How Long Do Crested Geckos Live? Lifespan Guide [2026]

Published March 27, 2026 · By ExoPetHub Team

Crested gecko lifespan averages 15-20 years in captivity. Learn what affects longevity, common health issues like MBD and floppy tail, and how to maximize their life.

How Long Do Crested Geckos Live?

Crested geckos typically live 15 to 20 years in captivity with proper care. Since the species was only rediscovered in 1994 and became widely available in the early 2000s, the true maximum captive lifespan is still being established — some individuals are approaching 30 years.

This makes a crested gecko a long-term commitment comparable to a dog or cat.

Lifespan Overview

Environment	Expected Lifespan
Wild (New Caledonia)	Unknown — likely 10-15 years
Captivity (average care)	10-15 years
Captivity (excellent care)	15-20+ years
Oldest documented	~28-30 years

Because crested geckos were only recently established in captivity, lifespan data continues to grow as the first generation of captive-bred individuals ages.

Factors That Affect Lifespan

1. Temperature

Crested geckos are extremely temperature-sensitive. They are a cool-climate species.

Ideal range: 72-78°F (22-26°C)
Maximum safe temperature: 82°F (28°C) for short periods
Sustained heat above 85°F can be fatal
Room temperature in most homes is perfect — no additional heating needed unless it drops below 65°F

2. Diet

Proper nutrition prevents the most common health issues.

Feed a high-quality commercial crested gecko diet (Pangea, Repashy) as the staple
Supplement with live insects (crickets, dubia roaches) 1-2 times per week
Ensure adequate calcium and D3 through diet and supplementation
Fresh water via misting and a water dish

3. Humidity

Mist twice daily — morning and evening
Humidity should spike to 70-80% after misting and drop to 50-60% between
Stagnant high humidity without dry-out periods causes respiratory infections and skin issues
Good ventilation is essential

4. Stress

Provide plenty of foliage, branches, and hides for climbing and hiding
Do not house males together — fighting causes serious injury and chronic stress
Keep the enclosure in a low-traffic area
Handle regularly but moderately (3-4 times per week)

5. Breeding

Breeding females continuously for many years shortens lifespan
Egg production depletes calcium and energy reserves
Give breeding females rest periods of at least 3-4 months per year
Non-breeding females tend to live longer

6. Genetics

Buy from reputable breeders with healthy lineages
Avoid extremely inbred lines
Most morph traits do not affect health or lifespan

Common Crested Gecko Health Issues

Health Issue	Symptoms	Cause	Prevention / Treatment
Metabolic bone disease (MBD)	Rubbery jaw, kinked spine, wobbly gait, lethargy	Calcium / D3 deficiency	Proper diet with calcium supplementation, low-level UVB optional
Floppy tail syndrome	Tail hangs over the back when resting on glass	Sleeping upside down on glass, weak tail muscles	Provide more horizontal perches; cosmetic issue, not life-threatening
Stuck shed	Retained skin on toes, tail tip, or crest	Low humidity, dehydration	Proper misting schedule, moist paper towel soak
Respiratory infection	Open-mouth breathing, mucus, wheezing	Stagnant high humidity, poor ventilation, bacterial infection	Improve ventilation, vet-prescribed antibiotics
Tail drop	Tail autotomy (voluntary shedding)	Stress, rough handling, fighting	Gentle handling, house separately, tail does not regrow
Egg binding (females)	Swollen abdomen, lethargy, straining	Inadequate nesting site, calcium deficiency, dehydration	Provide lay box, ensure proper calcium levels, vet if needed

Crested Gecko Life Stages

Stage	Age	Characteristics
Hatchling	0-2 months	1-2 grams, very jumpy, feed CGD daily
Juvenile	2-8 months	3-15 grams, growing steadily, becoming calmer
Sub-adult	8-18 months	15-35 grams, approaching adult size
Adult	18+ months	35-55+ grams, full size, ready to breed (if desired)
Senior	15+ years	May slow down, eat less, rest more

Tips for Maximizing Lifespan

Keep temperatures below 80°F — heat is the biggest environmental risk
Feed a quality CGD as the primary diet — Pangea and Repashy are proven formulas
Mist properly — humidity cycles (high after misting, dry-out between) prevent respiratory issues
Ensure good ventilation — screen-top enclosures or front-ventilated terrariums
Supplement calcium — prevents MBD, the most common nutritional disorder
Do not over-breed females — give rest periods to preserve health
Handle gently — never grab the tail; avoid stressing the gecko
Annual vet checkups — catch problems early with a reptile-experienced vet

Conclusion

Crested geckos are long-lived pets that can share your life for 15-20+ years. Their care is relatively simple — room temperature, quality commercial diet, proper humidity cycling, and gentle handling. By avoiding heat stress, providing adequate calcium, and maintaining good ventilation, you set your crested gecko up for a long and healthy life. As more captive-bred individuals reach advanced ages, we may find that well-cared-for crested geckos regularly exceed 20 years.

Frequently Asked Questions

What is the oldest crested gecko on record?▾

Crested geckos were thought extinct until rediscovered in 1994, so captive history is relatively short. The oldest documented individuals are approaching 30 years old. As captive husbandry improves, maximum lifespan records will likely continue to increase.

Do crested geckos live longer with or without a tail?▾

Tail loss does not significantly affect lifespan. Tailless crested geckos live just as long as those with tails. The main difference is cosmetic, though the tail does serve as a minor fat storage reserve.

Can crested geckos die from heat?▾

Yes. Crested geckos are very sensitive to high temperatures. Sustained temperatures above 82-85°F can cause heat stress and death. They thrive at 72-78°F. Keep them in a cool room and never expose them to direct sunlight.

How do I know if my crested gecko is healthy?▾

A healthy crested gecko has bright, alert eyes, a straight spine, plump body, smooth skin, a good appetite, and is active in the evening. Watch for weight loss, lethargy, sunken eyes, wobbly walking, or kinked spine — these indicate health problems.
