Biology:  Known only from the type locality, a small stream flowing along a limestone creek bed through primary forest. The stream plunges down a steep 20 m-high ramp next to the sea into a mangrove-lined inlet near the village of Kokas on the northern Fakfak Peninsula. The fish was collected about one kilometer upstream, in a circular pool with an approximate diameter of 15-20 m and maximum depth of about 0.5 m and this pool was situated only about 20 m downstream from a series of limestone fissures that appear to be the stream’s underground origin (Ref. 79630).
