Axolotls are aquatic for life and need cool water, ideally 16–18°C and never above 22°C, with a filtered, cycled tank and gentle flow. Test for ammonia, nitrite and nitrate weekly. Use bare bottom or large smooth stones — fine gravel causes fatal impaction.
Most species need a planted vivarium with a stable temperature, correct humidity and a shallow, dechlorinated water dish. Tree frogs need height, terrestrial species need floor space and a damp substrate. Low-level UVB and calcium supplements keep bones healthy.
Captive-bred amphibians travel better, carry fewer parasites and are legal to sell without collection concerns. Never take native frogs, toads or newts from the wild — great crested newts and their habitat are protected by law.
Ask the exact species and morph, whether it is captive bred, its age, what it is feeding on and how often, and the temperature it is kept at. Skin should be clean and unbroken, eyes clear and the animal alert. Have the tank cycled and running before collection, and find a vet who treats amphibians first.
