Terrestrial — floor space first. An adult knob-tailed gecko should live in at least 24" L × 12" W × 12" H; we build toward 36" L × 18" W × 18" H (3 × 1.5 × 1.5 ft, roughly 4.5 sq ft of floor and about a 50-gallon glass equivalent).
- Hatchling / baby
- 12" L × 12" W × 12" H recommended · min 12" L × 12" W × 12" H
- Juvenile
- 24" L × 12" W × 12" H recommended · min 18" L × 12" W × 12" H
- Adult
- 36" L × 18" W × 18" H recommended · min 24" L × 12" W × 12" H
Temperature and heating
Overhead heat (halogen, deep heat projector or radiant panel) on a thermostat, creating a warm-to-cool gradient.
- Basking / warm surface
- 88–92°F warm surface
- Warm side (ambient)
- 82–86°F
- Cool side (ambient)
- 72–78°F
- Night
- 65–72°F
Lighting and UVB
UVB: Low-level UVB beneficial but not strictly required. Run lights on a 12 hours on, 12 hours off photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target 30–40%. Dry setup with a slightly damp burrow area.
Substrate and depth
Sand/soil mix that holds burrows. Depth: 3–4 in.
Diet and feeding
Gut-loaded insects (crickets, dubia, black soldier fly larvae) dusted with calcium; vitamins weekly.
Enclosure tips and furnishing
- Hides on both the warm and cool sides
- Clean water available at all times
- Clutter — cork, leaf litter, plants — for cover
Build list
- Enclosure at adult size — Buy for the adult footprint to avoid repeated upgrades.
- Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
- Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly.
