Chilobrachys dyscolus / vietnam black spiderlings

Chilobrachys dyscolus (Vietnam Black/Blue Earth Tiger) thrives at 24–27 °C with a slight night drop to ~22 °C, and requires 70–80% humidity plus deep, moist substrate for burrowing.
🌍 Natural Habitat
Native to Vietnam, Laos, Cambodia and surrounding Southeast Asia.
Found in humid tropical forest floors with leaf litter, dense root systems, and high moisture.
Fossorial (burrowing) species that constructs deep silk-lined tunnels.
🌡️ Temperature
Ambient range: 24–27 °C (75–81 °F).
Night drop: ~22 °C (72 °F) is acceptable.
No basking heat required — they prefer stable, warm ambient conditions.
Avoid extremes: prolonged temps below 20 °C or above 30 °C can stress the tarantula.
💧 Humidity
Maintain 70–80% humidity.
Achieved with slightly moist substrate, occasional misting, and a water dish.
Good ventilation is critical to prevent mold growth.
🏠 Enclosure Setup
Substrate depth: 10–15 cm (4–6 inches) of coconut fiber, peat moss, or vermiculite mix.
Keep substrate slightly moist but not waterlogged.
Provide cork bark, hollow logs, or coconut shells for hides.
Add leaf litter, moss, and artificial plants for naturalistic cover.
Ensure secure enclosure — this species is fast, defensive, and heavy webbing.
📏 Size & Behavior
Adult leg span: 14–16 cm (5–6 inches body length).
Known for aggressive feeding response, rapid growth, and extensive webbing.
Not recommended for beginners due to speed and defensiveness.
