African Fat-Tailed Gecko (Hemitheconyx caudicinctus) Care Sheet
The African Fat-Tailed Gecko is a small terrestrial gecko from West Africa, recognised by its heavy body, movable eyelids and thick tail used for storing energy reserves.
They are often compared with Leopard Geckos but should not simply be maintained under identical conditions. African Fat-Tailed Geckos naturally experience more humid environments and seasonal changes in moisture, while still requiring good ventilation and opportunities to choose between warmer, cooler, drier and more humid microclimates.
Generally calm but often somewhat shy, they can make rewarding captive reptiles when provided with suitable environmental conditions.

NATURAL HISTORY
African Fat-Tailed Geckos occur across parts of West Africa, from Senegal eastwards towards northern Cameroon.
They inhabit environments including:
- Sahel
- Dry savannah
- Moist savannah
- Dry forest
- Rocky areas
- Leaf-littered ground
Although their distribution includes relatively dry environments, they commonly make use of sheltered microhabitats beneath:
- Rocks
- Logs
- Leaf litter
- Crevices
- Burrows
These retreats can be considerably more humid and thermally stable than exposed surface conditions.
This is important when designing a captive enclosure: African Fat-Tailed Geckos should not simply be maintained either very dry like a desert species or constantly wet like a rainforest species.
ENCLOSURE
African Fat-Tailed Geckos are primarily terrestrial, so usable floor area is particularly important.
For a single adult, we recommend a minimum enclosure of approximately:
90 × 45 × 45 cm (36 × 18 × 18 in)
Larger accommodation is encouraged.
The enclosure should provide enough space for:
- A warm zone
- A cooler zone
- Multiple secure hides
- A humid retreat
- Digging opportunities
- Low-level climbing and exploration
Suitable enclosure types include:
- Glass terrariums
- PVC vivariums
- Wooden vivariums with appropriate sealing
- Other secure, well-ventilated reptile enclosures
The enclosure must be escape-proof.
HIDES
Provide at least:
- Warm-side hide
- Cool-side hide
- Humid hide
Additional hiding opportunities are strongly encouraged.
Suitable options include:
- Cork bark
- Rock-style hides
- Low caves
- Leaf litter
- Hollow cork
- Dense artificial or live planting
A gecko should never have to choose between feeling secure and maintaining an appropriate body temperature.
HUMID HIDE
A humid hide should be available consistently.
Unlike the older recommendation that the humid hide must always be the warmest hide, placing it towards the cooler or intermediate portion of the enclosure can provide a safer humid retreat without combining very high moisture with excessive heat.
Suitable moisture-retaining materials can include:
- Damp soil-based substrate
- Coco fibre
- Appropriate moisture-retaining substrate
The material should remain moist but should not become stagnant or waterlogged.
The humid hide assists with:
- Hydration
- Shedding
- Behavioural choice
It should not be the only source of environmental humidity.
SUBSTRATE
A naturalistic, diggable substrate is recommended for healthy established animals.
Suitable mixtures can contain:
- Organic topsoil
- Washed play sand
- Clay-containing components
- Leaf litter
There is no requirement for one exact 70/30 substrate recipe.
The aim is to create a substrate that:
- Holds some moisture
- Drains appropriately
- Allows digging
- Does not remain permanently saturated
- Resembles the firm soils encountered within natural habitats
Provide approximately:
10 cm (4 in) or more
where practical to allow natural digging behaviour.
Temporary Substrates
Paper towel can be useful during:
- Quarantine
- Veterinary treatment
- Faecal monitoring
Avoid
Avoid:
- Calcium sand
- Crushed walnut shell
- Cedar
- Highly aromatic wood shavings
- Sharp gravel
- Reptile carpet
Reptile carpet can trap claws and is difficult to maintain hygienically.
HEATING
African Fat-Tailed Geckos require a thermal gradient.
A suitable overhead daytime heat source can be used to recreate natural warming from above.
A halogen or appropriate incandescent basking lamp can provide:
- Visible light
- Infrared heat
- A natural daytime warming zone
Deep Heat Projectors may also have a role where non-visible supplementary heat is required.
Ceramic Heat Emitters are better regarded as supplementary ambient heaters rather than automatically being the primary daytime heat source.
TEMPERATURE
Warm Area / Warm Hide
Aim for approximately:
31–34°C (88–93°F)
during the warmer part of the year.
Cool Side
Approximately:
22–25°C (72–77°F)
Night
A natural nighttime reduction is appropriate.
Around:
20–23°C (68–73°F)
is suitable during routine warm-season husbandry.
Healthy adults can experience somewhat cooler seasonal conditions, but young animals should not be deliberately exposed to substantial cooling.
The animal must always be able to move freely between warmer and cooler locations.
SEASONAL TEMPERATURE VARIATION
African Fat-Tailed Geckos naturally experience seasonal changes.
Experienced keepers may reproduce a modest seasonal cycle, with:
- Warmer, more humid conditions during the wet season
- Cooler, somewhat drier conditions during the dry season
However, substantial deliberate cooling is not required for routine pet maintenance.
Young animals, unhealthy animals and underweight geckos should not be intentionally subjected to cool-season cycling.
HEATING SAFETY
All heating equipment capable of overheating the enclosure should be appropriately controlled.
Use:
- Suitable thermostat
- Digital thermometers
- Infrared temperature gun
Check temperatures at animal level.
Remember:
A thermostat controls the heater — it does not replace a thermometer.
All heat sources should be securely installed so the gecko cannot contact dangerously hot surfaces.
UVB & LIGHTING
African Fat-Tailed Geckos are primarily nocturnal, but this does not mean they receive no ultraviolet exposure.
Low-level UVB can be provided as part of high-quality captive husbandry.
A suitable linear low-output UVB system should be positioned over the warm portion of the enclosure.
Aim for approximately:
UVI 1.0–2.0 at the most exposed basking area
with a gradient towards:
UVI 0 in complete shade
Dense hides should allow complete withdrawal from UV exposure.
The correct lamp and installation distance depend on:
- Lamp model
- Reflector
- Mesh obstruction
- Distance from the animal
- Enclosure design
A suitable UV meter is the most reliable method of determining actual exposure.
PHOTOPERIOD
Provide a clear day/night cycle.
Approximately:
12 hours light / 12 hours darkness
provides a useful general schedule.
Seasonal variation can also be used, with slightly longer summer days and shorter winter days.
All visible and UV lighting should switch off overnight.
Do not use red, blue or purple night bulbs.
HUMIDITY
Humidity should fluctuate naturally rather than remaining at one constant high percentage.
African Fat-Tailed Geckos experience both wetter and drier periods in nature.
As a practical general guide:
Typical Daytime
Approximately:
50–70% relative humidity
Night
Humidity may naturally rise towards:
70–80%+
following misting or as temperatures fall.
During warmer/wetter seasonal conditions, humidity can be higher.
The enclosure should also contain a reliably humid retreat.
The goal is:
Moderate-to-high humidity + good ventilation + natural fluctuations
rather than a permanently saturated enclosure.
MISTING
Light misting can be used to reproduce natural humidity cycles.
Evening misting is particularly useful because humidity naturally tends to rise as temperatures fall.
The enclosure should not be continually sprayed to the point that:
- Substrate becomes waterlogged
- Surfaces remain permanently wet
- Airflow becomes stagnant
Monitor conditions and adjust misting according to the enclosure and room environment rather than following one fixed universal schedule.
WATER
Fresh drinking water should always be available.
Provide a shallow, stable water dish that is:
- Easy to access
- Difficult to overturn
- Cleaned regularly
- Refilled with fresh water
African Fat-Tailed Geckos may also lick moisture droplets following misting.
Routine soaking is unnecessary for a healthy animal.
DIET
African Fat-Tailed Geckos are insectivorous.
A varied diet of appropriately sized captive-bred feeder insects should be provided.
Suitable feeders include:
- Crickets
- Locusts
- Dubia roaches
- Other appropriate roaches
- Black soldier fly larvae
- Silkworms
- Mealworms
- Other suitable feeder invertebrates
Higher-fat feeders such as waxworms should be offered sparingly.
Variety is preferable to relying on one feeder species.
FEEDER SIZE
Prey should be appropriately sized for the individual animal.
The commonly used guideline of insects approximately no wider than the space between the gecko’s eyes can be useful, particularly for juveniles.
However, prey size should ultimately be based on the gecko’s ability to capture and swallow it comfortably.
FEEDING FREQUENCY
Feeding frequency depends on:
- Age
- Size
- Growth rate
- Activity
- Reproductive status
- Prey size
- Body condition
As a general guide:
Hatchlings & young juveniles: Small meals daily or near-daily.
Older juveniles: Approximately every 1–2 days.
Adults: Commonly every 3–5 days depending on body condition and meal size.
These are guidelines rather than rigid rules.
An adult with very large fat reserves may require less frequent feeding.
BODY CONDITION & THE TAIL
African Fat-Tailed Geckos store substantial energy reserves within the tail.
A healthy tail should appear:
- Thick
- Well rounded
- Proportionate to the body
However, an extremely enlarged tail should not automatically be interpreted as ideal health.
Body condition should be assessed using the entire animal, including:
- Tail
- Abdomen
- Limbs
- Neck
- Overall muscle condition
Unexpected loss of tail thickness can be an important early sign of weight loss or illness.
CALCIUM & SUPPLEMENTATION
Captive feeder insects should receive appropriate supplementation.
A suitable regime should provide:
- Calcium
- Vitamin D3 where appropriate
- Vitamin A
- Other essential vitamins and minerals
There is no universal requirement to dust every meal with calcium regardless of the product being used.
Supplementation depends on:
- Product formulation
- Feeding frequency
- Age
- Reproductive status
- UVB provision
- Overall diet
Follow the manufacturer’s instructions for the supplement being used.
Where effective UVB is provided, excessive dietary vitamin D3 supplementation should be avoided.
GUT LOADING
Feeder insects should themselves be fed an appropriate nutritious diet before being offered.
Suitable gut-loading foods may include:
- Leafy greens
- Vegetables
- Appropriate commercial insect diets
Gut loading should be part of normal feeder management rather than something performed for only a few hours immediately before feeding.
A healthy feeder insect generally provides better nutrition than one kept on a nutritionally poor diet.
HANDLING
African Fat-Tailed Geckos are generally calm but can be shy.
Newly acquired animals should be allowed time to settle before regular handling begins.
When handling:
- Approach calmly
- Scoop the gecko from underneath
- Support the entire body
- Keep it relatively close to a safe surface
- Avoid restraining it unnecessarily
Short, calm sessions are preferable.
Handling is usually best carried out during the evening when the animal would naturally be more active.
TAIL WAVING
African Fat-Tailed Geckos may slowly wave or raise their tail when:
- Alarmed
- Defensive
- Stressed
- Investigating a perceived threat
This should not automatically be interpreted as playful or curious behaviour.
If a gecko displays repeated defensive tail movements, reduce disturbance and allow it to retreat.
TAIL LOSS
Like many geckos, African Fat-Tailed Geckos can voluntarily detach the tail as a defensive response.
This is known as caudal autotomy.
The tail can regenerate, but the replacement differs in appearance from the original.
Never:
- Grab the tail
- Lift the gecko by the tail
- Deliberately encourage tail loss
A gecko that has lost its tail should be monitored carefully while it heals.
Veterinary advice should be sought if the site becomes:
- Swollen
- Discoloured
- Excessively inflamed
- Abnormally discharged
SOCIAL HOUSING
African Fat-Tailed Geckos are best housed individually.
They do not require another gecko for companionship.
Cohabitation can result in:
- Aggression
- Competition for hides
- Competition for heat
- Feeding suppression
- Injury
- Chronic stress
- Unplanned breeding
Adult males must not be housed together.
Although compatible pairs may sometimes be maintained by experienced keepers, this should not be treated as the default arrangement for pet animals.
Individual housing allows much more accurate monitoring of:
- Food intake
- Faeces
- Weight
- Shedding
- Health
SEXING
Mature males generally show:
- Distinct pre-anal pores
- Hemipenal bulges behind the vent
Females lack pronounced hemipenal bulges and generally have less prominent pores.
Young juveniles may be difficult to sex accurately.
SHEDDING
Healthy African Fat-Tailed Geckos periodically shed their skin and commonly consume the shed.
This is normal behaviour.
Appropriate hydration and access to a humid hide support successful shedding.
After shedding, check carefully around:
- Toes
- Feet
- Tail tip
- Eyes
Persistent retained skin around toes can restrict circulation.
Repeated shedding difficulty should prompt assessment of:
- Humidity
- Hydration
- Temperature
- Nutrition
- Overall health
ENRICHMENT
African Fat-Tailed Geckos benefit from a complex enclosure.
Useful enrichment includes:
- Deep substrate
- Leaf litter
- Cork
- Low rocks
- Secure branches
- Multiple hides
- Different surface textures
- Low ledges
- Live or artificial plants
- Naturalistic feeding opportunities
Although primarily terrestrial, they can climb low structures and should not be maintained in completely flat, empty enclosures.
CLEANING & HYGIENE
Remove:
- Faeces
- Urates
- Dead feeder insects
- Contaminated substrate
promptly.
Water dishes should be cleaned regularly.
Naturalistic and bioactive enclosures still require observation and maintenance.
Always wash your hands thoroughly after handling:
- The gecko
- Feeder insects
- Waste
- Enclosure equipment
Reptiles can carry Salmonella without appearing ill.
QUARANTINE
New reptiles should ideally undergo an appropriate quarantine period before introduction to an established collection.
During quarantine monitor:
- Appetite
- Weight
- Faeces
- Shedding
- Hydration
- General behaviour
Veterinary examination and faecal parasite testing may be appropriate, particularly when the animal’s previous history is uncertain.
Paper towel or another easily monitored temporary substrate can be particularly useful during quarantine.
HEALTH
Potential warning signs include:
- Persistent refusal to feed
- Unexplained weight loss
- Rapid reduction in tail condition
- Swollen or deformed limbs
- Weakness
- Tremors
- Soft or abnormal jaw
- Difficulty walking
- Persistent retained shed
- Eye problems
- Skin lesions
- Regurgitation
- Abnormal faeces
- Persistent diarrhoea
- Swelling
- Abnormal breathing
- Significant behavioural changes
Metabolic Bone Disease
Inadequate calcium, vitamin D3 and/or UVB provision can contribute to metabolic bone disease.
Possible signs include:
- Weakness
- Tremors
- Skeletal deformity
- Swollen limbs
- Difficulty walking
- Softened jaw
Correct lighting, heating and nutrition are fundamental to prevention.
If illness is suspected, consult a suitably experienced reptile or exotic veterinarian.
LONG-TERM CONSIDERATIONS
African Fat-Tailed Geckos can live for 15–20 years or longer.
Before acquiring one, consider the continuing cost of:
- Adult enclosure
- Heating
- UVB
- Replacement lamps
- Thermostatic control
- Substrate
- Live feeder insects
- Supplements
- Veterinary treatment
They are often described as an alternative to a Leopard Gecko, but they should not simply be kept using identical husbandry.
Providing appropriate humidity cycles, secure retreats, deep substrate and environmental choice is particularly important for long-term success.
