AFRICAN FAT-TAILED GECKO
Often compared to their Leopard Gecko cousins, African Fat-Tailed Geckos (AFTs) have very different environmental requirements. This interactive guide contains everything you need to help them thrive in a humid, scrubland environment.

🏗️ Cage Requirements & Structural Standards
African Fat-Tailed Geckos (Hemitheconyx caudicinctus) are terrestrial, semi-fossorial lizards native to the humid savannas, scrublands, and rocky riverbeds of West Africa. They require significant floor space over vertical height.
Minimum Enclosure Dimensions:
- Juveniles: 20 Gallon Long (30" x 12" x 12") is the absolute minimum standard.
- Adults (7-9 inches): 40 Gallon Breeder (36" x 18" x 18") is highly recommended for a full-grown adult to ensure a proper thermal gradient.
Provide at least three distinct, low-profile hides: one on the warm side, one on the cool side, and one humid hide (packed with damp sphagnum moss) to facilitate shedding.
AFTs are strictly solitary. NEVER house two males together, as they will fight to the death. While some outdated sources suggest housing females together, it frequently results in severe stress, food competition, and dropped tails. Keep them housed individually for their safety.
☀️ The UVB Standard (Cryptic Baskers)
African Fat-Tailed geckos are crepuscular (most active at dawn and dusk) and largely nocturnal. They exhibit "cryptic basking," exposing their tails or limbs to low-level light. While they can survive with only dietary Vitamin D3, providing proper UVB is highly recommended to prevent Metabolic Bone Disease (MBD) and encourage natural behaviors.
Ferguson Zone Classification:
- ★ Zone 1 (African Fat-Tails): Crepuscular / shade dwellers. Mid-day UVI target of 0.4 to 0.7 (Maximum 1.0).
- Zone 2: Partial shade dwellers (Occasional baskers).
- Zone 3: Open or partial sun baskers.
- Zone 4: Full sun baskers (Extreme desert species).
UVB Requirements:
- Type: T5 HO (High Output) Linear Tube.
- Strength: 2.4% to 7% (e.g., Arcadia ShadeDweller).
- Coverage: The bulb should span no more than 1/2 the enclosure length, positioned over the warm side.
📐 The "Mesh Factor" (Lighting Precision)
A standard screen top will filter out roughly 30% to 50% of UVB. With a 7% T5 bulb resting on the mesh, the optimal basking spot should be roughly 10-12 inches directly below the fixture. Provide plenty of dark hides so they can completely escape the light.
🌡️ Temperature & Crucial Humidity
| Requirement | Specification |
|---|---|
| Basking Surface Temp | 90°F - 95°F |
| AMBIENT WARM SIDE | 85°F - 88°F |
| Cool Side Ambient | 75°F - 80°F |
| Humidity Baseline | 50% - 70% (Higher than Leopard Geckos!) |
| CRITICAL REQUIREMENT | A moist hide (70% - 80%+ humidity) is mandatory for shedding. |
| CRITICAL UPPER LIMIT | NEVER ABOVE 100°F (Surface) |
Heating Method:
Overhead heating (like a Halogen flood bulb or Deep Heat Projector) paired with a slate basking rock is the most natural way to warm their bodies. Heat mats (Under Tank Heaters) only heat the floor, not the air, and should only be used as supplemental heat connected to a thermostat.
🦗 Nutrition & Picky Eaters
African Fat-Tailed Geckos are strict insectivores. They do not eat plants or fruits. They are also notoriously picky eaters compared to other geckos, often refusing worms entirely and holding out for fast-moving prey.
Feeding Schedule
| Age Group | Frequency | Quantity |
|---|---|---|
| Babies (0-6 months) | Daily | 5-7 appropriately sized insects |
| Juveniles (6-12 months) | Every other day | 6-8 appropriately sized insects |
| Adults (12+ months) | 1-2 times per week | 5-7 large insects per feeding |
🦗 The Live Insect Roster
| Category | Insects |
|---|---|
| Primary Staples | Crickets, Dubia Roaches, Silkworms. (AFTs heavily favor crickets due to their movement). |
| Secondary Staples | Black Soldier Fly Larvae (NutriGrubs). |
| Treats (Max 1x a week) | Waxworms (highly addictive). |
While healthy ADULT African Fat-Tailed geckos can consume mealworms and superworms (if they will even accept them), they must be fed responsibly. Their thick, chitinous exoskeletons require optimal belly heat (90°F+) for proper digestion.
NEVER feed mealworms or superworms to juveniles under 6 months old. Their smaller digestive tracts cannot break down the shells efficiently, which frequently causes a FATAL IMPACTION (gut blockage). Stick to softer staples like crickets and small roaches for babies.
Calcium & Vitamin Supplementation
- In-Tank Calcium: Leave a small bottle cap of pure calcium (without D3) in the enclosure at all times. They will lick it as needed.
- If using UVB: Dust insects with pure calcium (No D3) most feedings, and use a Multivitamin with low D3 once every week or two.
- If NO UVB is used: You must dust their insects with Calcium + D3 at almost every feeding, alternating with a multivitamin.
🌿 Safe Substrates & Humidity Retention
Because African Fat-Tails require higher humidity (50-70%), their substrate must be able to hold some moisture without molding.
Recommended Options:
- Paper Towels: Ideal for babies under 6 months, quarantine, or monitoring health. Very easy to clean, but requires more frequent misting to keep ambient humidity up.
- Safe Mix (Adults): A 70/30 mix of Organic Topsoil (fertilizer-free) and Play Sand, often mixed with a bit of Coconut Coir. Mimics their natural scrubland environment and holds moisture perfectly.
- Slate Tile: Holds belly heat beautifully and files down their sharp claws naturally. (Must use a humid hide and regular misting if using tile, as it holds zero humidity).
- Calcium Sand / Vita-Sand: Marketed as "safe and digestible," this is actually a deadly antacid. It neutralizes stomach acid, clumps together in the gut, and causes fatal impaction.
- Reptile Carpets: The fabric loops frequently snag their delicate toes and teeth, leading to ripped-out claws. It also harbors massive amounts of bacteria.
- Crushed Walnut Shells: The edges are incredibly sharp and can cause internal lacerations if swallowed.

🎮 Interactive FAQ Flashcards
👆 Hover or tap the cards below to reveal the answers!
Why is its tail so fat?
Hover to RevealJust like their name implies, AFTs store their fat and water reserves in their thick, bulbous tails. A plump, wide tail is a great indicator of a healthy, well-fed gecko!
Will its tail grow back?
Hover to RevealYes. This is called autotomy. If grabbed or severely stressed, they drop their tail to escape predators. The new tail will grow back, but it often looks like a smooth, turnip-shaped bulb rather than having the original ridges.
Are they just Leopard Geckos?
Hover to RevealNo! While they look similar and are both "eyelid geckos," African Fat-Tails (West Africa) require significantly higher humidity, have larger eyes, shorter snouts, and are generally more docile and slower-moving than Leopard Geckos (Middle East).
Why are its toes turning black?
Hover to RevealThis is caused by stuck shed cutting off circulation to the toe. It is incredibly common without a moist hide and high ambient humidity. Soak them in warm, shallow water and gently remove the shed with a Q-tip to save the toe.
Why did it turn dull and white?
Hover to RevealThey are getting ready to shed. Make sure their moist hide is damp and the tank humidity is at 70%. They will pull the old skin off and eat it! Do not pull the skin off for them.
Why is it making noise?
Hover to RevealAFTs can vocalize! A quiet squeak or chirp is often just a social sound, but a loud scream or bark means they feel extremely threatened and terrified. Back off and give them space.
Why won't it eat mealworms?
Hover to RevealAFTs are notoriously picky eaters. Because they are slower ambush predators, they often heavily prefer fast, jerky, jumping prey to trigger their feeding response. If they refuse worms, switch to crickets or small roaches.
Can I hold my Fat-Tailed Gecko?
Hover to RevealAbsolutely! They are one of the most docile, calm, and handleable reptiles in the world, often even more relaxed than Leopard Geckos. Move slowly, let them walk on your hands, and never grab them by the tail.
