Crested geckos are arboreal animals from New Caledonia. They climb, jump, hide, forage, and choose among different temperatures, humidity levels, and resting places. Good care gives them meaningful choices within a safe environment.
The essentials
- Commitment: commonly 15–20 years or longer
- Housing: one gecko per enclosure
- Adult enclosure: tall, well ventilated, and at least 45 × 45 × 90 cm (18 × 18 × 36 in); larger is welcome
- Daytime gradient: approximately 21–24°C (70–75°F) through the cooler areas, with a controlled warm zone around 28°C (82°F)
- Night: approximately 18–22°C (65–72°F)
- Humidity: rise to roughly 60–80% after misting, then allow the enclosure to dry toward 40–50%
- Light: a consistent day/night cycle with low-level UVB and access to shade
- Diet: a reputable complete crested gecko diet, with appropriately sized live insects offered as enrichment and nutritional variety
Sustained temperatures around 29°C (85°F) or higher can cause dangerous heat stress. Any heat source must be controlled by a thermostat and checked with a reliable digital thermometer.
Housing through each life stage
Young geckos begin in secure bins suited to their size, with paper towel substrate. The simple floor makes eating, waste, hydration, and general health easier to monitor. Small does not mean empty: juveniles still need dense cover, climbing structure, hides, ventilation, and room to move.
As the gecko grows and is eating consistently, it can transition into a planted bioactive enclosure. Adults live fully bioactive. A bioactive system should include safe soil, leaf litter, live plants, cork or branches, and an established cleanup crew.
Bioactive does not mean maintenance-free. Waste, mould, plants, drainage, substrate condition, and cleanup-crew populations still need attention. Tiny ecosystem; tiny bureaucracy.
Build a usable canopy
Aim for dense cover across much of the enclosure. Provide:
- horizontal and diagonal branches at several heights
- cork, vines, and sturdy plants
- shaded sleeping places
- open routes for jumping and climbing
- an elevated feeding ledge
- a shallow dish of fresh water
An enclosure can look beautifully planted and still be functionally empty. The gecko needs pathways, resting surfaces, cover, and choices.
Humidity and hydration
Mist in the evening to create a temporary humidity rise and droplets for drinking. Allow ventilation and daytime drying between misting cycles. Constantly wet conditions encourage bacteria, mould, respiratory problems, and poor skin health.
Measure humidity with a digital hygrometer. Keep fresh water available even if the gecko usually drinks droplets.
Lighting and heat
Use a regular daylight schedule. Low-level linear UVB supports natural behaviour and vitamin D synthesis. Provide foliage and hides so the gecko can choose shade.
Create a vertical temperature gradient: warmer near the top and cooler below. Measure both areas. Avoid coloured night bulbs; darkness matters too.
Feeding
Use a nutritionally complete commercial crested gecko diet as the staple. Prepare it according to the manufacturer’s directions and place it on an elevated ledge.
- Juveniles: offer fresh prepared diet daily; offer suitable live insects once or twice weekly
- Adults: offer prepared diet every two to three days; offer suitable live insects about weekly if accepted
Remove old food, use clean dishes, and gut-load live insects. Insects should be smaller than the space between the gecko’s eyes. Supplement insects appropriately for the animal’s diet and UVB exposure.
Handling and consent
Let a new gecko settle before introducing handling. Begin with short sessions close to the ground. Allow the gecko to step onto your hand rather than grabbing from above. Never restrain or lift by the tail; a dropped tail does not regrow.
Watch the animal. Repeated fleeing, vocalizing, gaping, biting, heavy breathing, or frantic jumping means the session should end. Tolerance is individual, and observation can be a perfectly good relationship.
Health checks
Know the normal pattern for your gecko: appetite, waste, movement, grip, body condition, skin, eyes, mouth, and behaviour. Seek an experienced reptile veterinarian for concerns including:
- persistent refusal of food or unexplained weight loss
- weakness, tremors, poor grip, or a soft or distorted jaw
- wheezing, discharge, open-mouth breathing, or repeated clicking
- swelling, injury, retained shed, abnormal waste, or parasites
- sudden or sustained behavioural change
Routine weights can help reveal change, but the number never replaces observing the whole animal.
Keep learning
Care standards improve as evidence and experience grow. Treat this guide as a strong starting point, continue learning, and adjust care to the individual animal.
