Crested geckos love to climb, which is why any enclosure you consider needs to have high walls to reduce the risk of your pet gecko escaping.

A single adult crested gecko, on the other hand, do well when housed in at least a 10-gallon enclosure complete with a screen lid. The larger the tank, the better your display will be.

Effective Lighting

Glass enclosures remain a preferred choice over wood and other materials, due to the fact it is able to maintain humidity levels.

With your tank selected, you need to focus on lighting.

UVB lighting can be included, though this a controversial subject with some enthusiasts believing UVB isn’t needed, while others firmly believe in UVB. Your gecko comes from the rain forests, where they have access to UVB.

While the argument is still in full swing, providing UVB through the branches an provide a safe, natural and secure habitat where your gecko can thrive.

Quality Substrate

Lighting should be offered for twelve hours each day.

It’s recommended to use a timer to ensure that your gecko has access to the right amount of daylight.

Substrate is an important decision to make, you can use paper towel or newspaper, which many crested geckos opt for.

The problem is that with the moisture in the cage, they can become messy.

Eco earth is the best option, especially if you intend to use real plants to complete your tank design.

Thermometers and Hydrometers

By now you should have your cage placed where you want it with your lighting and UVB lights.

You will need to place your substrate and plants, while placing your thermometer on the tank to ensure you stay at the desired temperature of 78 to 82ºF (25 to 28ºC).

You will want a hydrometer to ensure you keep the tank at the desired humidity levels of seventy percent.


When placing your hide, remember that crested geckos are climbers, they don’t spend much time on the ground, so you will want to create a hide that is safe and higher up off the ground, a place where your gecko can get some quiet time and rest.

Placing a hide on the enclosure surface will probably just be ignored.

Feeding Ledge

A feeding ledge needs to be placed where your gecko can eat with confidence without having to venture to the cage surface.

Feeding ledges are a great addition to your setup. It provides a place for a feeding bowl and water bowl with the flexibility that you can place it anywhere in your tank with ease.

Crested Gecko Tank Cleaning

It is imperative that you clean and disinfect your crested gecko tank and all accessories on a regular basis. This avoids unwelcome parasites and ensures your gecko remains healthy.

Cleaning is not a nightmare process, in fact it’s relatively quick and easy once you know what you are doing.

The first step is to find somewhere safe to house your gecko while you clean the cage. You are then going to want to remove everything, place it in a plastic bucket or drum, so you can clean it later.

Ensure all substrate is removed and disposed of.

If you are using eco earth bricks, you will want to start getting those ready, mixing the brick with water and allowing it to soak up the water to provide beautiful earth to complete your rain forest design.

Wash out the inside of the vivarium using a reptile disinfectant. Always make sure you rinse and dry thoroughly.

You are going to want to use the same disinfectant to clean food and water bowls, fake plants and hides.

Always ensure everything has been rinsed thoroughly before placing it back in the tank.

Once you are happy, you can start by adding your substrate and build your vivarium up with plants, feeding ledge and anything else you have in there before adding your gecko.

Humidity Requirements

Crested geckos come from the rain forests where they are used to high humidity levels.

You must invest in a hydrometer, which will enable you to ensure your humidity levels are met with confidence.

Humidity levels for a crested gecko can be between 60% to 80%.

There are numerous ways to ensure you maintain your humidity levels, starting by selecting a glass terrarium and using water spray to mist the tank from time to time.

In addition to this, you want to achieve the best humidity levels by selecting the right substrate.

Avoid wood shavings. With the moisture within the tank, wood shavings can get too wet and over time turn to mold.

Eco Earth is the safety substrate when looking to achieve the best humidity levels.
