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.
Show 4 more
  • 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 6 sq ft of floor · 35 x 24 x 18 in

Must be housed alone. Solitary; house singly

  • House one adult in a vivarium of at least 36 x 24 x 18 in, with a tight lid and good ventilation.
  • Provide a warm end with a basking surface around 86-91°F and a cool end of about 75°F, controlled by a thermostat, with a nighttime drop.
  • A low-output UVB tube supports bone health and is recommended.
Show 3 more
  • 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.

Care in depth

Diet

Insectivore (live insects)
  • 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

Signs of good health, and the common problems
  • 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 this urgent?

4 warning signs and how fast to act, 1 of them right away

Small geckos dehydrate and lose condition quickly. Weight is the fuel gauge, and in leopard and African fat-tailed geckos so is the tail.

Go now

Tremors, weak grip, or a jaw that will not close properlyGo now. Calcium and D3 deficiency.
Now

Today

Tail visibly thinning in a species that stores fat thereWeigh, then call with the trend. The fat store goes before the body condition does.
Today
Stuck 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.
Today
Refusing food with weight lossCheck the cool-end and warm-end temperatures, then call. A gecko that cannot reach its preferred temperature cannot digest.
Today

This 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.

Bedding and substrate

3 safe, 1 with a caveat, 3 to avoid

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.
safe
Coco fibre and orchid bark for tropical geckosHolds the humidity a crested or day gecko needs.
safe
Paper towelCorrect for quarantine, for hatchlings, and for any animal whose output you are watching.
safe

With a caveat

Sphagnum mossExcellent in a humid hide, poor as a whole-floor substrate: it stays wet.
with a caveat

Never

Calcium sandSold as digestible, which is exactly why it gets eaten. Implicated in impaction.
never
Crushed walnut shellSharp and indigestible.
never
Loose play sand alone for hatchlingsToo easy to swallow at that size.
never

Ground-dwelling geckos such as leopard and fat-tailed geckos need a humid hide whatever the main substrate is, and most of their stuck sheds trace back to its absence. Arboreal geckos get their shedding humidity from misting the whole enclosure, so stuck shed in them usually means the enclosure is too dry.

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

The recognised standards do not agree on this one
ReptiFiles: At least 36 x 18 x 18 in for one, larger strongly recommended; two of the three enclosures it lists are 36 x 24 in. The figure this site uses is that larger size, 36 x 24 x 18 in. Checked 2026-10-23.
Switzerland, Tierschutzverordnung: Not named. For nocturnal ground-dwelling geckos such as the leopard gecko: 6 x 6 head-body lengths of floor and 2 of height for up to two. Recorded for comparison: the law does not name this gecko, so it sets no minimum for it. Checked 2026-10-23.

That food is not on our list. Check which kind of gecko you have first (the two diets barely overlap), then ask an exotics vet.

Dust feeders with calcium to the schedule in the species guide, and keep a small dish of plain calcium available.
