Origin
South-western China (the Yangtze basin); subtropical and montane forests
Protection status
Not listed under CITES; IUCN "Least Concern". Mostly wild-caught in the trade – prefer captive-bred animals.
Brumation
A slight winter cooling matching their subtropical native climate (a few weeks cooler at ~15–18 °C, with a shorter photoperiod), optional for breeding
Cohabitation
Keep singly, or one male with one to two females (a pair or small harem group) in a large, structured enclosure. Never house males together - territorial fights are to be expected. The species is easily stressed by being seen, so visual barriers and dense planting are essential.

Notes

A shy, agile arboreal species; it injures itself on the glass in a panic – dense planting and visual screening are needed. It prefers to drink mist or dew droplets (daily misting or sprinkling). Nomenclature: formerly Japalura splendida (neon tree dragon / green striped dragon). Often wild-caught (check for parasites).
