Collected alongside a fast running part of a creek that flows down a boulder-strewn area, with a fall of approximately one in every five meters, a place where people find leisure and can slide down the rocky face. This rocky open area is surrounded by a primary forest. This species lives between tree roots and fallen leaves attached to boulders at the edges of the stream, and between boulders. It was also collected a in places where the water ran slower, but was not found in still water surrounding the rocky waterslide. At the time of collection (September 2006), the water at the collecting site was clear, pH 7, 27.6°C, conductivity was <1 μS/cm. (Ref. 94444).
