🏠 Enclosure
- Use the enclosure dimensions, heating, humidity, and safety values from the structured care profile and full care guide.
🪨 Enclosure furniture
- 15 cm of compactable coco fibre mixed with clean soil or clay for a stable deep burrow
- Partly buried cork bark hide to start the tunnel and reduce exposed climbing
- Shallow water dish kept accessible beside, not over, the burrow
- Minimal stable decor and low open height; avoid loose rocks and claw-catching mesh
- Keep a clear maintenance route because this species may bolt when its retreat is disturbed
💡 Lighting
- No UVB or specialist lighting required; normal room light provides the day-night cycle
- Photoperiod: 10-12 h of ambient light; no night light
- Keep plant or display lights weak and away from the lid
- Avoid bright or hot overhead lamps that dry the burrow entrance
🌡️ Temperature
- Basking spot: 23-26 °C
- Warm zone: 22-26 °C
- Cool zone: 20-22 °C
- Night: 18-22 °C
💧 Humidity & water
- Target 60-75% humidity, with a shallow dish of fresh water always available
- Keep the lower burrow slightly moist while allowing the surface and entrance to dry and breathe
- Keep spiderlings in small ventilated containers with a moist lower layer and a drier surface area
- During premolt, raise retreat moisture toward 75-85%, not the entire enclosure
- Avoid saturated substrate, stagnant air, mold, and chronic dryness
🪳 Feeding
- Feed according to the prey type and schedule in the structured care profile; remove uneaten prey promptly.
