How long do green tree pythons live
GTPs live 15–20 years. They are sensitive: wrong humidity causes respiratory infection and stuck sheds; incorrect perching stresses them; starvation from refusal is common in poorly set-up animals. They are not fragile by nature but unforgiving of husbandry error.
Arboreal enclosure
Use a tall enclosure (18×18×36 in / 45×45×90 cm minimum for an adult) with horizontal branches at multiple heights for the signature coil. Provide a hiding spot near a basking branch. Substrate that holds humidity (cypress, sphagnum). Secure, well-ventilated lid. They sit up, not on the floor.
Humidity: the make-or-break
Maintain 60–80% humidity with a drop at night, via misting and a humid hide; too dry = respiratory disease and retained shed, too wet = scale rot. Basking 82–88°F (28–31°C), ambient 75–82°F (24–28°C). A thermal gradient on the branch. Misjudged humidity is the #1 GTP killer.
Diet and the defensive bite
Feed thawed rodents (appropriate size) every 10–14 days for adults, weekly for juveniles. GTPs are ambush feeders and may strike defensively — use tongs, not hands, and do not handle routinely. They are best appreciated as living art. Never feed live prey. A stressed GTP refuses food for months; check husbandry first.
Beginner mistakes to avoid
- Treating it like a handleable pet — it is a display snake.
- Wrong humidity — respiratory disease and bad sheds.
- Floor-based setup — they need perches to coil.
- Hand-feeding — painful defensive strikes.
