The Pilbara Smooth Knob-tailed Gecko (Nephrurus levis pilbarensis) is one of the most distinctive-looking lizards in Australian captive collections. Its head is huge in proportion to its body, its eyes are enormous, and the short tail ends in a small rounded knob rather than a point. It is a desert burrower from the Pilbara region of Western Australia, nocturnal, secretive, and best kept as a display species rather than a regular handling gecko. Adults typically reach 12 to 18 cm including tail.
In Queensland a wildlife keeper's licence is required. See our Queensland Reptile Licence Guide before purchasing.
Enclosure
Floor space is the priority. An enclosure around 60 x 30 x 30 cm suits a single adult or established pair well. The most important feature of a knob-tail enclosure is the substrate, and getting this right is non-negotiable.
Substrate setup
Use fine natural sand, or a sand and soil mix. The substrate must be at least 8 to 10 cm deep. Divide the enclosure into two distinct zones:
- Warm end (under the heat source): dry substrate where the gecko can thermoregulate.
- Cool end: substrate kept moist enough to clump and hold a burrow. This is how knob-tailed geckos maintain their hydration in the wild. If they cannot burrow into moist substrate, they will dehydrate regardless of how much water is available.
The geckos will dig burrows and often plug the entrance to maintain the microclimate inside. Do not disturb these burrows unnecessarily. An alternative to a moist cool end is a deep, humid hide filled with moist substrate. Either approach works, but one or the other is required.
Lightly mist the cool end every 2 to 3 days in summer and less frequently in winter.

Heating
The Pilbara region is hot and arid. This gecko needs a proper warm zone to thermoregulate at night when it is active.
- Warm end: 30 to 32°C
- Cool end: 24 to 26°C
- Night: allow to drop to 18 to 20°C, which reflects the cooler desert nights this species is adapted to.
Use a thermostatically controlled heat mat or heat tape under the warm end of the enclosure. Verify temperatures with a thermometer. Browse our heating and thermostat range.
Lighting and UVB
Knob-tailed geckos are strictly nocturnal and do not require UVB to survive. Low-level optional UVB (2.0) on a 12-hour cycle will not cause harm and may offer some benefit. More importantly, if no UVB is provided, ensure consistent calcium and vitamin D3 supplementation at every feeding. Turn all lighting off at night. Even a low ambient light level during the day helps maintain natural behaviour cues.
Feeding
Insectivores that hunt at night. Offer food in the evening after the lights are off so the gecko can hunt in darkness as it would naturally.
- Suitable prey: crickets, small woodies, roaches, and small mealworms. Avoid prey that is too large for the gecko to overpower easily.
- Juveniles: every 2 to 3 days.
- Adults: every 3 to 4 days.
Gut-load feeders for 24 to 48 hours before offering. Dust insects with calcium at every feeding and use a reptile multivitamin periodically. Remove uneaten insects from the enclosure the following morning. Provide a shallow water dish, changing it regularly.

Handling and Temperament
Knob-tailed geckos are best kept as display animals and should be handled as little as possible. They are nocturnal and secretive by nature, and frequent handling causes significant stress. When handling is necessary, do so briefly, low over a soft surface, and never grab or restrain by the tail. Like all geckos they can autotomise (drop) the tail if handled roughly or frightened.
