Be gentle to avoid disturbing your axolotl. Replace the removed water with dechlorinated tap water or properly aged water to maintain the desired temperature and water quality.

  3. Filter Maintenance: Regularly clean and maintain the aquarium filter according to the manufacturer’s instructions. This will ensure that the filtration system effectively removes harmful substances and keeps the water clean.

By following these guidelines for water temperature, water quality, and water change procedures, you can create a healthy and thriving environment for your axolotl. Remember to monitor the water parameters regularly and make adjustments as needed to provide the best possible care for your aquatic companion.

In conclusion, setting up an axolotl tank requires careful planning and consideration to provide these unique creatures with a suitable habitat. By following the step-by-step guide outlined in this article, you can ensure that your axolotl has a comfortable and safe environment to thrive in. From selecting the right tank size and materials, to establishing the ideal water conditions and providing proper filtration, every aspect of the setup has been covered. Remember to monitor the tank regularly and make adjustments as needed to maintain optimal conditions for your axolotl’s health and well-being. With the right setup, you can create a beautiful and functional tank that will allow your axolotl to live a long and happy life.
