How Long Do Axolotls Live?

Axolotls typically live 10-15 years in captivity when given proper care, though some have reached 20+ years. In the wild, their lifespan tends to be shorter around 5-6 years due to predators, pollution, and habitat loss. These unique salamanders can outlive many other amphibian pets when their water quality, diet, and tank conditions meet their needs.

What Affects Their Lifespan?

Water quality matters more than anything else. Axolotls need cold water between 60-64°F (16-18°C). Warmer temperatures speed up their metabolism and shorten their lives. You’ll want a good filter, but nothing too strong they don’t like heavy currents. Weekly water changes keep ammonia and nitrites under control, which prevents stress and disease.

Diet plays a big role too. Young axolotls eat daily, while adults only need food 2-3 times per week. Overfeeding causes obesity and liver problems. Earthworms, bloodworms, and salmon pellets work well. Some owners stick to one food type their whole lives without issues.

Tank size gives them room to move. A single adult needs at least 20 gallons, though 30-40 gallons works better. They grow 9-12 inches long, so cramped spaces create stress. Stress weakens their immune system and makes them vulnerable to infections.

Common Health Problems

These creatures heal incredibly well they can regrow limbs, organs, and even parts of their brain. But they still face health challenges. Fungal infections show up as white cotton-like patches on their skin. Poor water conditions usually cause this. Bacterial infections happen when injuries don’t heal right or when water parameters swing wildly.

Temperature shock kills quickly. A sudden jump from 64°F to 72°F can be fatal. Always match water temperatures during changes. Some axolotls develop tumors as they age, especially after year 10. There’s not much you can do about genetic issues, but good care helps them live comfortably despite these problems.

Quick Questions

Do axolotls live longer than other salamanders?
Yes, most salamanders live 5-10 years, while axolotls can reach 15-20 years with excellent care.

Can axolotls live in tap water?
Only after treating it. Chlorine and chloramines in tap water burn their gills. Use a water conditioner before adding it to their tank.

How do I know if my axolotl is aging?
Older ones slow down, eat less, and sometimes develop darker spots or tumors. Their gills may shrink slightly, but this isn’t always a bad sign.

What’s the oldest recorded axolotl?
The oldest confirmed case reached 25 years, though this is rare. Most pet owners report 12-15 years as the average.

Do males or females live longer?
No clear difference exists between the sexes. Care quality matters way more than whether you have a male or female.
