The species lives in moist and rocky environments in the rainforest. Like many other frogs it's mostly nocturnal and spends the days completely still at a branch. If threatened it curls up like a ball. When it lands it is almost impossible to detect. The eggs are laid in small lumps on the ground right above water. When the larvae hatch they fall in to the water where they metamorphose. The metamorphosis takes up to a year.
The vietnamese mossy frog lives in Mao Son and Tam Dao mountains in northern Vietnam.
