Crested geckos may be cold-blooded, but they’re warm-hearted. And creating the perfect environment for them to thrive can be surprisingly simple, as long as you’ve got the basics right. 

The key is to build a safe, comfortable space that suits their natural lifestyle. Crested geckos are arboreal, which means they live up in trees, so their enclosure needs to offer height, climbing opportunities and that all-important forest feel.  

Because crested geckos are climbers, height matters more than floor space. For a single adult gecko, the vivarium should be at least 45 x 45 x 60cm tall. 

It should be placed in a quiet room, away from direct sunlight and cold draughts. Good ventilation is important too, as it helps stop the air becoming too humid and stale. And while it might be tempting to keep them close by, a bedroom usually isn’t ideal - crested geckos are nocturnal, so they’ll be most active when you’re trying to sleep. 

They’re also solitary animals, so they shouldn’t be housed together.

Crested geckos do best in moderate temperatures. During the day, aim for an ambient temperature of around 20-25°C, with a warmer basking area of around 25-28°C. At night, temperatures can drop to around 18-22°C. 

If your room tends to run cool, you can use a low-wattage ceramic heat lamp, a heat mat or a low-output heat bulb to keep conditions comfortable. Any heat source should always be controlled with a thermostat. 

It’s also important to monitor temperatures properly using a digital thermometer. And make sure your gecko can’t come into direct contact with any heating equipment - all heat sources should be positioned safely outside the enclosure.

Lighting plays an important role in supporting your gecko’s natural behaviour. A low-level UVB tube, around 2-5%, can help with calcium metabolism and overall wellbeing. 

You’ll also want to provide a consistent day and night cycle, with roughly 8-12 hours of light each day. Low-power LED lighting works well for this and helps keep the routine nice and steady. 

Crested geckos come from tropical rainforest environments, so humidity is a big part of keeping them healthy. Aim for humidity levels of around 60-70%. 

A hygrometer is the best way to monitor this accurately. To keep levels up, lightly mist the enclosure once or twice a day, especially in the evening, to mimic those natural rainforest conditions. 

Crested geckos often drink water droplets from leaves, but they should still always have access to a shallow water bowl as well.

Once the temperature, lighting and humidity are sorted, it’s time to build the enclosure itself. 

For substrate, choose moisture-retaining materials such as coco fibre or orchid bark. These help maintain humidity and create a natural floor layer. 

Then add plenty of vertical décor. Branches, vines, cork bark and dense plant cover - either real or artificial - all help create a more natural, enriching space. Crested geckos love to climb, so these features are essential rather than decorative. 

It’s also important to include multiple hiding spots. These help your gecko feel secure and can reduce stress, making the vivarium feel like a safe little slice of rainforest.

When it comes to feeding, crested geckos do well on specialised complete powdered diets. These are designed to provide balanced nutrition and are simple to prepare. 

You can also offer occasional live insects as enrichment. 

Just make sure you keep the enclosure tidy. Uneaten powdered food should be removed after about two days, and any leftover live insects should be taken out too. Crickets and other insects can nip your gecko if they’re left in the enclosure. 

A good crested gecko vivarium should be tall, well-ventilated and carefully set up with the right heating, lighting and humidity. Add suitable substrate, plenty of climbing structures and secure hiding places, and you’ll have created a comfortable home that supports your gecko’s natural behaviour from day one. 

Get the setup right, and your gecko will have everything they need to settle in and thrive.
