What are the Tank Requirements for Axolotl? What Size Tank is Best for Axolotls? How to Perform Axolotl Tank Setup?
Axolotls grow up to an average size of 9 to 12 inches. They may not seem that large but they do generate a lot of waste. That is why the tank you select needs to be long and spacious with adequate floor space.
Here are the general tank requirements for your axolotl:
Size of tank – how big should an axolotl tank be?
For housing one axolotl, select a tank that is at least 15 gallon to 20 gallons in size – a larger tank is recommended if you plan to house several axolotls.
The thing to remember here is that this is a solitary creature and does not need company. However, you can house two axolotls together in a tank measuring about 20-40 gallons – larger the better. In fact, 55 gallons is ideal tank size for two axolotls. As long as they don’t attack each other, it means that they are ‘tolerating’ each other just fine.
The size of the tank must ensure a proper depth along with adequate floor space. Ensure a tight lid over the tank to prevent the creatures from jumping out. You can add substrate to the bottom of the but do avoid gravel.
Remember not to overfill the tank with water – leave at least 2-3inches of space from the upper rim of the tank to the surface of the water.
Filter and chiller
The tank you select should accommodate a water filter and chiller. Look for a filter that can easily filter all the water based on your tank’s size – and should also be powerful enough if you plan to add plants in your tank. Make sure the filter is noise-free.
Axolotls don’t really need too much lighting since they are sensitive to light and have no eyelids. You could add some dim LED lights if needed.
Since the axolotl hails from the wet regions of Lake Xochimilco, they need a temperature between 60 and 65 F. Many people mistakenly think that this tropical fish needs warm water. However, temperature above 75F could be harmful for your delicate pet. In fact, this is a cold water species. That is why you need fans or chillers to cool the water in summers.
Easy to clean
Axolotl tanks need frequent water changes. So make sure you select one that is easy to clean. Look for a tank with a lid to prevent your pet from jumping out.
The lid or hatch should be removable so you can easily clean the tank and make water changes without hassles.
Durable and sturdy glass
In case you opt for larger tanks (40-50 gallons), you will be adding plenty of water. So the glass of the tank should be able to withstand the pressure of water with ease. Look for tanks with glass measuring 5mm or 1/4th inch thick so it will not develop cracks and leaks.
Easy to setup
Sometimes, it makes sense in getting the entire axolotl tank kit. This can make the axolotl tank setup easier for you. Many kits come with lights, heaters, filters, chillers, and plants so you can make your pet feel at home right away.
The tank you select should be quick to set up with clear instructions.
FAQs on Axolotl Tanks
How to cool your Axolotl tank?
The key to cooling your axolotl tank water is to do it very slowly. You could add a couple of ice cubes in the water but the best thing to do is gently pour little cold water a bit by bit. Make sure you do not suddenly lower the water temperature by more than 3 degrees in a period of 1-2 hours.
There are tank chillers and fans available to keep the water temperature cool. You can also place the tank in a room with air conditioning.
What is minimum axolotl tank size?
The minimum axolotl tank size is between 10 and 20 gallon (about 50 L). For two axolotls, the tank can be larger (about 50-55 gallons) with adequate room and floor space for each one to swim without interference.
Can an axolotl live in a 5 gallon tank?
Yes, since axolotls grow to about 9 inches in size, they can live in a 5 gallon tank. However, this is not recommended since the species needs plenty of room to swim. A bigger tank is also easier to keep cool in hot summer months.
Axolotls are cute pets to keep and the ideal tank size for a single axolotl is about 10-20 gallons. For housing two axolotls, go in for a larger tank – at least 55 gallons. Add in plants and decoration and make sure to monitor the water temperature. This is a cold water species that needs water temperature between 60 and 64 F.
We recommend the Aqueon tank from OCEANIC SYSTEMS Inc. which measures 30.25 x 12.5 x 12.75 (or 20 gallons). It is sturdy, robust, and economical, and can easily house one axolotl comfortably. Do check out our other recommendations as well.
