How Do I Set up Gecko Terrariums?

Setting up gecko terrariums isn’t a difficult task. The terrarium size depends upon the age, sex, and number of geckos. Regardless of whether the habitat is for one gecko or several, you’ll need to supply the right kind of flooring, called substrate, and uneven heat. Geckos, despite their fierce demeanors and their ability to terrify human children by rolling their eyes in complete circles, also need hiding places for when they become inexplicably shy.

Many lizards have the kind of feet that make superheroes jealous because they can take a casual stroll up a wall and across a ceiling. Geckos, although they might inspire superhero jealousy for other reasons, lack the adhesive lamellae that permits these magical feats. That means that, unless you’ve got a furry and curious pet or a curious child, furry or not, gecko terrariums really don't need lids because the gecko can’t escape. Ventilation is important, so if a lid is used, it should be entirely screened to allow air flow.

The terrarium can be a purchased piece that is retrofitted to suit the gecko’s needs, or it can be built from wood and glass. The substrate is very important because this is where the gecko will spend most of its time. Under no circumstances should the gecko’s habitat be lined with sand, because if the gecko ingests it, there’s a good chance it will become intestinally impacted, which could potentially kill the lizard. Safer bets include special nontoxic carpet that can be purchased at a pet store, newspaper, or pea gravel.

Gecko terrariums are sized according to the number and ages of their occupants. Full-grown geckos require about 15 gallons (about 58 liters) per gecko; be aware that, while housemates are fine, two mature males might hurt each other by practicing their professional wrestling moves. Teenage geckos are comfortable with 10 gallons (about 38 liters) of sprawling-around room. If you’re housing hatchlings, a translucent, plastic shoebox is about right, as long as holes have been drilled all the way around.

Lizards love to warm themselves in the sun, and when there isn’t one, they need an acceptable substitute. Like people, they want to be able to cool off when the heat’s too much, so the habitat should offer gradient heat that ranges up to 84 degrees Fahrenheit (31.1 degrees Celsius). A reflector lamp is an option, but it will need monitoring. Gecko terrariums can be heated with undertank heaters that will cost a bit more, but they minimize the inconvenience and possible danger of a reflector lamp that has tipped over.

Feel free to make your gecko’s home homey with some pet store greenery. A big rock or two gives the gecko the chance to scramble. A cardboard paper towel roll will make a fun hideout for a gecko too!

The size of the terrarium depends on the species of gecko. For smaller species like leopard geckos, a 10-20 gallon tank is suitable for one or two individuals. Larger species, such as tokay geckos, may require a 20-30 gallon tank. Always ensure ample space for climbing, hiding, and exploring to promote natural behavior and well-being.

Choosing the right substrate is crucial for your gecko's health. For arid species like leopard geckos, a paper towel, tile, or reptile carpet is recommended to prevent impaction. For tropical species, coconut fiber or peat moss can maintain humidity. Avoid sand and small gravel, which can cause digestive blockages if ingested.

Maintaining proper humidity is species-specific. Tropical geckos typically require 70-80% humidity, which can be achieved with regular misting, live plants, and a water dish. Arid species need lower humidity, around 30-40%. Use a hygrometer to monitor levels, and adjust your misting schedule and ventilation accordingly to maintain the ideal range.

Geckos generally need a temperature gradient with a basking spot of 85-90°F and a cooler area around 70-75°F. Nighttime temperatures can drop slightly. Most geckos do not require UVB lighting if they receive a diet supplemented with vitamin D3, but it can benefit their overall health. Always use a thermometer to monitor temperatures within the terrarium.

Spot cleaning should be done daily to remove waste and uneaten food. A more thorough cleaning, including changing the substrate and disinfecting the terrarium, should be done monthly. Regular cleaning prevents the buildup of bacteria and parasites, ensuring a healthy environment for your gecko.

Enrichment is key to a gecko's health and happiness. Include multiple hiding spots, climbing branches, rocks, and foliage to mimic their natural habitat. For arboreal species, vertical space and sturdy plants are essential. Providing a variety of textures and features encourages natural behaviors like climbing and exploring, which is beneficial for their physical and mental well-being.
