Comments: Inhabits clear streams with sand and granitic rocks bottoms covered by dense mats of the plant <i>Apinaga multibranchiata (Podostemaceae) in areas of fast water.  Feeds on larvae of aquatic insects such as simuliids and trichopterans that were found among the podostemacean plants.  A few ants and spiders were also found in the stomachs.
