The axolotl, often dubbed the “Mexican walking fish,” is an intriguing amphibian celebrated for its unique appearance and neotenic nature. Unlike most salamanders, axolotls do not undergo metamorphosis, retaining their larval features, including external gills, throughout their adult lives. This aquatic creature, scientifically known as Ambystoma mexicanum, is native to Mexico and makes a fascinating pet for those who appreciate aquatic life. While they are not cuddly pets that you can handle frequently, their captivating charm and relatively simple care needs make them a popular choice for aquarium enthusiasts.
This guide provides a comprehensive overview of Mexican Axolotl Care, covering essential aspects such as habitat setup, dietary requirements, behavior, and health to ensure your axolotl thrives.

Understanding Axolotl Behavior and Temperament
Axolotls are known for their docile and non-aggressive nature. They are relatively hardy but possess delicate bodies primarily composed of cartilage and permeable skin, making them sensitive to rough handling. It’s crucial to avoid unnecessary handling; when required, use a soft, fine-mesh net to prevent injury to their limbs or delicate gills.
Once their environment is properly set up, axolotl care is relatively straightforward, requiring only a few hours per week for feeding and tank maintenance. They are often observed exploring their tanks and can become accustomed to their keepers, sometimes even approaching the glass out of curiosity.
Axolotls are solitary creatures and do not require tank mates. In fact, housing them with other species can be problematic. They may attempt to prey on smaller fish, and conversely, fish might nip at their gills. Even cohabitating axolotls requires caution. Juvenile axolotls are prone to cannibalism, necessitating separate housing during their early stages. Adult axolotls can sometimes be kept together, but close monitoring is essential to prevent nipping or cannibalistic behavior. Remarkably, axolotls possess regenerative abilities and can regrow lost limbs or gills if injured, but preventing such incidents is always preferable.

Setting Up the Ideal Axolotl Habitat
A tank size of at least 15 to 20 gallons is recommended for housing axolotls. Ensure the tank has a secure lid as axolotls are known to jump. Unlike some amphibians, axolotls are entirely aquatic, so a land area is unnecessary. The water depth should be slightly greater than the axolotl’s length, providing ample swimming space and contributing to better water quality.
Tank substrate is another consideration. Some keepers prefer bare-bottom tanks for ease of cleaning. However, others believe a substrate provides better footing and reduces stress. If using substrate, opt for coarse gravel larger than the axolotl’s head to prevent ingestion and potential impaction. Fine sand or large, smooth stones are also suitable alternatives. Avoid fine gravel or small decorative stones that can be accidentally swallowed.

Maintaining Optimal Water Conditions
Water parameters are critical for axolotl health. Keep the tank in a cool, dimly lit room, away from direct sunlight. Water temperature should be maintained between 57°F and 68°F (14°C and 20°C) and never exceed 75°F (24°C). High temperatures can cause stress and illness. Axolotls do not require special lighting; in fact, they prefer subdued lighting and appreciate hiding spots like caves, flower pots, or aquarium decorations.
Use dechlorinated tap water treated with an aquarium water conditioner to remove chlorine and chloramines. Distilled water is not suitable. The ideal water pH should be between 6.5 and 7.5. Regular water testing kits available at pet stores can help monitor pH and other water parameters.
Filtration is highly recommended to maintain water quality and reduce the frequency of water changes. However, axolotls prefer gentle currents, so choose a filter with adjustable flow or use a baffle to minimize strong currents. A sponge filter or canister filter with adjustable output works well.
Regular partial water changes are essential. For filtered tanks, a 20% weekly water change, combined with siphoning waste from the substrate, is usually sufficient. Unfiltered tanks require more frequent water changes, possibly 20% daily or every other day, to prevent waste buildup. Avoid full water changes, as drastic changes in water chemistry can stress axolotls.
The Type of Water Axolotls Need
Axolotl Feeding and Nutritional Needs
In their natural Mexican habitat, axolotls are carnivorous, feeding on insects, worms, small fish, and crustaceans. In captivity, their diet can consist of a variety of readily available foods such as brine shrimp, bloodworms, earthworms, tubifex worms, small pieces of beef heart or liver (in moderation), and commercial axolotl pellets. Frozen fish food can also be offered. Avoid feeding wild-caught worms or fish, as they may carry parasites.

Feeding frequency depends on the axolotl’s age and size. Juvenile axolotls need daily feeding, while adults typically eat two to three times per week. Consult with a veterinarian experienced in exotic pets for specific feeding recommendations. Offer food using forceps or simply drop it near the axolotl. Axolotls are often more active at night, so evening feedings may be more successful. Remove any uneaten food promptly to prevent water fouling. Vitamin and mineral supplements are generally not necessary with a varied and balanced diet.

Common Health Issues in Axolotls
Axolotls are renowned for their remarkable regenerative capabilities, capable of regrowing limbs, tails, and even more complex tissues. However, they are still susceptible to various health problems, primarily related to poor water quality and improper care.
Unsanitary tank conditions can lead to bacterial and fungal infections. Symptoms include lethargy, loss of appetite, and visible skin lesions or fungus. Ammonia and nitrite buildup from waste are toxic and can cause gill damage, respiratory issues, and neurological problems. Regular water changes and proper filtration are crucial to prevent these issues.
Ingestion of small gravel or substrate can cause gastrointestinal impactions. Affected axolotls may become sluggish, lose appetite, and become bloated. Impaction can be fatal if not treated promptly, sometimes requiring veterinary intervention.
While rare, axolotls can undergo metamorphosis, transforming into a terrestrial form. This is often triggered by stress or improper water conditions and is generally detrimental to their health, significantly shortening their lifespan. If you observe any unusual changes in your axolotl’s appearance or behavior, consult a veterinarian specializing in exotic pets immediately.
Legality of Axolotl Ownership
Before acquiring an axolotl, check local and state regulations regarding exotic pet ownership. In some regions, such as California, Maine, New Jersey, and Virginia in the United States, axolotl ownership is restricted or prohibited. New Mexico permits ownership but prohibits import from other states.
Axolotls are native to Mexico and are critically endangered in the wild due to habitat loss, pollution, and urbanization. It is crucial to obtain axolotls from reputable breeders or rescue organizations and never to collect them from the wild. The pet axolotl trade relies on captive-bred animals, often descended from specimens originally used for scientific research, contributing to conservation efforts by reducing pressure on wild populations.
Purchasing Your Axolotl
The average cost of an axolotl ranges from $30 to $80, with rarer color morphs like copper commanding higher prices. When selecting an axolotl, choose an active individual that appears alert and responsive. Healthy axolotls should have smooth skin, a plump body, and no signs of injury or swelling.
Purchase axolotls from reputable breeders, specialized pet stores, or rescue groups. Avoid purchasing from online vendors or through generic advertisements unless you can verify the seller’s reputation and obtain detailed information about the animal’s origin and health history. A reputable seller should provide documentation and be transparent about their breeding practices. Consulting with a local exotic veterinarian can also provide valuable referrals to trusted breeders or rescues.
