What Do Axolotls Need in Their Tanks?

Axolotls, also known as the "Mexican walking fish," are a unique and fascinating species of salamanders that are popular pets among aquarium enthusiasts. If you're considering keeping axolotls as pets, it's important to understand what they need in their tank to thrive. In this blog, we will explore the essential components of an axolotl tank and what you need to provide to keep your axolotls healthy and happy.

Water Quality

Axolotls are aquatic animals, and it is essential to maintain good water quality in their tank. The water in the tank should be kept at a constant temperature between 60 and 72 degrees Fahrenheit, and it should be filtered to remove debris, excess food, and harmful chemicals. Additionally, it is important to perform regular water changes to maintain good water quality and to keep the axolotls healthy.

Filtration System

A good filtration system is essential to maintain good water quality in the axolotl tank. A suitable filter should be able to handle the water volume in the tank and should be cleaned regularly. Water changes are a great way to ensure water parameters stay in great shape. Additionally, it is important to choose a filter that is appropriate for the size of the tank and the number of axolotls you are keeping.


A suitable substrate should be used on the bottom of the axolotl tank to provide a comfortable environment for the axolotls. The substrate should be smooth and not too rough, as rough substrate can damage the delicate skin of the axolotls. We recommend only using fine sand, bare bottom, or rocks that are at least 3x the size of the axolotls head to ensure they are not a choking hazard. We highly discourage the use of pebbles and other small, unsecured substrates that could cause impaction, which can be deadly for axolotls.

Decorations and Plants

Axolotls enjoy having places to hide and explore, and it is a good idea to provide decorations and plants in their tank. This can include rocks, caves, and live or artificial plants. However, it is important to choose decorations and plants that are safe for axolotls, as some plants and decorations can release harmful chemicals into the water.


Axolotls do not require special lighting, but it is important to provide enough light in their tank to allow you to observe them and to maintain good water quality. A suitable light source, such as a fluorescent bulb or LED lights, can be used to provide the necessary light.


In conclusion, axolotls need a well-maintained tank with good water quality, a suitable filtration system, an appropriate substrate, decorations and plants, and adequate lighting to thrive. By providing these essential components, you can create a healthy and comfortable environment for your axolotls and keep them happy and healthy.
