Overview
What is this animal?
- The African fat-tailed gecko is a ground-dwelling, nocturnal relative of the leopard gecko from the savannahs and dry forests of West Africa.
- Like the leopard gecko it has eyelids and lacks climbing pads, storing fat in its thick tail, but it comes from a more humid habitat and is often considered even calmer.
- It is a hardy, slow-moving and forgiving first reptile that lives well into its teens.
- Its modest size and gentle temperament suit beginners, provided they meet its need for a warm spot, a humid hide and a properly furnished terrestrial vivarium.
Temperament
- African fat-tailed geckos are typically docile, even more placid than leopard geckos, and tolerate gentle, regular handling once settled.
- They are nocturnal, so they are quiet by day and most active in the evening.
- When startled they may wave the tail or vocalise, but they rarely bite.
- They are solitary and should be housed alone.
- Males fight, and any grouping risks stress, injury and food competition.
- One gecko per enclosure is the correct and trouble-free approach for this species.
A good fit for
- First-time reptile keepers
- People wanting a very calm ground gecko
- Keepers with limited space
- Those who can commit 15+ years
Common mistakes to avoid
- Humidity too low, causing stuck shed
- Loose sand substrate contributing to impaction
- Skipping calcium and UVB
- Housing two together, causing fights
Enclosure
Minimum 4,050 cm² of floor (628 sq in) · 90 × 45 × 45 cm
Must be housed alone. Solitary; house singly
- House one adult in a vivarium of at least 90x45cm floor area, with a tight lid and good ventilation.
- Provide a warm end with a basking surface around 30-33C and a cool end of about 24C, controlled by a thermostat, with a nighttime drop.
- A low-output UVB tube supports bone health and is recommended.
- Offer at least three hides, including a humid hide with damp moss, as this species needs higher humidity (around 50-60%) than leopard geckos to shed cleanly.
- Use a solid or fine, particle-free substrate such as a bioactive soil mix or tile rather than deep loose sand, which can contribute to impaction.
- Spot-clean daily.

Diet
- African fat-tailed geckos are strict insectivores.
- Feed a varied rotation of appropriately sized live insects such as crickets, dubia roaches, locusts and black soldier fly larvae, keeping fatty waxworms as an occasional treat only.
- Gut-load all feeders and dust them with calcium and a vitamin/D3 supplement on a regular schedule.
- Feed juveniles daily and adults every two to three days, with prey no longer than the gap between the eyes.
- Provide a shallow dish of fresh water at all times.
- Obesity from over-feeding rich insects and metabolic bone disease from poor supplementation are the most common diet-related issues.
Health
- A healthy fat-tailed gecko has a plump tail, clear eyes and a steady appetite.
- Because it needs more moisture, retained shed around the toes and eyes is a frequent problem if humidity is too low, so a damp hide and correct husbandry are essential.
- A dropped tail will regrow with an altered shape and colour.
- Watch for metabolic bone disease, impaction and respiratory infections from cold or overly damp, poorly ventilated conditions.
- A wobbly gait, soft jaw or weight loss needs a vet experienced with exotics.
- Stable warmth, correct humidity and good supplementation prevent most problems.
Is your enclosure big enough?

Is this urgent?
Small geckos dehydrate and lose condition quickly, and the tail is the fuel gauge.

Tail visibly thinning in a species that stores fat thereWeigh, then call with the trend. The fat store goes before the body condition does.
TodayStuck shed around the toes or over the eyesRaise humidity, offer a damp hide, and call if it is not clear within a day. Constricting shed rings cost toes. This is the most common avoidable injury in geckos.
TodayRefusing food with weight lossCheck the cool-end and warm-end temperatures, then call. A gecko that cannot reach its preferred temperature cannot digest.
TodayThis is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a african fat-tailed gecko eat that?
Geckos split into two diets that share almost nothing: insectivores like the leopard gecko, and the fruit-and-insect species like the crested gecko. Check which one you have.

Black soldier fly larvaeHigh in calcium, and readily taken. Several per feed.

Dust feeders with calcium to the schedule in the species guide, and keep a small dish of plain calcium available for insectivorous species.
What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
Bedding and substrate
Match the substrate to the species' humidity, and never let a small gecko stand on anything it can swallow whole.
Safe
Topsoil and play sand mix for arid geckosPacks firm, holds a burrow, and is what a leopard gecko would actually stand on.
safeCoco fibre and orchid bark for tropical geckosHolds the humidity a crested or day gecko needs.
safePaper towelCorrect for quarantine, for hatchlings, and for any animal whose output you are watching.
safeWith a caveat
Sphagnum mossExcellent in a humid hide, poor as a whole-floor substrate — it stays wet.
with a caveatNever
Calcium sandSold as digestible, which is exactly why it gets eaten. Implicated in impaction.
neverCrushed walnut shellSharp and indigestible.
neverLoose play sand alone for hatchlingsToo easy to swallow at that size.
neverA humid hide is not optional for most geckos, whatever the main substrate is. Most stuck-shed problems trace back to its absence.
