African Fat-Tailed Gecko (Hemitheconyx caudicinctus) Care Sheet

​A complete guide for the successful keeping of this docile, high-humidity terrestrial gecko from West Africa, often considered a great alternative to the Leopard Gecko.

​1. Overview & Natural Habitat

  • ​Common Name: African Fat-Tailed Gecko, AFT

  • ​Scientific Name: Hemitheconyx caudicinctus

  • ​Natural Habitat: Arid and semi-arid regions of West Africa, but they seek out humid microclimates, hiding under leaf litter, rocks, and in humid burrows. They are terrestrial.

  • ​Size: Adults typically reach 18 – 23 cm (7 – 9 inches), including the tail.

  • ​Lifespan: 15 – 20+ years in captivity.

  • ​Temperament: Extremely docile, shy, and prone to “waving” their fat tail when stressed or curious. They are crepuscular/nocturnal (most active at dusk and dawn).

​2. Vivarium/Enclosure

​African Fat-Tailed Geckos are terrestrial and require ample floor space with an emphasis on creating humid environments.

  • ​Minimum Enclosure Size (Adult): 75 x 45 x 45 cm (30 x 18 x 18 inches) or equivalent (approx. 30-gallon breeder style). Larger is always recommended.

  • ​Enclosure Type: Glass terrariums or wooden/PVC vivariums are suitable, though PVC is generally better for humidity retention.

  • ​Hides (Minimum of 3):

    • ​Warm Hide: Located on the heated side for digestion.

    • ​Cool Hide: Located on the unheated side for regulating temperature.

    • ​Humid Hide (Crucial): This must be the warmest hide and kept continuously moist (with moss or damp substrate) to provide the high humidity they need for health and shedding.

  • ​Enrichment: Provide flat slate, cork bark, and sturdy branches for hiding and climbing small distances.

​3. Substrate

​The substrate must be able to retain moisture to support the required humidity levels.

  • ​Best Natural Mix: A mix of 70% Organic Topsoil and 30% Peat Moss or Coconut Fiber (Coco Coir), laid at a depth of at least 5 – 10 cm (2-4 inches). This mix allows for natural burrowing.

  • ​Solid/Temporary: Paper towels or non-adhesive shelf liner are suitable for quarantine or hatchlings.

  • ​Avoid: Pure sand, calci-sand, or reptile carpet.

​4. Heating & Temperature

​AFTs require a thermal gradient but thrive at slightly lower basking temperatures than Leopard Geckos.

  • ​Primary Heat Source: A Deep Heat Projector (DHP) or a Ceramic Heat Emitter (CHE) controlled by a dimming or pulse thermostat is recommended.

  • ​Basking Surface Temp (Warm Spot): 30°C – 32°C (86°F – 90°F). This should be measured directly on the substrate surface of the warm hide.

  • ​Cool Ambient Side: 24°C – 27°C (75°F – 80°F).

  • ​Night Time: Temperatures can safely drop to 21°C (70°F). No heat is typically needed unless ambient room temperatures drop below this.

  • ​:red_exclamation_mark: Important Note: Always use a Thermostat to regulate all heating elements to prevent overheating and burns.

    ​5. Lighting & UV

    ​UVB is beneficial for this species, especially since they are active at dawn and dusk.

    • ​UVB Light: A low-level UVB source is recommended (e.g., a 5-6% T5 linear fluorescent tube).

    • ​UV Index (UVI): Aim for a UVI of 0.5 to 1.5 in the basking area.

    • ​Photoperiod: Provide a consistent 12-14 hour day/night cycle. All lights should be off at night.

    ​6. Humidity & Hydration

    ​Humidity is the most crucial difference between AFTs and Leopard Geckos. They require a much higher level.

    • ​Ambient Humidity: Must be maintained between 60% and 80%. Use a digital hygrometer to monitor this.

    • ​Misting: Lightly misting the enclosure (avoiding soaking the animal) in the evening will help increase the humidity levels overnight.

    • ​Humid Hide: The humid hide must be checked daily and kept constantly moist (near 90% humidity) and warm. This is vital for hydration and shedding success.

    • ​Water: A shallow, easily accessible dish of fresh, clean water must be available 24/7.

    ​7. Diet & Feeding

    ​African Fat-Tailed Geckos are insectivores, very similar to Leopard Geckos in their feeding habits.

    • ​Staple Feeders (Variety is Key!): Crickets, Dubia Roaches, Mealworms, and Black Soldier Fly Larvae (Calci-Worms).

    • ​Treat Feeders (Offer Sparingly): Waxworms and Superworms.

    • ​Feeder Size: Insects should be no larger than the space between the gecko’s eyes.

    • ​Feeding Schedule:

      • ​Juveniles (under 6 months): Feed daily.

      • ​Adults (over 1 year): Feed 2-3 times per week, or every 3-4 days.

    ​Supplementation:

    • ​Calcium Powder (Pure): Dust insects at every feeding.

    • ​Calcium with D3 and Multivitamin: Alternate use as directed by the product instructions (e.g., D3 2x a month, Multivitamin 1x a month).

    • ​:white_check_mark: Gut Loading: All feeder insects must be fed nutritious, high-quality food (gut loaded) for 12-24 hours before being offered to your gecko.

      ​8. Handling & Temperament

      • ​Taming: AFTs are generally docile but can be shyer and more skittish than Leopard Geckos. They may “tail wave” when agitated.

      • ​Handling: Keep sessions short and gentle. They are prone to dropping their tail if grabbed or startled (it will regenerate, but it’s best avoided). Always support their body fully.

      • ​Hygiene: Always wash your hands thoroughly before and after handling the gecko or working in its enclosure.
