The Axolotl (Ambystoma mexicanum) is a permanently aquatic salamander from Mexico, famous for retaining juvenile features into adulthood (neoteny) and for an extraordinary regenerative capacity — they regrow lost limbs, heart tissue, and parts of the brain. The pink or "leucistic" form with feathery external gills has made the species an internet star. Critically endangered in the wild.
Native to Lake Xochimilco near Mexico City — now nearly extinct in the wild due to habitat destruction and invasive species. Captive population is robust and entirely captive-bred.
Stays in larval form lifelong (unlike most salamanders that metamorphose to terrestrial adults). Lives fully aquatic with external gills.
Adults 23–30 cm length, 200–400 g.
Colour morphs: wild (dark olive), leucistic (pink with dark eyes), albino (pink with red eyes), melanoid (solid dark), golden, copper, chimera (genetic mix).
External feathery gills, lidless eyes, long flat tail.
Aquatic observation pet only. Never handle — their skin is fragile and absorbs oils and bacteria. Lift only briefly using a soft fine-mesh net if necessary.
Minimum: 75 L (20 gallon) for one adult; 110 L (30 gallon) preferred. Larger for pairs.
Provide:
Carnivore.
Avoid: feeder fish (parasite risk), beef heart (digestion issues), live aquarium fish (some carry diseases).
Juveniles eat daily; adults every 2–3 days.
10–15 years.
Common concerns:
Salts (Holtfreter's solution) baths and tubs of cool dechlorinated water help injured or sick axolotls.
Pros:
Cons:
Not suited for tropical climates without chiller, beginner aquarium keepers, households with toddlers.
Why are they always pink? Most pet axolotls are leucistic — a colour morph with white-pink skin and dark eyes. Wild axolotls are dark olive with spots.
Do they really regrow limbs? Yes — limbs, gills, parts of the heart and brain. The species is heavily researched for regenerative medicine.
Are they salamanders? Yes — Mexican salamanders that fail to metamorphose. With thyroid hormones they can be forced to metamorphose into terrestrial adults, but the process often kills them. Don't try.
How long do they live? 10–15 years on average.
Can I keep two together? Adults can coexist; juveniles often nip each other's limbs. Best to keep adults singly or with careful supervision.

"The axolotl is an aquatic salamander that never grows up. It keeps its larval gills, fins, and aquatic lifestyle into adulthood, living entirely underwater. It is critically endangered in the wild, lives 10–15 years in captivity, and is one of the most fascinating amphibians you can keep. Today: complete axolotl care."
"Axolotls (Ambystoma mexicanum) are native to a single lake system — Xochimilco in Mexico City. Pollution and invasive species have driven the wild population to functional extinction. Captive axolotls descend from decades of laboratory and pet-trade breeding. The species is widely studied for its limb-regeneration ability. Albino, leucistic, melanoid, and wild-type colour forms exist."
"Tank minimum: 100 litres for one adult. Filtration: gentle. Strong currents stress axolotls. Substrate: bare bottom or fine sand. Never gravel — impaction risk. Temperature: 16–18°C. Above 22°C is dangerous; above 24°C is lethal over time. Cooling: aquarium chiller often needed in summer. No heater. Lighting: dim. Axolotls dislike bright light. Hides: PVC pipes, ceramic, terracotta pots."
"Carnivore. Adults: earthworms (preferred), bloodworms, axolotl pellets, frozen fish. Feeding schedule: adults 2–3 times weekly. Never: feeder fish (parasites), goldfish, dog/cat food."
"Best housed singly. Adult axolotls may coexist but juveniles nip limbs. No fish tank mates — fish nip gills. No other amphibians. Cycled tank essential before introducing axolotl."
"Lifespan 10–15 years. Fungal infections (Saprolegnia) — usually stress-related. Bacterial infections from poor water quality. Impaction from gravel substrate. Stress from warm water. Find an exotics vet experienced with amphibians."
"Mistake one: warm water. Lethal. How to avoid: aquarium chiller in summer. Mistake two: gravel substrate. Impaction. How to avoid: bare bottom or fine sand. Mistake three: fish tank mates. Nip gills. How to avoid: axolotls only."
"Checklist: 100+ litre tank. Cool temperature feasible (chiller if needed). Cycled tank. Exotics vet identified. 10-15 year commitment. Tick four — axolotls are wonderful."
