Axolotls are part of the Ambystoma family, meaning that they are very closely related to animals such as the Tiger Salamander and are true amphibians. The name Axolotl comes from the aztec language and has many translations thought to mean water dog or water slave.
A few different colour variations exist in captivity including the wild type colour which can be olive green to dark brown or grey, black, gold and albino colour variations also exist. All axolotls stay in their larval stage for the entirety of their lives and remain fully aquatic throughout., this is called Neotony.
Axolotls can grow up to 30cm in length at maturity and in the right conditions can live up to 15 years so are a long term pet. They require a good sized aquarium of a minimum of 3 ft in length for a pair. Axolotls are messy, carnivorous eaters so therefor they need very good filtration such as an oversized external canister filter and plenty of regular water changes with dechlorinated water. They do not require heat and in fact water that is too warm, over 20 degrees c, can cause problems such as bacterial infections so cold water is fine. Tank decor can range from live plants to just rocks for hiding places. Axolotls are inquisitive and like to explore their surroundings. Axolotls will predate on fish if they can catch them, therefor we would recommend always keeping Axolotls in a separate tank and try to keep all Axolotls of the same size if housing more than one. Axolotls may squabble with one another and occasionally injuries such as lost limbs can occur. Axolotls have an amazing ability to regrow tissue such as lost limbs but care should always be taken to avoid injuries becoming infected.
Feeding axolotls is easy as they will take most meaty foods such as bloodworm, earthworms, crickets, mealworms or Hikari Massivore. Be sure to keep your axolotls well fed but also keep a regular eye on the water quality in your tank as these high protein foods can cause high nitrate and phosphate problems.
Breeding Axolotls is a little tricky. Inducing breeding is the easy bit as a good dose of really cold water usually triggers spawning. This can be achieved by undertaking a big water change with colder water that is in the tank or by dropping some bottles of frozen water in the tank overnight. Spawning will usually take place on the live plants in the tank and will look like small frogspawn. The difficult part is feeding the hatchlings. They will require feeding around 24 hrs after hatching and can be fed the same as the adults but chopped up very finely. Cannibalism is not an unusual occurrence so separating the babies may need to be separated.
Axolotls are a great beginners amphibian and make great pets for kids and adults alike. As long as these basic guide lines are followed Axolotls can live a happy and healthy life in you aquarium
