African Fat-Tailed Gecko Care Guide: Humid-Hide Husbandry
African fat-tailed geckos are gentle, ground-dwelling nocturnal lizards that need belly heat, a moist hide and a diet of insects. This guide walks through enclosure setup, the crucial humid hide, temperature gradient, feeding and handling so your gecko sheds cleanly and stays healthy.
Quick answer
African fat-tailed geckos (Hemitheconyx caudicinctus) are calm, terrestrial, nocturnal geckos that need warmth from below, a moist hide for clean shedding, and a diet of insects. Set up a 60x30x30 cm floor-oriented terrarium with a warm side of 30-33°C, a cool side around 24-26°C, and a central humid hide, and you have covered the essentials.

Enclosure and substrate
Unlike arboreal geckos, fat-tails live on the ground, so floor space matters more than height. A single adult needs at least a 60x30x30 cm enclosure with a secure lid. Provide three hides: one on the warm side, one on the cool side, and a moist hide in the middle.
Three hides — warm, cool and a moist middle hide — let the gecko choose its own temperature and humidity.
For substrate, use coconut fibre, a soil mix, or paper towel for a quarantine or hospital setup. Avoid loose sand with young or unwell geckos, as accidental ingestion can cause gut impaction. Keep the enclosure escape-proof — these geckos are stronger diggers and pushers than they look.
Heat and the humid hide
Fat-tailed geckos absorb heat through their belly, so the primary heat source should be an under-tank heat mat controlled by a thermostat, placed under the warm-side hide. Aim for a surface temperature of 30-33°C on the warm end and 24-26°C on the cool end. A thermostat is not optional — an unregulated mat can overheat and burn the animal.
The humid hide is the single most important feature for this species. Fill a small closed hide with damp sphagnum moss and keep it lightly moist at all times. This is where the gecko will retreat to shed; without it, shed can stick to the toes and eyes and cause damage.
Fat-tailed geckos are insectivores — dust feeder insects with calcium to prevent metabolic bone disease.
Diet and supplements
Fat-tailed geckos are strict insectivores. Feed appropriately sized crickets or dubia roaches — no wider than the space between the gecko's eyes — plus occasional treats like a waxworm or black soldier fly larvae. Feed juveniles daily and adults every two to three days.
Dust insects with a calcium supplement at most feeds and a calcium-with-D3 or multivitamin one to two times a week. A shallow water dish should always be available. Overfeeding fatty worms leads to obesity, so keep the tail plump but not bloated.
Handling and temperament
Fat-tailed geckos are among the most docile lizards, but let a newcomer settle for a week or two first. Handle low over a soft surface, support the whole body, and keep sessions short at first. Never grip the tail — like many geckos they can drop it, and a regrown tail looks different and no longer stores fat as well.
Quick FAQs
Do African fat-tailed geckos need UVB? They can thrive with a good D3-dusted diet, but low-level UVB is a helpful bonus for long-term bone health.
Can I use a heat lamp instead of a mat? Belly heat from a thermostat-controlled mat suits their biology best; if you use overhead heat, still ensure a warm floor surface and never let it dry out the humid hide.
How often will my gecko shed? Frequency varies with age and growth; juveniles shed more often. A working humid hide makes each shed come off in clean pieces.
Is loose sand safe? It is a risk, especially for young or sick geckos. Coconut fibre, soil mixes or paper towel are safer everyday choices.
