Welcome to the ultimate guide for African Fat-Tailed Gecko (AFT) care! This comprehensive resource is crafted by reptile husbandry experts, drawing upon scientific research, natural history, and the extensive experience of dedicated keepers and breeders.
African fat-tailed geckos are becoming an increasingly popular pet, in part because of their ability to thrive in captivity but also because of their docile dispositions and their openness for being handled. Their normal coloring consists of a pale tan or brown background that is accented by bold brown and tan stripes, with some also displaying a thin white stripe along their back.
This care sheet is a simplified care summary, not a full ReptiFiles care guide. While I have done my best to ensure that the information contained is accurate, due to time constraints, the research behind ReptiFiles care sheets is not as thorough as the research involved with my full-length care guides.

Appearance and Characteristics
African fat-tailed geckos are 8-10″ lizards with soft, almost “pudgy” appearance: a long, stout body, stubby limbs, an oval head, pebbled skin, and a plump, segmented tail. Their coloring features alternating bands of medium and dark brown, sometimes with dark spots and white markings, including a white stripe from head to tail. Although they are geckos, they are unique from most others in that they have eyelids and can’t walk up walls.

Natural Habitat
African fat-tailed geckos are native to West Africa, ranging from Senegal to northern Cameroon. They prefer dry Sahel and dry/moist savannah for habitat, and are generally found near rock crevices and among the leaf litter of dry forests.
Temperament and Handleability
African-fat tailed geckos generally have very docile, tolerant dispositions and can make very handleable pet lizards. Handleability Score: 4 out of 5: Good Handleability. African fat-tailed geckos are fairly tolerant of humans and can be great to handle. However, they’re generally asleep during the day when humans are active.
African fat-tailed geckos can be shy, but can also be open to being handled and can become tame with regular contact. It is important to always take great care when handling a gecko and it is important to never hold or constrain a gecko by its tail. The tail of a fat-tailed gecko will detach as part of a defense mechanism called caudal autotomy.
Enclosure
African fat-tailed geckos need at least a 36″x18″x16″ enclosure, preferably larger. Reptiles aren’t like dogs and cats that can simply roam around your house. They are very sensitive to their environment, and need their own enclosure set up according to their specific needs.
Enclosure Size Requirements
African fat-tailed geckos should be housed in an enclosure that is no smaller than 36″L x 18″W x 16″H. A common available terrarium size is a 40 gallon long. This is the bare minimum, calculated according to the reptile’s average length and activity patterns.

However, if you can provide an enclosure with more floor space, do it! Housing your gecko in a larger enclosure will encourage it to be more active and demonstrate more natural behaviors. We recommend front-opening enclosures for easier access and security.
Here are some enclosures that are appropriate for housing African fat-tailed geckos:
- Kages 36″x24″x18″ PVC Reptile Enclosure
- Toad Ranch SF36 3’x2’x19 Luxury Reptile Enclosure
- Repti Zoo 36″ x 18″ x 18″ Reptile Terrarium
Can multiple African fat-tailed geckos be housed in the same enclosure? No, we do not recommend cohabitation for pet African fat-tailed geckos. This species is generally considered to be solitary, and does not appear to live in groups in the wild. Seufer et al. notes that a pair can be successfully housed together in a large enough enclosure, but keep in mind that if the geckos don’t get along, they can fight and severely injure one another. Males in particular are known to fight.

Substrate
Loose, naturalistic substrate is the best kind of substrate for housing African fat-tailed geckos. Substrate should be 3-6″ deep to facilitate natural burrowing behavior. The best way to recreate an AFT's natural habitat of packed sandy loam is with a DIY mix of roughly 70% untreated topsoil + 30% play sand. Topsoil must not contain any fertilizers, manure, or perlite/vermiculite - read the ingredients! Mix well, soak until muddy, then pack it firmly at the bottom of the enclosure. Make sure it is 100% dry before introducing the gecko to the setup.
You can also use a pre-packaged substrate, though this is more costly than DIY. Depending on the brand, you may still need to add some topsoil (if too dusty) or sand (if too dense/moist) to reach desired consistency. Here are some recommended commercial substrates appropriate for African fat-tailed geckos:

- DIY semi-arid mix: 40% organic topsoil, 40% play sand, 20% Zoo Med Excavator Clay
- Lugarti Natural Reptile Bedding
- Zoo Med ReptiSand
- Exo Terra Desert/Riverbed Sand
- Exo Terra Stone Desert
Bioactive Substrate
Another option is a bioactive setup. Bioactive enclosure setups are designed to mimic a reptile’s natural environment and stimulate natural behaviors. All above substrates can easily support bioactivity with the addition of leaf litter and a “cleanup crew” of isopods and springtails that clean up uneaten food and fecal remains, making bioactive substrates incredibly low maintenance.
Unsafe Substrates
These substrates are particularly dangerous to African fat-tailed geckos because they pose major health risks. Avoid the following substrates at all costs and stick to the list in the previous section.
- Reptile carpet - harbors bacteria, can injure & rip out teeth/claws
- Shelf liner - produces dangerous VOCs (volatile organic compounds)
- Linoleum - produces dangerous VOCs (volatile organic compounds)
- Calcium sand - severe impaction risk due to presence of calcium carbonate
- 100% play sand - doesn't hold humidity or support burrows
- Wood shavings, chips, or bark - causes impaction & discomfort
- Coconut fiber - dusty when dry, humid when wet, higher risk of respiratory issues
- Ground walnut shell - dusty, dangerously sharp, & risk of severe impaction
Quarantine Substrate
When you first bring your new African fat-tailed gecko home, you will need to quarantine for at least 1 month. This means keeping the enclosure as sterile as possible and closely monitoring the gecko's health. Paper towels or Komodo Repti-Pads are the best substrate for quarantine, as they can be frequently replaced and make it easier to observe feces and other potential health issues. Paper towels or pads should be fully replaced at least once a week and any soiled areas must be replaced daily.
Environmental Enrichment
Reptiles are much more intelligent than we humans tend to give them credit for, and that means they need things to entertain them. Otherwise they exist in a state of perpetual boredom, which makes them dull, inactive, and overall less interesting as pets. When reptiles have objects to interact with in their enclosure, they become less stressed and more engaged with their environment. This practice is called environmental enrichment.
It’s important to choose enrichment items (a.k.a. enclosure décor) that are appropriate to your pet’s natural behaviors. Here are some other objects that serve a vital function in a African fat-tailed gecko terrarium:
- Hides: An African fat-tailed gecko needs at least three hides: a warm dry hide below the heat source, a cool dry hide on the opposite side, and a humid hide in between, slightly closer to the warm side to avoid a cold, wet environment. The humid hide should be filled with coconut fiber or sphagnum moss and kept at 70-80% humidity at all times, using a hand mister. All 3 of the required hides should be dark, snug, & fully enclosed with a single entrance.
- Rocks/Slate: One of the best ways to provide a naturalistic basking area and attractive appearance is with rocks. African fat-tailed geckos like climbing, and in fact, stacking pieces of slate with 1-2” spacers in-between simulates the cracks that they utilize in their natural environment. You can even build a warm hide with slate or flat rocks to double as a basking spot on top and a cozy cave underneath!
- Climbing Objects: Branches, logs, and cork bark are excellent for varying the terrain and giving your AFT things to climb on/in.
- Plants: Plants are a great way to add more coverage and enhance the appearance of a naturalistic enclosure! Make sure to wash artificial plants before using. Any live plants should be nontoxic and suited to a dry environment.
- Calcium Dish: Geckos should have access to a small dish or bottle cap of calcium without D3 that they can lick, allowing them to self-regulate their calcium intake between feedings, if needed.
- Backdrop: If you’re using an all-glass enclosure, adding a naturalistic backdrop can be much more attractive. Blocking 3 sides of the enclosure also helps the gecko feel more secure in its environment.
Without décor, your gecko’s terrarium is just an expensive box of dirt. Hollow logs, thick branches, leaf litter, ledges, and artificial or drought-resistant live plants work well as décor in an African fat-tailed gecko terrarium. You can also provide additional hideouts.
How do I keep my enclosure clean?
To control the growth of pathogens and keep your African fat-tailed gecko’s enclosure hygienic and odor-free, it’s important to clean it regularly.
Non-Bioactive Enclosures: Spot-cleaning should be performed daily. This is the routine removal of uneaten food, feces, urates, and contaminated substrate. Soiled surfaces, food dishes, and water dishes should be scrubbed with reptile-safe disinfectant and rinsed at least weekly. Substrate should be completely removed and replaced every 4-6 months, depending on how diligent you are about spot-cleaning. This is also a good time to completely disinfect the enclosure with an animal-safe disinfectant like F10SC or chlorhexidine.
Bioactive Enclosures: If you have a bioactive enclosure, “cleaning” will be more like periodic maintenance: watering the plants, adding biodegradables, and feeding the CUC as needed. Substrate does not need to be replaced. Some spot-cleaning will still be required for urates and soiled surfaces.
Lighting, Temperature and Humidity
African fat-tailed geckos are nocturnal, which means that they are primarily active at night. This means that they are likely to prefer cooler temperatures, are exposed to low levels of indirect UVB during the day, and have exceptional night vision. All lights should be turned off at night. You can use a 12/12 day/night cycle, or you can vary day length seasonally to encourage more natural hormonal rhythms. If you choose to do the latter, lights should be on for up to 13 hours/day during summer, and down to 11 hours/day during winter, with gradual increments in-between.
A heat lamp (required) and a UVB lamp (strongly recommended). UVB is important for healthy metabolism, specifically vitamin D synthesis and calcium metabolism, improving skin health, and strengthening the immune system. UVA is beneficial to eyesight and is sensed by their pineal gland to regulate a circadian rhythm. Infrared radiation (i.e. heat) is important for reptiles' thermoregulation. As ectotherms, they rely on the heat of the sun to warm their bodies and stimulate their metabolism, digest their food, and stay alert and active.
All light and heat should be kept on a regular schedule using outlet timers or done manually. This allows for a predictable day/night cycle which the gecko can follow, allowing for natural hormonal rhythms and good mental health. We recommend the following schedule for African fat-tailed geckos, based on their natural environment:
UVB: African fat-tailed geckos benefit greatly from a UVB lamp in the enclosure. While they are technically capable of surviving without UVB if they receive sufficient supplementary vitamin D3 in their diet, simply surviving is not thriving, so we strongly recommend providing appropriate UVB. D3 supplement dosing is very imprecise and not efficiently absorbed by the body. Experts don't know exactly how much vitamin D3 fat-tailed geckos need, but we do know how much UVB they need for to self-regulate their own internal D3 production, so providing a UV lamp is far more natural and beneficial to promote optimum health.
Most African fat-tailed geckos do best with a 5-7% UVB output T5 lamp. Albinos and other less-pigmented morphs (amel, caramel, ghost) are more sensitive to UVB and may benefit from a lower output lamp, like a 2-3% output T5 or 5-7% output T8. 5-7% T5 bulbs are still safe for UVB-sensitive morphs, as long as plenty of shady coverage is provided throughout the enclosure.
We recommend Arcadia or Zoo Med linear fluorescent bulbs, as these brands produce the best and most reliable UVB lamps on the market. The lamp should be roughly ⅓ - ½ the width of the enclosure and placed on the same side as the heat lamp. So if your enclosure is 36”, your bulb should be 12-18” long. For a 4’ enclosure, a 22” bulb is best. Avoid “compact” and coil UVB bulbs, as these cannot properly distribute a UV gradient across the enclosure.
The strength of the UVB lamp’s output varies according to distance from the bulb - stronger when closer, and weaker when further away. If you are using a Solarmeter 6.5 to measure your UVB lamp’s output, the UVI (UV Index) reading should be between 1.0-2.0 at the height of the gecko’s back when standing on the basking platform (or 0.5-0.7 for albinos) and down to 0 on the cool side.
Temperature
Humans are warm-blooded, which means that our body temperature is automatically regulated. African fat-tailed geckos, however, are cold-blooded, which means that they have to move between areas of different temperatures to regulate their body temperature. In the wild, African fat-tailed geckos warm up during the day by sleeping in a warm burrow or patch of sunlight. In captivity, the best way to replicate the warming effects of sunlight is with a heat lamp, possibly supplemented (but not replaced) by a heat mat.
Here are the recommended temperature ranges for African Fat-Tailed Geckos:
RAINY/WARM SEASON (April-October)
- Warm hide: 90-94°F (32-34°C)
- Cool side: 72-77°F (22-25°C)
- Nighttime: 72-77°F (22-25°C)
DRY/COOL SEASON (November-March)
- Warm hide: 79°F (26°C)
- Cool side: 68-74°F (20-23°C)
- Nighttime: 63-64°F (17-18°C)
Generally speaking, a ~50w PAR30 halogen heat bulb or two should be plenty for achieving the desired temperatures in your African fat-tailed gecko terrarium. However, if the bulb is mounted inside the enclosure, a halogen bulb is likely to be too intense and I recommend an incandescent spot bulb instead, such as the Exo Terra Intense Basking Spot or ReptiZoo Intense Basking Spot.
Place one of the hides (I prefer a rectangular black box hide for this) directly under the heat lamp(s) and place a light-colored slab of stone (ex: flagstone, sandstone) or hardwood on top to create a basking platform. The hide underneath will be the warm hide. The heat lamp should be able to heat the warm hide to the target temperature, but this can vary depending on room temperature, thickness of the basking surface, etc.
If your warm hide is not getting warm enough: add a heat mat under the hide box, covered with 1” of substrate to prevent direct contact. Plug this heat mat in to a thermostat such as the Inkbird brand. Place the thermostat probe inside the warm hide to regulate its temperature correctly. For best results, schedule your heat mat to turn off a few hours after sunset rather than immediately at sunset to replicate that lingering-warmth effect nocturnal reptiles benefit from in the wild!
To measure the general temperature of different areas of your terrarium, you can use an infrared thermometer (a.k.a. temperature gun). To passively track basking temperature, use a digital probe thermometer, with the probe placed on the basking surface under the heat source.
Humidity
African fat-tailed geckos do best in an environment that cycles between wet and dry seasons:
- Rainy/warm season - 70-80% daytime, 100% nighttime
- Dry/cool season - 50% daytime, 70-75% nighttime
It is also important to your gecko’s health to provide them with consistent access to an area of higher humidity. This can be done with a “humid hide” - a cave or hide with moistened substrate (NOT sphagnum moss), placed on the cool end of the enclosure. This helps your gecko shed successfully and stay hydrated. Keep the humidity levels in this hide around the same as your current target nighttime humidity.
You can monitor humidity levels in your humid hide with a digital probe hygrometer with the probe placed in the middle. You will need another device if you want to monitor the humid hide separately.
To increase humidity levels in the enclosure, use a handheld pressure sprayer.

Diet and Feeding
African fat-tailed geckos are insectivores, which means that they eat insects.
How often an African fat-tailed gecko needs to eat depends on age: The general rule is to offer 2 appropriately-sized bugs per 1 inch of your gecko’s length, or however much they can eat in 15 minutes. Juveniles should be fed daily, and young adults fed every other day/every 3 days. Adults whose tail is fatter than their neck can be fed every 5 days.
Here are some feeder insects you can offer:
- Crickets
- Dubia roach nymphs
- Discoid roach nymphs
- Black soldier fly larvae
- Mealworms
- Darkling beetles
- Hornworms
- Silkworms
- Grasshoppers/locusts
The key to providing a healthy, balanced diet for your pet is VARIETY. Provide as varied of a diet as you possibly can, and you will be rewarded with a healthier pet that always looks forward to mealtime.
Insects should be gut loaded with either a commercial gut load product or a mix of either baby cereal, fish flakes or high grade dry dog/cat food as well as leafy greens such as endive, dandelions or romaine lettuce. Gut loading ultimately means that the prey insect is acting as a vehicle to pass on beneficial nutrients to your gecko.
Feeder insects can be easily sourced online from reputable breeders such as Dubia.com, Beastmode Silks, and Luna Roaches.
Supplements
All insect feeders should be lightly “dusted” with calcium powder to balance the calcium-phosphorus ratio. Multivitamin powder can be used every once in a while to provide extra nutrients. All-in-one powders provide a balanced dose of both at once.
There are many options in terms of supplements, but Repashy CalciumPlus LoD is a solid all-in-one supplement for African fat-tailed geckos that have appropriate UVB. For best results, use as directed by the manufacturer.
