For someone seeking to keep an axolotl in captivity as a pet it is recommended to use a long aquarium having a minimum of 18 inches in size. A standard 20 gallon aquarium is usually large enough for one adult axolotl.

You don’t desire to fill the entire tank with water, you only need enough to pay for the axolotl and enable some room for movement. Typically most enthusiasts fill the tank up about halfway for the top in most tanks, this allows an excellent depth water for your axolotl, and enough space on top so water will not overflow from your movement in the axolotl.

Under the tank it is recommended you place black plastic of black paper, since the bottom of the aquarium, it can help the axolotl to possess a natural and darker tank bottom. Enthusiasts often use polystyrene board wrapped in a black plastic bag to aid using the color as well as spread the weight more evenly.


Filtration is not required for axolotls, provided that you’re ready to regularly change this type of water. If you decide to use a filter there are a variety of possibilities, like under-gravel, external “cling on” filters, and canister filters, all will work fine for axolotls but are not required if you want to change most of the water in the tank weekly.

Axolotls excrete lots of waste, mainly in the form of ammonia (NH3). Through the whole process of nitrification, ammonia is converted into the less harmful substance nitrite (NO2). This method is one of the most significant aspects of filtration and is also known is biological filtration.

If you are considering using a mechanical filter, we recommend “aging” your tank for at least 2 weeks after filling it with water and installing the filter, before adding any axolotls. This will assist in the progression of the bacteria on the filter media, and then in preparation for adding your axolotl.


Axolotls cannot “grip” the base of a glass tank, and can cause unneeded stress with time, so that we recommend you use a substrate such as sand or rock.

Standard aquarium gravel is not suitable for use within your axolotl tank since the small pieces can become lodged inside your axolotls gut and also you can risk injuring or killing your axolotl.

Should you do want to use gravel you must use gravel are at least pea sized, about 1/4? or larger in diameter. Alternatively you can also have fine sand since it does not cause any blockages in the axolotl.

A favorite gravel utilized in most axolotl tanks is actually a aggregate coated in polymer to avoid it from leeching any chemicals in to the water and harming the axolotl. The gravel comes this way, already coated in polymer, and is available in many sizes and shapes.


Axolotls tend not to require any special lighting, standard aquarium fluorescent lighting will work just fine for all axolotl tanks. Until you are keeping live plants, a standard “hood” style aquarium light will work great for your tank.

Axolotls do not require light to survive, the light is purely for display purposes. The sole requirement would be had you been keeping live plants inside your aquarium, which may require special lighting.

Temperature & Heating

The water within your axolotl tank ought to be kept between 57-68 degrees, which generally in most homes does not require any heating or cooling to keep in this temperature.

Temperatures below 57 degrees leads to slower metabolic process a sluggish axolotl. Temperatures above 68 degrees boost the risk for disease, and fluctuations between warm and cool temperatures between nigh and day can additionally be stressful in your axolotl.

If you do require heating for your aquarium, standard heaters found in vtqydg aquariums, both beneath the tank and then in tank, will work fine to your axolotl tank.


Adding decoration such as plastic plants, caves, and rocks provides the axolotl an additional feeling of security, and it is visually popular with the human eye.
