What's the Best Axolotl Tank Size?

Are you planning on getting an Axolotl? Or maybe you already have one and are unsure what tank size to get for your unique amphibian.

You need to understand their basic needs regarding tank size, water parameters, temperature, food, and more. That's why, in this article, we'll tackle everything you need to make your Axolotl right at home.

What Size Tanks Does an Axolotl Needs?

A good rule of thumb is to have at least 20 gallons for adults and 10 gallons for juveniles Axolotl. However, a regular water change is needed for juveniles to prevent any health issues.

For Axolotl, the recommended tank size is 20-30 gallon tanks. These are ideal because ammonia and nitrate levels in this size are controlled. They also give enough room for your Axolotl to explore and play around. 

The larger the tank, the better. So, it's best to have a 40-gallon tank. They prefer to spend their entire lives underwater, so a large enough tank for them to interact, play, and live in is essential.

If your tank is small, this will adversely affect their growth. It is advisable to have a 40-gallon tank, as it will allow you to keep plants and other decorations in it. 

Do leave some space to install the filtration system. 

Handling More Than 1 Axolotl

Having more than one Axolotl may cause some problems, as it can lead to aggression and behavioral issues. The best tank for two or more Axolotl is 55-75 gallons. Anything below that won't work. 

If you have other fish in the aquarium, their requirement might increase. 

It's not recommended to keep more than two Axolotl in a tank. You might need to clean the tank more frequently. Also, Axolotl are quite pets and can get easily stressed. If you have a tankmate for you, Axolotl, go with the fish species of the same size.

How to Setup Axolotl Tank

Find the Right Aquarium: We have established that tank size matters. 

Filtration: Having a filtration system is essential so that your Axolotl can live comfortably. They usually make a lot of mess when feeding. So, choosing the right filtration ensures that the water quality and condition remain in their optimal state. We recommend getting a filter with an adjustable flow rate knob to handle more than just the tank size.

Uneaten food: Apart from filtration, you may need to remove uneaten food from your tank to keep the water clean.

Substrate: Many Axolotl do not use substrate due to impaction, but if you are opting for plants and other decorations, having a bare bottom is just not the way to go. You can add rocks that don't fit in an Axolotl's mouth—something large enough that they won't be able to ingest. 

Plants: Plants are great for your Axolotl to play. But floating plants are the way to go. 

Water Chiller: An aquarium chiller is sometimes an essential part of the Axolotl tank, as the ideal water temperature is around d 16-18 degrees Celsius. They provide the right temperature, especially in hot, humid places. 

Lights: If you are not getting plants, then lights are not really necessary. If you ever opt to do that, go for a dim light that mimics their natural habitat. Don't overwhelm their sensitive eyes. It's best to get the lighting system with a dimming option. 

Tankmate: Axolotl is an introverted and solitary creature throughout their life. If you do decide to get a tankmate, do watch out for their behavior as their aggressiveness can cause them to fight other species, and they may end up losing their limbs:

Security: Though they are solitary creatures, they are quite the peaceful type. They can't really climb, but they can leap out of their tanks. Other pets and children might be a problem as they can cause harm to Axolotl.
