Axolotls are hardy salamanders that are easy to keep and care for. This makes them ideal pets for new exotic pet enthusiasts. In this section we will look at the basics of keeping Axolotls as pets.

Handling of an Axolotl

Axolotls are hardy salamanders and can adjust to slight environmental variations. They however have very delicate bodies which makes unnecessary handling not recommended.

The Axolotls have the rare ability to develop sexual maturity without undergoing metamorphosis. They have features resembling salamander larvae. Axolotls have large flat heads with lidless eyes and their limbs are underdeveloped with thin long digits. They have external gills and a large caudal fin extending from behind the head to the vent.

Most of their body is made of cartilage instead of bone. Their limbs are liable to being easily injured or broken. It is not recommended to handle them unless it is really necessary. If you have to move them, you can use a fine mesh net. Be careful that the net does not entangle any part of the Axolotls body.

Housing of an Axolotl

The Axolotl is a neotenic salamander native to Mexico being found only in Lake Xochimilco. They are amphibians that do not undergo metamorphosis into adulthood keeping their tadpole state thus spend all their lives in water. To keep an Axolotl as a pet there are several factors that you will need to consider.

Aquarium size

An adult Axolotl can grow to as big as 18 inches in size. They require an ample space to move about in the tank. An adult Axolotl typically requires at least a water tank with a capacity of between 10 and 20 gallons. The bigger the better.

The Axolotl is famous for his underwater dance. They spend most of their time underwater and thus require a water tank with a depth of at least 6 inches. Ensure the tank has a lid as Axolotls may try to jump out of the water tank.

Substrate

The Axolotl will eat anything that will fit in their mouths. They feed by sucking and may accidentally feed on particles in the substrate such as gravel. This may cause digestive problems such as impaction.

Is substrate important?

Axolotls love to walk on the surface of their enclosure. Having no substrate may make your Axolotl slide as they walk which may cause them to be distressed. Additionally, it makes Axolotls happy to dig on the substrate. It is therefore paramount to have the right substrate for your Axolotls water tank.

Keeping of an Axolotl as a petSand is a good substrate. Sand particles are small hence and can pass through the digestive system if ingested. Alternatively you can use large pebbles. It also makes it easy for you to add plants and other decorations such as caves to provide hiding spots for your Axolotl.

Water properties

1.       Water temperatures

To ensure the health and well being of your Axolotl, it is important to maintain proper water conditions. Axolotls are poikilotherms.

Low temperatures slow down their metabolism while high temperatures increase metabolism. Both may lead to stress and eventually death. Keep water temperatures between 61°F and 64°F to encourage food intake.

Keep the tank in a cool room away from direct sunlight.  Additional special lighting is not required for Axolotls.

2.       Water acidity

It is important to maintain the pH level of the water at around 6.5 – 7.5. You can adjust the pH using pH test kits such as the API pH test kit sold on amazon.

Chlorine and other additives used to treat water are toxic to Axolotls. Chlorine combines with ammonia to form chloramines which are also toxic. It is essential to use dechlorinators to treat your Axolotls’ water.

We recommend tap water treated with a good dechlorinator. Do not use distilled water.

3.       Filtration

Axolotls are adapted to still waters. Filtration may interfere with the stillness of the water. Adding plants helps block some of the currents.

We recommend a 20% change of the water once every week for water tanks with filters. If you are not using a filter you may have to change the water by 20% daily. Do not do a full water change as these may change the water chemistry drastically stressing your Axolotl.

If you wish to invest in a filter, there are several filters suitable for axolotls present in the market. We recommend sponge filters such as the hygger sponge filter or AQUANEAT bio sponge filter.

Aquarium mates

Axolotls are not social animals and do not require aquarium mates. When put together with other smaller fish pets, Axolotls may consume the fish. Bigger fish on the other hand may nib on the Axolotls’ delicate body causing a lot of damage in the process.

Do not house Axolotls together. Juvenile axolotls have been reported to be cannibalistic. House them in separate enclosures.

fish, worms and insects. They will eat anything that fits in their mouths including other small Axolotls.

As pets, Axolotls can be fed on a wide variety of readily available food (Sold in pet stores). They can be fed on the following foods;

What food can Axolotls eat

  2. Frozen or live worms such as earthworms, blood worms, wax worms or black worms
  3. Frozen meals such as shrimps prawn, tuna and lean chicken or beef can be given as treats.
  4. Breeder fish – Axolotls can be fed on breeder fish although care should be taken as these may contain internal or external parasites that could affect the Axolotl.

Generally, Axolotls require no mineral or vitamin supplementation.

How often should they be fed?

Axolotl generally eat only when necessary. That is they will eat until they are full. An adult Axolotl can eat about 2 earthworms every 3 days. Juvenile and growing Axolotls may require a meal every day.

To feed your Axolotl, drop the food near him / her. You can also hang the food in the water using a string or a round- nosed forceps near the Axolotl. You can feed them during the day but if you notice they eat in the evening feed them in the evening.

It is not uncommon to find Axolotls skipping meals especially if they are still full from a previous meal. With time, you will get to know the preferences of your Axolotl. What they like to eat, how frequent and when they like it.

Remove any uneaten food every 24 hours to keep the water clean. If unsure consult your veterinarian on what and how much to feed your Axolotl as these may vary depending on their size and age.
