This frog is native to South East Asia, and usually lives on the forest floor, in rice fields, and even inside homes. These frogs are voracious eaters, and will eat flies, crickets, moths, grasshoppers, earthworms and more. Painted frogs hide under leaf litter during the day hours and eat in the evening.
Like many other narrow-mouthed frogs, painted frogs have the ability to expand themselves when threatened, and to secrete toxic glue-like substances from their bodies as a defense mechanism. They are also able to survive dry conditions by burying themselves in the ground and waiting for rain.
The species is a potential invasive species. It has been introduced and become established in Guam, Singapore, Borneo and Celebes with specimens noted in Australia and New Zealand.
In India, the frogs call after the first heavy monsoon showers in April–May. The males call while afloat in pools of water. The pulses of the calls recorded in India were 28–56 per second with a frequency range of 50–1760 Hz. In Thailand the dominant frequency was 250 Hz (duration 560–600 ms long) and 18–21 pulses/call..
