Care & Husbandry

African fat-tailed geckos are known for their calm temperament, distinctive thick tail and secretive terrestrial behaviour. This care sheet covers the essential husbandry requirements, including housing, temperature, humidity, feeding, lifespan and common health challenges.

Natural Habitat

The species occurs in western African savanna and associated habitats, where ground cover, rocks and retreats provide shelter. Local conditions vary seasonally. A moist hiding place can differ greatly from the exposed surroundings, so natural humidity should not be represented by keeping every surface permanently wet.

Housing

Adult African fat-tailed geckos (Hemitheconyx caudicinctus) should be housed in a terrestrial enclosure measuring at least 90 × 45 × 45 cm. An enclosure of 120 × 60 × 60 cm or larger is recommended where space allows, providing additional room for exploration, thermoregulation and environmental enrichment.

The enclosure should contain multiple secure hides distributed across the thermal gradient, including a warm hide, a cool hide and a dedicated humid hide. Cork bark, rocks, low branches and other stable furnishings provide additional cover and opportunities for natural exploration. A suitable substrate should retain some moisture and allow digging without remaining continuously saturated.

A shallow water dish containing fresh drinking water should be available at all times. African fat-tailed geckos should generally be housed individually, as territorial behaviour and competition can occur during cohabitation.

A consistent day-night cycle should be provided. Appropriate low-level UVB lighting is recommended, with an approximate exposed-zone UV Index of 0.5–1.5. Shaded areas and secure retreats should remain available so the gecko can regulate its exposure.

Temperature & Humidity

Provide a thermal gradient that allows the African fat-tailed gecko to regulate its body temperature. A local warm surface should reach approximately 32–34°C, while the surrounding warm area should remain around 28–31°C. The cooler portion of the enclosure should remain approximately 22–25°C.

The highest temperature should remain localised rather than maintaining the entire warm hide at the maximum surface temperature. Surface temperatures should be measured separately from ambient air temperatures. Heating equipment should be thermostatically controlled and appropriately installed to prevent overheating and thermal injury.

A natural night-time temperature reduction can be provided, with temperatures generally falling to approximately 20–23°C. Additional night-time heating is generally unnecessary when temperatures remain within a suitable range.

Ambient humidity should generally remain around 50–70%, although natural daily and seasonal fluctuations can occur. A dedicated humid hide should remain available at all times, providing a consistently moist microclimate that supports hydration and normal shedding.

The humid hide should remain moist without becoming waterlogged or unhygienic. Adequate ventilation should be maintained throughout the enclosure so that moderate humidity does not result in persistently wet or stagnant conditions.

Feeding

African fat-tailed geckos are insectivorous and should receive a varied diet of appropriately sized live invertebrates. Suitable feeders include crickets, locusts, roaches, mealworms and other nutritionally appropriate feeder insects. Dietary variety should be provided rather than relying on a single feeder species.

Hatchlings and young juveniles can generally be offered appropriately sized food daily or every other day, with feeding frequency gradually reduced as growth slows. Adults can generally be fed approximately 2–3 times per week. Feeding quantity and frequency should be adjusted according to age, size, activity, reproductive status and body condition.

Feeder insects should be properly gut-loaded and dusted with appropriate calcium and vitamin/mineral supplements. Supplementation should take account of the gecko’s age, diet and effective UVB exposure. High-fat feeder insects should be restricted to help prevent excessive weight gain.

Lifespan

With appropriate housing, nutrition and long-term husbandry, African fat-tailed geckos commonly live for approximately 15–20 years in captivity, with some individuals capable of living longer.

Common Health Challenges

• Metabolic bone disease: Inappropriate calcium and vitamin D3 metabolism resulting from inadequate nutrition, supplementation or UVB provision can impair normal skeletal health.
• Obesity: Excessive food intake or frequent use of calorie-dense feeder insects can cause unhealthy weight gain.
• Retained shed: Inadequate hydration or lack of access to an appropriate humid microclimate can result in retained skin, particularly around the toes and tail.
• Dehydration: Insufficient access to water or inappropriate environmental humidity can compromise hydration.
• Respiratory disease: Inappropriate temperatures, poor ventilation and persistently wet or unhygienic conditions can contribute to respiratory problems.
• Digestive problems and impaction: Ingestion of inappropriate materials, oversized prey, dehydration or unsuitable temperatures can contribute to gastrointestinal obstruction or impaired digestion.
• Thermal injury: Uncontrolled or inadequately protected heating equipment can cause burns or overheating.
• Parasites: Internal parasites and external mites can occur, particularly in newly acquired or exposed animals.
