5About amphibian pets
Amphibian pets — axolotls and dart frogs — are uniquely fragile yet long-lived companions. Axolotls (Mexican walking fish) live 10-15 years in captivity with cool, clean water and low handling. Dart frogs live 8-15 years in well-planted vivariums with high humidity. Both species absorb water and chemicals through their skin, making water and substrate quality critical for longevity. Tracking age in human-equivalent years guides feeding amounts, breeding decisions, and senior care.

Common care tips for amphibians
- Maintain pristine water (axolotls) or high humidity 80-100% (dart frogs) — chlorine and ammonia kill amphibians fast.
- Keep axolotls cool (16-18°C) — heat above 22°C causes fatal stress; never heat their tank.
- Avoid handling whenever possible — amphibian skin is permeable; oils, soap, and lotion residue absorb directly into their bloodstream.
- Feed live or live-frozen prey appropriate to size; dart frogs need dust-coated fruit flies for calcium and vitamin A.
- Find an exotic vet (ARAV) for annual checkups; watch for fungal infection, gill curl (axolotls), or weight loss.
FAQ
How long do pet amphibians live?
Axolotls 10-15 years (record 20+), dart frogs 8-15 years depending on species. Both significantly outlive their wild counterparts when given proper care.
Why are axolotls so sensitive to temperature?
Axolotls evolved in cool 14-18°C lakes. Above 22°C, they suffer heat stress, immune suppression, and fungal infection. A chiller or cold-room setup is essential in warm climates.
Can I handle my dart frog?
Avoid handling. Their skin absorbs oils, soap, and chemicals from your hands directly into the bloodstream. Captive-bred dart frogs are not toxic, but handling still stresses them.
When is an amphibian a senior?
Past 60% of expected lifespan: axolotls at 8-10 years, dart frogs at 6-8 years. Senior amphibians need cleaner water and smaller, more frequent meals.
Do amphibians need a vet?
Yes — find an ARAV-certified exotic vet. Annual exams catch fungal infection, parasites, and nutritional deficiency early. Don't wait for visible symptoms.
