The frog lives on the west side of the rock with fast-flowing water at an altitude of 800m~850m or on the rock wall where the waterfall falls directly. Adult frogs often climb on the cliffs beside the waterfall during the day, jump into the gaps in the waterfall when disturbed, and hide on the west side of the stone or shrubs at night. The breeding season is from April to August, and the eggs are attached to the rock cracks in the waterfall in groups. Tadpoles live in rapid waters with wide streams, lush vegetation on both sides, and many boulders in the stream, and often cling to the bottom of the rocks.
