What are West African Fat-Tailed Geckos?
The West African Fat-Tailed Gecko (Hemitheconyx caudicinctus) is a gecko species native to the savannas and arid grasslands of West Africa. In Japan, it's affectionately known as "Nishi-Afu," and it has recently gained attention as a popular ground-dwelling gecko alongside the Leopard Gecko. Its thick, stocky tail (which stores fat reserves), dark round eyes, and docile temperament make it relatively easy to handle. However, it requires slightly higher humidity than Leopard Geckos, making proper environmental setup essential.

Differences from Leopard Geckos
While West African Fat-Tailed Geckos and Leopard Geckos are often compared, their care requirements differ significantly. Understanding these differences will help you choose the right species and understand the necessary equipment and difficulty level.
| Aspect | West African Fat-Tailed Gecko | Leopard Gecko |
|---|
| Native Habitat | West Africa (Nigeria, etc.) | Central Asia to Pakistan |
| Body Length | 20–28 cm (including tail) | 18–25 cm |
| Ideal Humidity | 60–80% | 30–50% |
| Ideal Temperature (Basking Spot) | 30–32°C | 28–32°C |
| Eye Characteristics | Large black eyes (twilight active) | Vertical pupils (nocturnal) |
| Morph Variety | Relatively limited | Extremely diverse |
| Price Range | Relatively high | Wide range |
| Beginner Difficulty | Moderate-High | Easy |
The biggest difference is humidity. West African Fat-Tailed Geckos are adapted to seasonal rains in their native habitat. Insufficient humidity can lead to shedding problems and health issues. If you master humidity management, West African Fat-Tailed Geckos are actually very easy to care for.

Enclosure Selection and Setup
Enclosure Size
The minimum enclosure size for one adult is 45 cm (width) × 30 cm (depth) × 30 cm (height). An enclosure of 60 cm or wider is recommended to provide adequate space for movement.
Glass or plastic enclosures are standard. West African Fat-Tailed Geckos are good at escaping, so choose an enclosure with a securely fastening lid.
Bedding Selection
Using bedding suitable for humidity retention is essential.
- Coco Fiber (Coco Husk): Excellent moisture retention. Spread 5–8 cm thick.
- Bioactive Soil: Creates a naturalistic environment and helps maintain wet zones.
- Paper Towels: Easy to keep clean; ideal for hatchlings or recovering individuals.
Sand-based beddings carry the risk of impaction and are not recommended, even for adults.
The Importance of Hides
West African Fat-Tailed Geckos rely heavily on hiding places. Install at minimum a "dry hide" and a "humid hide (wet hide)."
- Dry Hide: Place on the cool side of the enclosure. Terracotta hides offer a good balance of airflow and moisture retention.
- Wet Hide: Place in the center or near the basking spot. Fill the interior with damp sphagnum moss.
The wet hide is crucial for preventing shedding problems. Neglecting it frequently results in incomplete sheds, so maintain it consistently.

Temperature and Humidity Management
Temperature Setup
Create a temperature gradient across the enclosure, as is standard for all reptiles.
| Zone | Target Temperature |
|---|
| Basking Spot (under heat source) | 30–32°C |
| Warm Zone | 27–30°C |
| Cool Zone | 24–26°C |
| Night | 22–25°C |
Use an under-tank heater as your primary heat source, covering approximately one-third of the enclosure floor with the opposite side serving as the cool zone. Always control the temperature with a thermostat.
In winter, an under-tank heater alone may not maintain adequate nighttime temperatures. In such cases, use a top heat source or auxiliary heating.
Humidity Setup
Aim for 60–80%. The dry zone should be 50–60%, and the interior of the wet hide should ideally be 80–90%.
- Mist the enclosure walls once daily to every other day.
- Monitor bedding moisture and hydrate as needed.
- Replace or re-dampen sphagnum moss in the wet hide weekly.
Install a humidity gauge in the enclosure and monitor it regularly. Humidity below 50% sharply increases the risk of shedding problems.

Feeding Types and Methods
Primary Food Insects
West African Fat-Tailed Geckos generally have strong appetites and should be fed nutritious insects.
| Insect Type | Characteristics |
|---|
| Crickets (Two-Spotted & House Crickets) | Optimal staple diet with good nutritional balance |
| Dubias | Low-odor, easy to manage, high-protein; excellent as a main feeder |
| Silkworms | Good digestibility; effective for recovering or anorectic individuals |
| Hornworms (Waxworms) | High fat content; use during recovery or breeding conditioning |
| Mealworms | High chitin content; feed as occasional treats |
Feeding Frequency and Calcium Supplementation
- Hatchling to Young (up to 6 months): Every 2–3 days, as much as they eat
- Subadult (6 months–1 year): Every 3–4 days, 5–8 insects
- Adult (1+ year): 1–2 times per week, 8–12 insects
Before each feeding, dust food insects with calcium (without D3). Switch to calcium with D3 once or twice weekly, and use multivitamins 2–3 times per month. If using UVB lighting, reduce D3 supplementation frequency.
Addressing Anorexia
West African Fat-Tailed Geckos may stop eating due to environmental changes or breeding season (especially males).
- First, verify that temperature and humidity are appropriate.
- Check that shelters are adequately provided.
- Try different food types (crickets vs. dubias).
- If anorexia persists for over 2 weeks with significant weight loss, consult a veterinarian.

Morphs (Varieties)
While West African Fat-Tailed Gecko morphs are less diverse than Leopard Gecko morphs, they are increasing rapidly.
| Morph Name | Characteristics |
|---|
| Normal (Wild Type) | Brown striping; natural appearance |
| Whiteout (WA) | Pale overall with faint striping |
| Zero | Striping nearly absent; pale to light coloration |
| Orb | Completely white eyes (also called Blue Eye). Vision effects debated |
| Patternless | No stripes; uniform coloration; changes with growth |
| Tangerine | Strong orange coloration |
| Albino | Melanin deficiency; red eyes |
Combination morphs similar to Leopard Gecko "Super Mack Snow" also exist. Prices range from 5,000–15,000 yen for normal morphs, with rare combo morphs sometimes exceeding 50,000 yen.

Breeding
Breeding Age and Preparation
- Males: 12–18 months or older, 60g or heavier
- Females: 18–24 months or older, 80g or heavier
Females consume significant calcium during egg production, so strengthen supplementation with calcium and multivitamins during the 2–3 months before breeding. Avoid breeding individuals with poor body condition or health.
Cooling (Brumation)
Light cooling stimulates breeding drive in West African Fat-Tailed Geckos.
- Gradually lower temperature from October–December (basking spot 27–28°C, cool zone 20–22°C).
- Reduce feeding to half.
- Maintain for 4–6 weeks, then gradually return to normal temperatures.
Provide water continuously during cooling. Individuals with health concerns may breed without cooling.
Pairing and Egg-Laying
After cooling, house the male and female together (supervised pairing for 1–2 hours is recommended). After confirmed mating, separate the female and provide an egg-laying box filled with vermiculite or damp sphagnum moss.
Egg-Laying Characteristics
- 2 eggs per clutch (almost always 2)
- 3–5 clutches per year
- Interval between clutches: 4–6 weeks
Incubate eggs at 28–30°C with 80–90% humidity. Incubation period is approximately 60–90 days.
Hatchling Care
Wait 1–2 days after hatching before the first feeding attempt. Small crickets (under 1 cm) are ideal. Always provide shelters and wet hides.

Health Management and Precautions
Regular Health Checks
- Shedding: Check for remaining shed skin on toes, tail, and around eyes. If present, gently remove in warm water.
- Body Weight: Record body weight monthly. Sudden weight loss indicates health problems.
- Defecation: No bowel movement for over a week suggests constipation. Check temperature and try a warm bath.
Common Illnesses
| Illness/Symptom | Cause | Treatment |
|---|
| Incomplete Shedding | Low humidity or malnutrition | Warm bath + strengthen wet hide |
| Metabolic Bone Disease (MBD) | Calcium or D3 deficiency | Increase supplements, provide UVB |
| Cryptosporidium | Parasite infection | Veterinary consultation (difficult to treat); isolate individual |
| Impaction | Bedding ingestion | Veterinary consultation |
| Respiratory Infection | Low temperature and high humidity | Improve temperature; veterinary consultation |
Find a veterinarian experienced with exotic animals or reptiles before acquiring your gecko. This is strongly recommended.
