The African fat tailed gecko is a stocky, big eyed lizard. It is best known for the swollen, fat filled tail that gives it its name. It comes from the dry savannas and rocky woodlands of West Africa.

It spends the day hidden. It comes out after dark to hunt insects. Among pet geckos it sits close to the leopard gecko in size, temperament and care.

This guide covers where the species comes from and what it needs in captivity. It also covers what to expect if you bring one home, and how it compares with other geckos in the hobby.

Fat Tailed Gecko Care Overview

Caring for a fat tailed gecko means giving it a warm, humid hide inside an otherwise moderate, fairly dry tank. It needs a proper thermal gradient, a humid retreat and a steady diet of gut loaded insects.

Handling should stay brief and gentle, especially in the first weeks after bringing a gecko home. Let a new arrival settle into its enclosure for several days before any handling at all. Rushing this step is a common source of stress and tail loss in new pets.

Most of the husbandry overlaps with leopard gecko care. Both belong to the eyelid gecko family Eublepharidae. Fat tails tolerate, and often prefer, slightly higher humidity than leopard geckos.

New keepers should check temperatures with a real thermometer, not by feel. Keep a humid hide filled with damp sphagnum moss or coco fiber. Skipping the humid hide is the most common reason a fat tail gecko struggles to shed.

Enclosure Setup

A single adult fat tailed gecko does well in a 20 gallon long tank. Floor space matters more than height, since this is a ground dwelling species. Juveniles can start smaller.

Keepers commonly move juveniles up well before adulthood to avoid repeated moves. Substrate choice divides keepers. Paper towel, reptile carpet or plain tile is the safest option for young or underweight animals.

These flat substrates remove any impaction risk from swallowed material. Many experienced keepers later move adults onto a bioactive mix of coco fiber, topsoil and leaf litter. This works once the animal is feeding well and gaining weight steadily.

Loose, fine sand is best avoided, especially for juveniles. Accidental ingestion during feeding has been linked to gut blockages in eublepharid geckos. It is not worth the risk.

Furnish the tank with at least two hides: one on the warm side, one on the cool side. Add the humid hide already mentioned, plus a water dish. A few climbing branches or cork bark give extra cover, as they might for a gargoyle gecko setup.

Full setup guidance, including specific products and layout ideas, lives in the site’s housing guide.

This species has no toe pads. It cannot climb glass the way a crested gecko or tokay gecko can. Still, use a secure, well ventilated lid, since a determined gecko can push against a loose screen.

Heating and Lighting

Fat tailed geckos need a clear thermal gradient, not one flat temperature. A warm side floor temperature of roughly 88 to 92F helps the gecko digest food properly. A cool side of 75 to 80F gives it somewhere to retreat.

Animal Diversity Web, a research database run by the University of Michigan Museum of Zoology, notes that wild fat tailed geckos favor the 80 to 90F range. They also need moderate humidity to shed well. That figure lines up with the gradient keepers use in captivity.

An under tank heater on the warm side, controlled by a thermostat, is the standard setup. Overhead ceramic heat emitters work too. A thermostat should always prevent temperature spikes.

This species is strictly nocturnal. It does not bask under bright light the way a bearded dragon does. Many keepers still offer a low output UVB bulb, such as the Arcadia ShadeDweller ProT5 Kit 7%, since modest UVB can support vitamin D3 alongside a dusted diet.

A humid hide with damp moss or coco fiber keeps local humidity high near the warm side. This one addition solves most of the shedding problems new keepers run into.

What Fat Tailed Geckos Eat

The African fat tailed gecko is an insectivore that hunts live prey after dark. Crickets are the classic staple. Most keepers also rotate in mealworms, dubia roaches, black soldier fly larvae and occasional waxworms or hornworms.

Animal Diversity Web lists crickets, mealworms, waxworms and hornworms as typical captive food. Insects should be gut loaded with a nutritious feeder diet first. Do this for a day or two before offering them.

Dust feeder insects with a calcium supplement at most feedings. Use a calcium supplement with vitamin D3, such as the Zoo Med Repti Calcium with D3, a couple of times a week unless the gecko already gets UVB. Juveniles and gravid females need calcium most consistently.

Low calcium intake is a direct path to metabolic bone disease. Feed juveniles daily or every other day. Feed adults two to three times a week, keeping portions modest.

A fresh, shallow water dish should always be available. Most hydration still comes from prey and the humid microclimate. One quirk of the species is that it will often eat its own shed skin, which is normal.

For broader feeder rotation ideas and gut loading tips, see the site’s feeding guide.

Health and Common Problems

Most fat tailed gecko health problems trace back to husbandry gaps, not infectious disease. Low humidity leads to retained shed, especially around the toes and tail tip. Retained shed can cut off circulation if it is not gently soaked off.

Loose or gritty substrate raises the risk of impaction, especially in young or underweight animals. Signs include reduced appetite, a swollen belly or a lack of droppings. Switching to paper towel while an animal is thin removes most of this risk.

Metabolic bone disease is the other major concern. It comes from chronically low calcium or vitamin D3. Early signs include a soft jaw, a wobbly gait or bent limbs, and it needs a reptile veterinarian.

The tail itself is a useful health indicator. A thin, shrunken tail usually means the gecko has been eating too little. Tail loss from rough handling is stressful but rarely dangerous, since the tail regrows over several weeks.

Reptiles, including geckos, can carry Salmonella even when they look healthy, according to the CDC. Wash your hands after handling the gecko, its enclosure or feeder insects. Keep tanks and supplies away from kitchen counters and food prep areas.

See a reptile veterinarian promptly if a gecko stops eating for more than a couple of weeks. The same goes for open mouth breathing, swelling, discharge or sores. Small geckos decline quickly, so early attention matters.

The site’s health guide covers general reptile warning signs in more depth. A quarantine period for any new gecko, away from other reptiles in the home, also lowers the risk of spreading illness.

Behavior and Temperament

Fat tailed geckos are calm, ground dwelling animals. They spend daylight hours tucked into a hide and become active after dark. Once settled into a stable enclosure, most individuals tolerate gentle, brief handling reasonably well, as covered in our fat tailed gecko behavior guide.

The species is largely solitary and can be territorial, particularly among males. Most keepers house adults singly, or as a single male with one or more females. Males in close contact sometimes fight, so watch any pairing closely.

Vocal behavior is one of the more distinctive traits of this species. Fat tailed geckos can produce quiet squeaks or clicking sounds. This usually happens during territorial disputes or when the gecko is startled.

Like many eublepharid geckos, this species can drop its tail if grabbed or badly frightened. This defense is called autotomy, and it lets the gecko escape a predator’s grip. A dropped tail regrows, but it rarely matches the original in shape.

Watch for stress signs such as hiding constantly even at night, a darker color and refusal to eat. Tail waving often comes before a defensive bite or a dropped tail. Most of these signs settle once temperature, humidity and hides are corrected.

Breeding

Breeding fat tailed geckos follows a pattern similar to leopard gecko reproduction. Both are oviparous eublepharids with temperature dependent sex determination. Incubation temperature, not genetics, decides the sex of the hatchlings.

In the wild, breeding activity concentrates from roughly November through March, per Animal Diversity Web. Females lay one to three eggs per clutch. They may produce up to five clutches across a season when conditions support it.

Incubation takes roughly six to twelve weeks, depending on temperature. Warmer incubation generally speeds development. Breeders typically use a dedicated incubator rather than leaving eggs in the main enclosure.

Breeding should only involve healthy, well fed adults at a mature size. Underweight females face a higher risk of egg binding. A nesting box with moist substrate gives a gravid female somewhere to dig and lay.

Hatchlings reach sexual maturity at roughly eight to eleven months old under good conditions. A female kept without a male may still lay infertile eggs from time to time. This is normal reproductive behavior, not a health problem.

Lifespan and Size

Adult fat tailed geckos reach about 8 inches in total length. They weigh between 40 and 90 grams, with most healthy adults settling around 50 to 75 grams. Females tend to run slightly smaller than males.

Lifespan is one of this species’ strongest selling points among small pet lizards. With consistent care, captive fat tailed geckos commonly live 10 to 20 years. Animal Diversity Web notes that some captive individuals may live even longer.

Wild lifespan is harder to pin down. Researchers estimate something in the range of 10 to 15 years, though wild population data stays limited. Captive animals live longer, largely because they face fewer predators and food shortages.

A thick, well proportioned tail is a useful health signal throughout life. A tail noticeably thinner than the base of the body usually points to a feeding problem, not just a small size.

Cost of Keeping a Fat Tailed Gecko

A captive bred fat tailed gecko typically costs between 40 and 150 dollars. Price depends on morph, age and breeder reputation. Unusual or newer color forms tend to cost more.

Setup costs matter more than the gecko itself. A properly sized enclosure, thermostat, heater, hides, substrate and a basic UVB fixture typically run 150 to 300 dollars for a first setup. Buying secondhand gear can lower that number.

Ongoing costs stay modest. Feeder insects, calcium and vitamin supplements, and the occasional bulb replacement add up to a small monthly expense once the setup is in place.

The biggest budget item new keepers underestimate is veterinary care. This species can live 10 to 20 years. It is worth locating a reptile experienced veterinarian before an emergency happens.

Buying the right sized enclosure the first time, rather than upgrading twice, tends to save money over the life of the pet. A well built setup also needs fewer repairs and replacement parts down the line.

Fat Tailed Gecko Morphs and Color Forms

Decades of captive breeding have produced color and pattern forms beyond the wild type banded look. Common examples include tangerine animals with strong orange tones and striped individuals with a bold pale dorsal line. Patternless or ghost type geckos, with reduced markings, are also common.

Breeders have also produced lighter, high contrast forms, sometimes marketed as caramel or white and yellow. Naming is far less standardized than in leopard geckos. Morph inheritance here is tracked mainly through breeder records rather than formal genetic studies.

Morphs do not generally change care requirements. Temperature, humidity, diet and enclosure needs stay the same regardless of color form. Choosing a morph mostly comes down to personal preference and budget.

Frequently Asked Questions

Are fat tailed geckos good for beginners?

Yes. Their husbandry closely resembles the leopard gecko. They tolerate normal household temperatures with basic heating gear, and they generally handle calmly once settled.

How big do fat tailed geckos get?

Adults reach roughly 8 inches long and weigh between 40 and 90 grams. Growth slows once a gecko reaches sexual maturity around 8 to 11 months old.

Do fat tailed geckos need UVB?

They are nocturnal and do not bask, but many keepers still provide a low output UVB bulb. It supplements dietary vitamin D3. It is not strictly mandatory with proper calcium and D3 dusting, but it is good practice.

What is the difference between a fat tailed gecko and a leopard gecko?

Both are ground dwelling eublepharid geckos with similar care. The fat tail gecko usually shows a plainer banded pattern and prefers slightly higher humidity. It also has a noticeably thicker, more uniform tail than a crested gecko or leopard gecko.

How long do fat tailed geckos live?

With consistent care, 10 to 20 years is typical in captivity. That makes this one of the longer lived small pet lizards. Wild lifespan is estimated lower, around 10 to 15 years.

Can fat tailed geckos live together?

Adult males are territorial and should not be housed together. A single male with one or more females can work. Any pairing should still be watched closely for stress or aggression.
