How to Care for Your Texas Banded Gecko

How to Care for Your Texas Banded Gecko

Texas banded geckos (Coleonyx brevis) are small, crepuscular, terrestrial lizards native to the Chihuahuan Desert area of North America. It’s an arid habitat with sandy to stony substrate and sparse vegetation.

Texas banded geckos are typically 4-5” long, with slender bodies and limbs, wedge-shaped head, big eyes, vertical pupils, smooth skin, and an unsegmented tail. They usually have a pale pink to yellow base color with brown to black bands, dark markings, and a speckled underside. Juveniles change from a banded pattern to a combination of bands and spots as they grow into adults. Unlike most geckos, banded geckos have eyelids and don’t have sticky toe pads.

Texas banded geckos are very similar in care to more commonly-kept leopard geckos, but less tolerant of handling, which makes them an intermediate-level pet reptile. With good care, they are likely to live 15 years or more.

Note: Banded geckos may be native to the US, but that’s not a reason to take one from the wild if you want one as a pet. If you want a pet banded gecko, please do the responsible thing and support a breeder’s efforts. Never take reptiles from the wild!

How much space do Texas banded geckos need?

A single Texas banded gecko should be housed in no smaller than a 20 gallon (30” x 12” x 12” or 24” x 18” x 12”) terrarium. This is larger than the typical recommendation, but anything smaller will be unable to support all of the equipment that is needed to create a healthy environment for your gecko.

Cohabitation (keeping multiple geckos in the same terrarium) is possible with this species. Unless you plan to breed, only house females together, and never put more than one male in the same enclosure, as they will fight! A 20 gallon terrarium will fit up to 3 geckos, but it’s better to size up to 40 gallons (36” x 18” x 18”) for housing multiples.

Do Texas banded geckos need UVB?

Texas banded geckos are crepuscular, which means that they are most active from dusk to dawn, with their primary activity window being for a few hours after sunset. Technically banded geckos can survive without UVB lighting as long as they get supplemented with vitamin D3, but the fact remains that they can’t thrive without it. Aside from helping provide a day/night cycle, UVB is also good for your gecko’s overall wellbeing.

It’s best to provide low-strength UVB lighting as part of your gecko’s enclosure. The best UVB bulbs for banded geckos are:

  • Zoo Med Compact Coil Reptisun 5.0, 26w
  • Zoo Med T8 Reptisun 5.0, 18”
  • Arcadia ShadeDweller UVB kit

The UVB bulb should be roughly half the length of the enclosure and housed in a fixture with a reflector. If you are using a compact coil bulb, it must be mounted horizontally rather than vertically. Place the fixture on the basking side along with the heat lamp.

UVB is blocked by glass and plastic, so you can’t give your gecko UVB by placing its terrarium in front of an open window. This can also make your enclosure dangerously hot by creating a greenhouse effect! Also make sure that the fixture your UVB bulb is in does not have a clear plastic or glass bulb cover.

Lights should be on for 8 hours/day during winter, and 14 hours/day during summer to simulate seasonal changes in day length.

What basking temperatures do Texas banded geckos need?

Texas banded geckos should have a warm hide temperature between 90-95°F, as measured by a digital probe thermometer with the probe placed inside the warm hide. Ambient temperatures throughout the rest of the enclosure should stay between 72-90°F. 

It’s best practice to provide heat for your gecko with two sources: a heat lamp and a heat mat. The heat lamp is for warming the air of the enclosure and providing short-wavelength infrared (heat) for the gecko to use as desired. The heat mat is for heating the warm hide to optimal temperature. 

For the heat lamp, use a low-wattage white heat bulb such as the 60w Exo Terra Daytime Heat Lamp placed on one side of the enclosure. If it's too warm, try a plug-in lamp dimmer or rheostat. If it's too cool, you need a higher-wattage bulb. Do not use ceramic heat emitters (CHEs), red bulbs, or blue bulbs, as these are not as effective. Place the gecko’s warm hideout/cave below the heat lamp.

If your warm hide doesn’t get warm enough with the heat lamp alone, you will need a heat mat. The heat mat should be roughly the same size or a little larger than the hide itself, placed under the hide and covered with enough substrate to prevent direct contact. You must plug your heat mat into a thermostat to prevent it from overheating, which can be fatal! Place the thermostat probe inside the warm hide to accurately control temperature.

Heat sources should be turned off at night. Nighttime temperatures can drop as low as 65°F.

What humidity levels do Texas banded geckos need?

Texas banded geckos need a low-humidity environment with access to a humid microclimate for best health. Average humidity should be 30-40%, as measured by a digital probe hygrometer with the probe in the middle of the terrarium. 

However, you will also need to provide a humid hideout lined with moistened substrate or coconut fiber and placed on the cool end of the enclosure. The humid hideout should have 70% humidity or higher at all times.

It’s beneficial to mist the cool side of the enclosure with a sprayer 2-3x/week in order to raise humidity and provide an extra source of drinking water in the form of water droplets. As long as the terrarium has good ventilation, the misting will not cause any problems for your gecko’s health and will help ensure healthy levels of hydration.

What substrate is good for Texas banded geckos?

Substrate covers the floor of your gecko’s terrarium and helps make the enclosure more attractive, but it also helps maintain higher humidity levels and provides something for your gecko to dig in. Solid substrates like slate tile and terrarium mats are popular because of the common myth that geckos will get impacted if housed on a “loose”-type substrate (this only happens when the animal is already unhealthy due to poor husbandry). If you’re nervous, you can certainly use a solid substrate, but they have some significant disadvantages:

  • Solid substrates need to be scrubbed frequently
  • Solid substrates don’t cushion your pet’s joints
  • Solid substrates offer no enrichment value

It’s ideal to use a substrate that imitates the “substrate” that the reptile naturally lives on in the wild. Aside from promoting healthy humidity levels (solid substrates tend to create an extremely dry environment), naturalistic substrates also provide a medium for your gecko to dig in as desired. For Texas banded geckos, that means it should be sand or sandy soil.

We recommend the following substrates for Texas banded geckos:

Substrate should be at least 3” deep and completely replaced every 3-4 months. Remove poop and urates daily, along with contaminated substrate.

What décor can you use in a Texas banded gecko terrarium?

It’s terribly boring (and even stressful!) for a gecko to be stuck in an enclosure with nothing in it except substrate and a water bowl. It doesn’t matter how big the enclosure is if you don’t put things in it for your pet to use and interact with. 

At bare minimum, you will need at least two “caves” for the gecko to hide in. However, it’s best to include other items, such as:

It’s also best practice to cover three sides of the enclosure to help the gecko feel more secure in its environment.

What do Texas banded geckos eat?

Banded geckos are insectivorous, which means that they need a diet of insects in order to get the nutrition that their bodies need. How often these geckos need to eat depends on age: Juveniles should be fed daily, and adults fed every other day.

One meal should be 2 appropriately-sized bugs per 1 inch of your gecko’s length, or however much they can eat in 15 minutes. The largest insect that a banded gecko should be fed should be slightly smaller than the gecko’s head.

Feeder insects for banded geckos: dubias, discoids, crickets, black soldier fly larvae, hornworms, mealworms, mealworm beetles

Supplements

You will also need calcium and vitamin supplements to prevent your gecko from developing a deficiency. We recommend Repashy Calcium Plus LoD, lightly dusted on all of your gecko’s feeder insects. Feeder insects should be gutloaded and hydrated for at least 24 hours before mealtime.

Water

Of course, don’t forget a small water bowl for your gecko to drink from! Change the water daily and scrub the bowl with a reptile-safe disinfectant weekly, or whenever it becomes soiled.

Do Texas banded geckos like to be handled?

Banded geckos are not as handleable as leopard geckos, and generally prefer to be left alone, as handling can be stressful for them. Plus, they’re quite small and fast-moving, so handling is likely to be stressful for you, too. Enjoy watching them instead! If you want to interact with your gecko, try hand-feeding them with a pair of soft-tipped feeding tongs.
