What Are West African Fat-tailed Geckos
West African Fat-tailed Geckos (Hemitheconyx caudicinctus) are members of the gecko family that inhabit savannas and arid grasslands of West Africa. In Japan, they are known by the affectionate nickname "West African Fat-tails," and alongside Leopard Geckos, they have recently gained attention as popular ground-dwelling geckos.
They are characterized by their thick, stocky tail (a fat tail that stores nutrition), large dark eyes, and calm disposition, making them relatively easy to handle. Since they require slightly higher humidity than Leopard Geckos, it is important to have a good understanding of the setup requirements for their habitat.
Differences from Leopard Geckos
West African Fat-tails and Leopard Geckos are often compared species, but their environmental care requirements differ. The differences between Leopard Geckos and West African Fat-tails are shown in the table below. Since the choice between the two affects care difficulty and required equipment, it is important to understand the differences beforehand.
| Aspect | West African Fat-tailed Gecko | Leopard Gecko |
|---|
| Native Region | West Africa (Nigeria, etc.) | Afghanistan to Pakistan to Northwest India (South Asia) |
| 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 dark eyes (crepuscular) | Vertical pupils (nocturnal) |
| Morph Varieties | Relatively few | Extremely numerous |
| Price Range | Somewhat higher | Wide range |
| Difficulty for Beginners | Somewhat difficult | Easy |
The biggest difference is "humidity." West African Fat-tails are adapted to the seasonal rainy season of their native habitat, and excessive dryness can easily lead to shedding problems and health issues. If you are skilled at humidity management, West African Fat-tails are very easy geckos to care for.
Enclosure Selection and Setup
Enclosure Size Guidelines
The minimum enclosure size required for one adult is 45 cm wide × 30 cm deep × 30 cm tall. To provide sufficient space for movement, an enclosure of 60 cm wide or larger is recommended.
Glass or plastic enclosures are common. Since West African Fat-tails are skilled at escaping, choose an enclosure with a securely fastened lid.
Substrate Selection
Using a substrate suitable for maintaining humidity is important.
- Coconut Husk (Coco Fiber): Highly absorbent and recommended. Lay 5–8 cm deep.
- Bioactive Soil: Allows care closer to natural conditions. Also effective for maintaining wet zones.
- Paper Towels: Easy to keep clean and suitable for hatchlings or individuals undergoing treatment.
Sand-based substrates are not recommended, even for adults, due to the risk of impaction from accidental ingestion.
Importance of Shelters
West African Fat-tails place great importance on hiding places. Install at least two types of shelters: a "dry shelter" and a "humidity shelter (wet hide)."
- Dry Shelter: Place on the cool zone side of the enclosure. Unglazed ceramic shelters offer a good balance of breathability and moisture retention.
- Wet Hide: Place in the center to hot spot side of the enclosure. Fill the interior with moist sphagnum moss.
Wet hides are essential for preventing shedding problems. Neglecting to provide them frequently results in improper sheds, so always maintain them.
Temperature and Humidity Management
Temperature Setup
Create a "temperature gradient" that is important across all reptiles.
| Zone | Target Temperature |
|---|
| Hot Spot (Under Basking Light) | 30–32°C |
| Warm Zone | 27–30°C |
| Cool Zone | 24–26°C |
| Nighttime | 22–25°C |
Use a panel heater (under-tank heater) as the basic heating device. Cover approximately one-third of the enclosure bottom, with the opposite side serving as the cool zone. Always control temperature with a thermostat.
In winter, a panel heater alone may not maintain adequate nighttime temperatures. In such cases, supplementary heating such as an overhead heater or greenhouse heater should be used.
Humidity Setup
Aim for 60–80% humidity. Ideal levels are 50–60% in dry zones and 80–90% inside wet hides.
- Mist the enclosure walls with a spray bottle daily to every two days.
- Provide water to the substrate as needed based on dryness levels.
- Replace or re-moisten the sphagnum moss in the wet hide once a week.
Place a hygrometer in the enclosure and monitor it regularly. When humidity drops below 50%, the risk of improper shedding increases sharply.
Prey Types and Feeding Methods
Main Prey Insects Available
Most West African Fat-tails have voracious appetites and should be fed mainly nutritious insects.
| Prey Type | Characteristics |
|---|
| Crickets (Two-spotted & House Crickets) | Ideal as a staple food. Good nutritional balance. |
| Dubia Roaches | Low odor, easy to manage, high protein. Excellent as a main food source. |
| Silkworms (Bombyx mori larvae) | Easily digestible and effective for recovering or anorexic individuals. |
| Honey Worms (Galleria mellonella larvae) | High in fat. Used for conditioning recovering individuals and pre-breeding preparations. |
| Mealworms | High in chitin, can burden digestion. Offer as treats only. |
Feeding Frequency and Calcium Supplementation
- Hatchlings to Juveniles (up to 6 months): Feed every 2–3 days, as much as they will eat.
- Sub-adults (6 months to 1 year): Feed every 3–4 days, approximately 5–8 insects.
- Adults (1 year and older): Feed 1–2 times per week, approximately 8–12 insects.
Dust the prey insects with calcium (without D3) before each feeding. Switch to calcium + D3 once or twice per week, and use a multivitamin supplement two to three times per month. If using UVB lighting, reduce the frequency of D3 supplementation.
Addressing Anorexia
West African Fat-tails tend to become anorexic in response to environmental changes or during breeding season (especially males).
- First, check that temperature and humidity are appropriate.
- Check that shelters are adequately provided.
- Try changing the prey type (crickets to roaches or vice versa).
- If anorexia persists for more than two weeks with significant weight loss, consult a veterinarian.
Morph (Variety) Types
West African Fat-tail morphs are not as numerous as Leopard Gecko morphs, but have been increasing rapidly in recent years.
| Morph Name | Characteristics |
|---|
| Normal (Wild-type) | Brown striped pattern. Natural appearance. |
| White-out (WA) | Pale overall with faint striping. |
| Zero | Striping nearly absent, overall pale to light coloration. |
| Orb | Eyes completely white (also called Blue-eyed). Vision impact is debated. |
| Patternless | No striping, uniform coloration. Changes with growth. |
| Tangerine | Strong orange coloration. |
| Albino | Melanin deficiency. Characterized by red eyes. |
Combination morphs equivalent to Leopard Gecko "Super Maxsnow" also exist, and breeding is producing diverse combinations. Prices range from 5,000–15,000 yen for normal morphs, with rare combo morphs reaching 50,000 yen or more.
Breeding Methods
Breeding Age and Preparation
- Males: 12–18 months or older, weighing 60 g or more.
- Females: 18–24 months or older, weighing 80 g or more.
Females consume large amounts of calcium during egg production, so strengthen calcium and multivitamin supplementation for 2–3 months before breeding (conditioning). Avoid breeding individuals with poor body weight or health status.
Cooling (Brumation Preparation)
Mild temperature reduction (cooling) increases breeding motivation in West African Fat-tails.
- Gradually lower temperature during October to December (basking spot 27–28°C, cool zone 20–22°C).
- Reduce feeding amount by half.
- Maintain for 4–6 weeks, then gradually return to normal temperatures.
Provide water continuously during cooling. Individuals with uncertain health status can attempt breeding without cooling.
Pairing and Egg-laying
After cooling, house the male and female together (supervised cohabitation for approximately 1–2 hours is recommended). After confirming mating, separate the female and provide an egg-laying substrate (a nesting box filled with vermiculite or moist sphagnum moss).
Egg-laying Characteristics
- 1 clutch = 2 eggs (almost always 2 eggs)
- 3–5 clutches can be produced annually.
- Interval between clutches: 4–6 weeks.
Incubate laid eggs in a dedicated incubator at 28–30°C with 80–90% humidity. The incubation period is approximately 60–90 days.
Post-hatching Care
Wait 1–2 days after hatching before offering the first meal to hatchlings. Small crickets (1 cm or smaller) are ideal for the first feeding. Always provide shelters and wet hides.
Health Management and Important Points
Regular Checkup Items
- Shedding: Check for retained shed around the toes, tail, and eyes. If retained, carefully remove with a warm water soak.
- Body Weight: Measure and record weight monthly. Sudden weight loss is a sign of health problems.
- Feces: If no bowel movement for a week or more, constipation may be the cause. Check temperature and try a warm bath.
Common Diseases and Conditions
| Disease/Condition | Cause | Treatment |
|---|
| Improper Shedding | Insufficient humidity or nutrition | Warm bath + enhanced wet hide |
| Metabolic Bone Disease (MBD) | Calcium or D3 deficiency | Enhanced supplementation and UVB lighting |
| Cryptosporidiosis | Protozoan infection | Veterinary care (difficult to treat). Isolate individual. |
| Impaction | Accidental substrate ingestion | Veterinary care |
| Respiratory Infection | Low temperature and high humidity | Temperature adjustment and veterinary care |
Veterinarians experienced in treating West African Fat-tails can be found at animal hospitals specializing in exotic animals or those that handle reptiles. It is strongly recommended to research nearby compatible veterinary facilities before beginning care.
