Axolotl Care Guide (2026)
Axolotls (Ambystoma mexicanum) are one of the most unique and rewarding aquatic pets you can keep. Native to the lake complex of Xochimilco in Mexico, these permanently aquatic salamanders are beloved for their feathery gills, wide range of morphs, and surprisingly manageable care requirements — once you understand their cold-water needs.
This guide covers everything you need to keep your axolotl healthy and thriving.

- Diet: Carnivore — worms, pellets, frozen bloodworms
- Difficulty: Beginner–Intermediate
Tank Setup
Axolotls need a cool, well-filtered aquarium. A 20-gallon tank works for a single juvenile, but a 40-gallon breeder is the gold standard for an adult. They produce significant waste, so a quality canister or sponge filter is essential — just make sure the flow isn't too strong, as axolotls stress easily in high-current environments.
Skip the gravel substrate — axolotls will ingest small particles and develop impaction. Use fine sand or go bare-bottom. Hides and caves are appreciated, as axolotls like to retreat from light.
Water Temperature
This is the most critical factor in axolotl care. Axolotls are cold-water animals and will suffer — and die — in warm water. Keep temperatures between 60–68°F (16–20°C). Anything above 72°F (22°C) causes chronic stress and immune suppression. See our Axolotl Water Temperature Guide for cooling strategies.
Feeding
Axolotls are carnivores. The best staple foods are nightcrawlers (earthworms), Hikari Axolotl pellets, and frozen bloodworms as treats. Feed juveniles daily and adults every 2–3 days. Remove uneaten food promptly to keep water quality high. For a full breakdown, see our Axolotl Feeding Guide.
Axolotl Morphs
Axolotls come in a stunning variety of color morphs — from the classic wild-type to leucistic (white with pink gills), golden albino, melanoid, and the increasingly popular mosaic and chimera morphs. See our Axolotl Morphs Guide for a full breakdown.
Common Health Issues
Axolotls are hardy but susceptible to fungal infections, bacterial infections, and impaction. Most health issues trace back to poor water quality or incorrect temperature. See our Axolotl Diseases Guide for symptoms and treatments.
Not Eating?
A common concern for new owners. Usually caused by stress, incorrect water temperature, or overfeeding. See our Axolotl Not Eating guide for a full troubleshooting checklist.
Lifespan
With proper care, axolotls live 10–15 years in captivity. Learn what factors affect longevity in our Axolotl Lifespan guide.
Are Axolotls Good for Beginners?
They can be — with the right setup. The cold-water requirement is the biggest hurdle. Read our full breakdown: Are Axolotls Good for Beginners?
Tank Size
Minimum 20 gallons for one axolotl, 40 gallons preferred. See our Axolotl Tank Size guide for stocking and upgrade recommendations.
