The first week
The numbers a new owner needs in the first week, each from the article it links to. Rows with no link come from the encyclopedia.
- Day one
- A new gecko is quarantined 3 to 6 months away from any reptile you already keep, on paper towel, with its own tools and a vet workup inside that window.Quarantine guide →
- Enclosure
- 18x18x24 inches is the minimum for one adult, and taller is genuinely better, a 2x2x2 foot enclosure is a common upgrade. Height matters more than floor space here.Setup guide →
- Temperature
- Ambient 72 to 78°F. 85°F is a hard ceiling with zero exceptions, this species runs into heat danger faster than cold.Setup guide →
- Humidity
- 60 to 80% overnight, spiking to 80% or higher right after the evening mist and drying to 45 to 50% by late afternoon before the next one. The daily swing is the point, not a constant number.Humidity guide →
- UVB
- Not strictly required, since a complete diet powder already supplies vitamin D3, but low-level UVB is still worth adding: a 12-inch T5 HO around 5.0, for a UVI of 0.6 to 1.4.Setup guide →
- Floor
- Paper towel for hatchlings and quarantine setups. Coconut fiber, sphagnum, or a bioactive mix for adults, at least 2 inches deep.Setup guide →
- Feeding schedule
- Hatchlings and juveniles get commercial crested gecko diet (CGD) daily, with live insects 1 to 2 times a week. Adults move to CGD every 2 to 3 days, with insects about once a week.Feeding guide →
- Not eating
- A healthy, good-weight adult can typically go 2 to 3 weeks without eating, but a vet consult is worth considering after the second week, especially with visible weight loss.Feeding guide →
- Handling
- Wait about two weeks, and until the gecko is a sub-adult of 10 to 15 grams (roughly 4 to 5 inches, about 6 months old). Then 5 minute sessions building to 15 minutes, under 20 minutes total a day. Never grab the tail, it does not grow back.Handling guide →
- Budget
- $50 to $200 for a normal morph, upward of $1,000 for rare and specialty morphs. $890 to $1,800 of equipment, $420 to $800 with the first vet exam. $40 to $55 a month after that.Cost guide →
- Adult size
- 7 to 9 inches including tail.
- Lifespan
- 15 to 20 years in captivity, with the earliest known captive individuals living into their 30s.Cost guide →
- Hygiene
- Wash hands with soap right after any contact, keep the gecko out of the kitchen, and never clean the enclosure in a kitchen sink or a bathtub people use.Hygiene guide →
- Power outage
- 65 to 72°F is the normal night low. Sustained below 72°F, day or night, causes lethargy and appetite loss, add heat, move the animal, or call the sitter.Emergency plan →
Emergency card
Call the vet now if you see any of these.
- A soft or misshapen jaw
- No bowel movement for a week or more
- Breathing difficulty
- Ongoing weight loss
- Any neurological symptoms
An exotic vet, found before you need one. Bring a new gecko in within the first 30 days of ownership, then an annual wellness exam with a fecal test as a baseline, not just when something looks wrong.

Crested Gecko Enclosure Setup: Vertical Space, Humidity, and a Hard Temperature Ceiling
The 18x18x24 vertical minimum, the 85°F hard ceiling, and why this species needs you to avoid heat rather than provide it.
Why Humidity Is Everything for Crested Geckos
The 60 to 80% daily swing, a misting schedule that actually works, and the signs humidity is running too low or too high.
Crested Gecko Feeding: Schedule, Diet, and Why They Stop Eating
Why powdered diet, not live insects, should be the staple, portion size by age, and the honest range of reasons a gecko stops eating.
How to Handle a Crested Gecko (And Why Tail Loss Is Different Here)
Settling-in time, the treadmilling technique, and why tail loss here is permanent, not regrowable.
Common Crested Gecko Health Issues and What Causes Them
Metabolic bone disease, floppy tail syndrome, impaction, stuck shed, and when a soft jaw or missed bowel movement means the vet.

Full Crested Gecko gear listFrequently Asked Questions
How long can a crested gecko go without eating?
About 2 to 3 weeks for a healthy adult at a good weight, though a vet consult is worth considering once the second week passes, especially alongside visible weight loss. Juveniles hold far less reserve and don't get that grace period. Water runs on a shorter clock: roughly 3 days.
Does a crested gecko's tail grow back if it drops?
No, and this is the critical difference from species like leopard geckos. A crested gecko's tail does not grow back once dropped. The good news is a tailless gecko, often called a "frog butt" by keepers, lives a completely normal, healthy life.
What's the maximum safe temperature for a crested gecko enclosure?
85°F, a hard ceiling with zero exceptions. New Caledonia, where they come from, tops out at 79-85°F in the hot season, and a long stretch above that risks fatal heat stroke. Too much heat is the bigger danger with this species.

Fun Facts
🦎 Rediscovered in 1994
Crested geckos were thought to be extinct for many years until they were rediscovered in 1994 in New Caledonia! These little lizards had been living quietly all along in the canopies of the islands' rainforests.
🦎 Gecko Toe Magic
Geckos can walk on walls thanks to millions of tiny hair-like structures on their toes called setae. Each foot has about 500,000 of them, using molecular forces to stick to surfaces!
🦎 Climbing the Walls
Geckos have millions of microscopic hairs on their feet that allow them to stick to even molecularly smooth surfaces! This amazing ability comes from van der Waals forces, making them one of nature's great climbers.
