Comments: The type locality is a clear water stream with depth of 0.06-0.30 m and width of 1.5-2.0 m over a rock and cobble bottom, water temperature of 19.7°C and surrounded by limited riparian vegetation.  Nocturnally active with individuals observed swimming during the night and hiding among rocks on the stream bed during the day.  Stomach contents of 2 specimens consisted of dipteran larvae (Chironomidae) and sand, suggesting that this species feeds on autochthonous benthic macroinvertebrates.  Spawns before April since observations during that month in 2009 revealed that its population at the sampling site contained larger numbers of juveniles than adults (Ref. 95056).
