Creating the Perfect Crested Gecko Tank

Choosing the Right Tank

When setting up a habitat for your crested gecko, it’s important to choose the right tank. Consider the size, material, and escape-proof design of the enclosure.


The size of the tank is crucial for the well-being of your crested gecko. A 20-gallon tank is the minimum recommended size for one adult gecko. However, it’s always better to provide more space if possible. A larger tank allows for more climbing and exploring opportunities, which are important for the gecko’s physical and mental stimulation.


Glass terrariums are commonly used for crested geckos. They provide a clear view of your pet and are easy to clean. However, avoid using metal or wooden cages, as they can retain moisture and create an unhealthy environment for the gecko.

Escape-proof Design

Crested geckos are excellent climbers and jumpers, so it’s important to ensure that their enclosure is escape-proof. Make sure the tank has a secure lid or screen top that fits tightly to prevent any possibility of escape.

Setting Up the Habitat

Once you have selected the right tank, it’s time to set up the habitat for your crested gecko. Pay attention to the substrate, temperature and humidity levels, lighting, and the inclusion of decorations and hiding spots.


Choose a substrate that retains moisture but also allows for easy cleaning. A popular choice for crested geckos is coconut fiber substrate. It provides a natural and comfortable surface for your gecko to walk on, while also helping to maintain proper humidity levels in the tank.

Temperature and Humidity

Crested geckos thrive in environments with temperatures between 72-78°F (22-25°C) during the day and a slight drop to 65-70°F (18-21°C) at night. To achieve this, use a reptile thermostat or heat lamp. Additionally, maintaining a humidity level of 50-70% is crucial for crested geckos’ health. You can achieve this by misting the tank regularly and using a hygrometer to monitor humidity levels.


While crested geckos are nocturnal and do not require UVB lighting, a low-wattage bulb or LED light can be used to provide a natural day-night cycle and create a visually appealing habitat. Avoid using bright or direct lighting, as it can stress the gecko.

Decorations and Hiding Spots

Crested geckos are arboreal creatures and love to climb, so it’s important to provide plenty of vertical space and hiding spots. Include branches, vines, and fake plants to create a naturalistic environment. Hiding spots, such as hollow logs or cork bark, are essential for the gecko’s sense of security.

Selecting the Ideal Crested Gecko

When choosing a crested gecko, consider its age and size, overall health, and temperament.

Age and Size

If you’re looking for a pet that is easier to handle, consider getting a juvenile or sub-adult crested gecko, as they tend to be more tolerant to handling and less skittish. However, keep in mind that young geckos will require more frequent feedings and attention.

Overall Health

Check for signs of good health, such as clear eyes, smooth skin, and a healthy appetite. Avoid purchasing a gecko that appears lethargic, has open wounds, or shows any signs of disease or malnutrition.


Observe the gecko’s behavior. A healthy crested gecko should be alert, active, and curious. Avoid geckos that display aggressive behavior or excessive fearfulness, as this can indicate underlying health or temperament issues.

Providing Proper Nutrition

A balanced diet is essential for the overall health and well-being of your crested gecko. Make sure to provide a main diet, supplementary foods, and establish a feeding schedule.

Main Diet

Crested geckos are primarily insectivores, but they can also consume fruit-based commercial diets. A high-quality, complete crested gecko diet should make up the majority of their nutrition. Offer a small amount of the crested gecko diet every other night and remove any uneaten food within 24 hours.

Supplementary Foods

To provide variety and additional nutrients, incorporate gut-loaded insects, such as crickets or mealworms, into the gecko’s diet. Dust the insects with a calcium supplement before feeding to ensure proper calcium intake.

Feeding Schedule

Young crested geckos require more frequent feedings than adults. Feed juveniles every day and gradually decrease to every other day as they mature. Adult geckos can be fed every other day or three times a week.

Maintaining Hygiene

A clean and hygienic tank is essential for the health of your crested gecko. Regular cleaning, proper waste handling, and preventing diseases should be part of your routine.

Regular Cleaning

Perform regular spot cleaning by removing any feces, shed skin, or uneaten food. Every 4-6 weeks, give the tank a deep clean by removing all decorations, washing them with warm soapy water, and sanitizing the tank with a reptile-safe disinfectant.

Handling Waste

To simplify waste handling, you can place a reptile-safe liner at the bottom of the tank. This will make it easier to remove solid waste and minimize odor. Dispose of waste in an appropriate manner and maintain a clean and odor-free habitat.

Preventing Disease

Maintain proper hygiene and environmental conditions to prevent diseases. Regularly monitor your gecko for signs of illness and promptly seek veterinary care if needed. Remember that prevention is key to keeping your crested gecko healthy.

Ensuring Optimal Environmental Conditions

Monitor and maintain the temperature, humidity, and ventilation in your gecko’s tank to provide optimal environmental conditions.

Monitoring Temperature and Humidity

Regularly check the temperature and humidity levels using a thermometer and hygrometer. Make adjustments as necessary to ensure they are within the recommended ranges for crested geckos.


Proper ventilation is crucial to prevent the buildup of stagnant air and mold growth. Ensure that your tank has sufficient airflow without causing drafts or exposing the gecko to direct airflow from fans or vents.

Avoiding Direct Sunlight or Drafts

Direct sunlight can cause overheating, while drafts can lead to temperature fluctuations. Place the tank away from direct sunlight and avoid positioning it near windows or doors where drafts may occur.

Handling and Socializing

Proper handling techniques and regular socialization are important for bonding with your crested gecko and ensuring its well-being.

Proper Handling Techniques

Approach your gecko slowly and gently. Use a gentle touch and avoid squeezing or restraining the gecko too tightly. Support their body by allowing them to walk on your hand or forearm. Avoid sudden movements that can startle or stress the gecko.

Bonding and Socialization

Spend time near the tank, talking softly or playing calming music, to familiarize your gecko with your presence. Gradually introduce handling sessions for short periods, gradually increasing the duration over time. Take cues from your gecko’s behavior, always ensuring that they feel safe and comfortable.

Identifying and Addressing Health Issues

It’s important to be vigilant and knowledgeable about common health problems in crested geckos. Be able to recognize signs of illness and know when to seek veterinary care.

Common Health Problems

Common health issues in crested geckos include metabolic bone disease, mouth rot, shedding problems, and parasitic infections. Regularly check for symptoms such as weight loss, lethargy, loss of appetite, swollen joints, discolored gums, or abnormal shedding.

Signs of Illness

If you notice any abnormal behavior, changes in appearance, or signs of illness, seek veterinary care immediately. Early detection and treatment can greatly increase the chances of a positive outcome.

Seeking Veterinary Care

Find a reptile-savvy veterinarian in your area who can provide expert care for your crested gecko. Regular check-ups and consultations are important for maintaining your gecko’s health and well-being.

Breeding Crested Geckos

Breeding crested geckos can be a rewarding experience, but it requires proper understanding and preparation.

Understanding the Breeding Cycle

Before attempting to breed crested geckos, it’s crucial to understand their reproductive behavior. Males reach sexual maturity at around 15-18 months, while females can breed as early as 8-12 months. Introduce breeding partners slowly and monitor their interactions closely.

Creating the Right Breeding Conditions

Provide optimal conditions for the breeding process, including temperature, humidity, and hiding spots. Offer a laybox with damp sphagnum moss to provide a suitable environment for female geckos to lay their eggs.

Caring for Hatchlings

Once the eggs are laid, carefully remove them and place them in an incubator set to the appropriate temperature and humidity. Monitor the eggs closely and provide proper care for the hatchlings after they emerge.


Creating the perfect crested gecko tank requires careful consideration of size, material, and escape-proof design. Proper habitat setup, nutrition, and hygiene are vital for the health and well-being of your gecko. Regular monitoring, handling, and veterinary care will ensure a happy and thriving pet. With the right knowledge and care, you can provide a comfortable and enriching environment for your crested gecko for years to come.
