- Southern China, northern Vietnam, Myanmar – montane forest
- Protection status
- Not listed under CITES
- Brumation

- Cohabitation
- Keep them singly. Snakes are solitary and do not seek company — a shared hide is competition for the best spot, not social behaviour. The concrete reason is the feeding accident: if two animals grab the same food item, one can swallow the other along with it. On top of that, once they are kept together you can no longer tell which animal has eaten and which is losing weight. For breeding, put them together under supervision and separate them again afterwards.
Notes
The commonest keeping mistake is caring for it too warm — above 27 °C is tolerated poorly. It lives hidden and burrows, and is rarely seen. Wild-caught animals are considered problematic; captive-bred ones are markedly more robust.
