Husbandry requirements
Giant knob-tailed gecko — origin: Arid centre of Australia (rocky ranges and outcrops of the Northern Territory, around Alice Springs). Saxicolous/terrestrial species. Protected endemic species: Australia bans the export of its wildlife, so all legal specimens in the trade come from captive breeding (captive lines) — be wary of animals of dubious origin. Non-venomous; not listed on CITES..
Terrarium temperature gradient
Nocturnal desert species: NO bright hot spot or basking lamp. Create a thermal gradient with a heat mat/cable or a ceramic lamp on the warm side, regulated by a thermostat. A nighttime drop is beneficial (down to ~18-20°C). A cooler wintering (days ~18-22°C for 6-8 weeks) stimulates breeding.
Terrestrial terrarium (glass or PVC) with rocky hides
Floor area takes priority over height (terrestrial species). A single adult or a pair; never house two males together (aggression). Arrange STABLE stacks of flat stones/slate wedged against the terrarium base (not resting on the loose substrate, to prevent any collapse/crushing) forming crevices, plus low hides.
Generally dry environment, but a humid hide (sphagnum/moss) is essential for a proper shed. Light nighttime misting; allow to dry out between mistings.
Substrate slightly moistened at depth to allow stable tunnels, with the surface kept dry. Avoid pure fine sand (risk of impaction if ingested). Always provide a humid hide to aid shedding.
Not essential (nocturnal species) if calcium+D3 supplementation is regular. Low UVB (Ferguson zone 1, ~2-5% UVB) remains beneficial; always provide shaded and hiding areas.
A small dish of clean, fresh, shallow water, refreshed regularly. Light nighttime misting: the animal readily licks droplets off the decor.

Feeding & health
Insectivore — Adult crickets, roaches (Blaptica dubia, Nauphoeta), occasional superworms.
Dust prey with calcium (without D3 at every meal, with D3 a few times a month). Feed an adult 2-3 times a week, juveniles more often. Appropriately sized prey (width smaller than the inter-orbital space). Avoid overfeeding: a species prone to obesity.
Clutch 2–2 eggs/young. Usually 2 large eggs per clutch, with several clutches (2 to 5) per season after a winter cooling period. Incubation at ~27-29°C for about 60-75 days. No marked temperature-dependent sex determination. Monitor the female: risk of egg retention.
- Metabolic bone disease (MBD) from calcium/D3 deficiency
- Dysecdysis (retained shed on the toes and tail knob) if humidity/humid hide is insufficient
- Digestive impaction from ingesting unsuitable substrate (fine sand)
- Obesity linked to overfeeding
- Egg retention (dystocia) in the breeding female
