Crested Gecko Care husbandry priorities
Core husbandry standards
| Care area | Baseline standard | Why it matters |
|---|---|---|
| Enclosure security | Escape-proof with size planned for adulthood | Stress drops when hiding and climbing options fit the species |
| Heat gradient | Warm + cool zones measured with reliable thermometers | Digestion and immune function depend on range, not one hotspot |
| Lighting | Species-correct UVB placement and replacement timing | Bone health and normal behavior depend on correct output |
| Feeding | Whole routine with hydration + supplements | Diet issues usually show up slowly, then suddenly |
| Cleaning | Spot clean daily, deeper schedule weekly / monthly | Stable habitat reduces parasite and bacterial load |
Daily reptile care rhythm
Care guide checklist
| Measure basking and cool-side temps with real instruments | |
| Replace UVB bulbs on schedule, not just when they still glow | |
| Provide hides, hydration, and species-correct substrate | |
| Use one generic care setup for every reptile species | |
| Rely on pet-store guesswork instead of measured temps | |
| Treat appetite or shedding problems without checking husbandry |
Crested Gecko Care topics almost always come back to the same foundation: enclosure fit, measurable heat, lighting matched to the species, and calm daily observation. When those basics drift, feeding, shedding, and behavior usually drift too.
If a reptile stops eating, sheds badly, hides constantly, or shows mouth / eye / breathing changes, treat the environment check and vet triage as one workflow. Husbandry errors and medical problems often overlap instead of occurring separately.
Crested geckos (Correlophus ciliatus) are one of the best reptile choices for beginners: they tolerate room temperature (68-78F) without supplemental heating in most homes, eat a commercially available complete diet (Pangea or Repashy fruit mix), live 15-20 years, and are hardy, slow-moving, and rarely bite. They are arboreal and need a vertical terrarium with live or artificial plants for climbing and hiding.
| Parameter | Requirement |
|---|---|
| Temperature | 68–78°F — no supplemental heat needed in most homes |
| Enclosure | Vertical 12x12x18 in minimum; 18x18x24 preferred |
| Diet | Complete Crested Gecko Diet (Pangea or Repashy) |
| Lifespan | 15–20 years |
For most of the 20th century, crested geckos were thought to be extinct. Then in 1994, a cyclone hit New Caledonia and scientists who arrived to assess the damage found them thriving in the highland forests. Within a decade, they were the most popular gecko in the hobby. The reason isn't just their looks (though the eyelash-like crests and varied color morphs are genuinely striking) -- it's that they're one of the most forgiving reptiles in existence, requiring conditions that most homes already provide.
Temperature: Room Temp Is Usually Perfect
Crested geckos come from the highland forests of New Caledonia, where temperatures rarely exceed 80F. They thrive at 72-78F daytime, dropping to 65-72F at night -- a range that most U.S. homes naturally maintain. Temperatures above 85F cause heat stress and can be fatal within hours -- this is one of the few ways to quickly kill a crested gecko. In summer, monitor ambient temperatures carefully; a cooling fan directed at the enclosure (not into it) helps in warm climates. No UVB lighting is required, though low-level UVB (5.0) may support calcium metabolism and natural behavior.
A small digital thermometer/hygrometer placed inside the enclosure tracks conditions accurately. Stick-on thermometers on the glass read the glass temperature, not the air -- they're inadequate for monitoring reptile environments.
The Enclosure: Tall, Planted, and Misted
Crested geckos are arboreal -- they spend most of their time above the ground, perching and climbing among plants and branches. An 18 x 18 x 24-inch tall terrarium is the minimum for an adult; the 18 x 18 x 36-inch enclosure gives more climbing space and is worth the modest additional cost. Screen tops allow ventilation. Screen-sided enclosures (front-opening) offer easier access and better airflow than all-glass tanks.
Live plants -- pothos, bromeliads, ficus, tradescantia -- create the humidity gradients cresties need and provide natural hides. Cork bark tubes and flat cork rounds provide excellent arboreal hides. Mist the enclosure once or twice daily to raise humidity to 60-80% briefly, then allow it to drop to 40-50% before the next misting; this mimics the wet-then-drying cycle of their natural environment. Standing water in substrate causes respiratory infections -- adequate drainage is essential.
Pangea Diet Changed Crested Gecko Keeping
Before commercially prepared fruit mix diets, crested geckos were fed live insects and manually mixed fruit smoothies. Pangea Fruit Mix Complete and Repashy Crested Gecko MRP are powder-based diets mixed with water to produce a fruit-smoothie consistency that supplies complete nutrition. Offer fresh food every 2-3 days; remove uneaten food after 24 hours. Supplement with live dubia roaches or crickets dusted with calcium powder 1-2 times per week -- the hunting stimulation and protein variety support health even when the base diet is complete.
Calcium with vitamin D3 supplementation twice weekly is important for animals with no UVB lighting. Multivitamin supplement once weekly. Metabolic bone disease (MBD) from calcium deficiency causes progressive skeletal weakness and deformity in young crested geckos -- early signs include a flexible jaw, limb tremors, or difficulty gripping.
Handling and Behavioral Notes
Crested geckos drop their tails (autotomy) when threatened -- unlike most lizards, crested geckos do not regenerate their tails. The stub heals and the gecko lives normally without it, but many keepers prefer to minimize handling stress to avoid this. Handle adults low to the ground; they jump unexpectedly and can injure themselves from a fall. Young geckos (under 3-4 months) should not be handled more than briefly -- they're fragile and easily stressed at this stage.
The Merck Veterinary Manual notes Correlophus ciliatus was considered extinct until rediscovered in 1994 during a scientific expedition following Tropical Cyclone Kina. The species is now one of the most commonly kept geckos globally. Lifespan in captivity is estimated at 15-20 years with appropriate care, based on colony records at breeding facilities.
Published reptile husbandry references (de Vosjoli et al., The Crested Gecko Manual) establish the temperature sensitivity threshold above 85F as a significant welfare concern. Pangea and Repashy have published nutritional analyses of their commercial diets showing complete amino acid, vitamin, and mineral profiles meeting known gecko nutritional requirements. The AVMA exotic companion animal guidelines recommend calcium supplementation for any reptile without appropriate UVB exposure.
