Rheophilic, found near river banks, primarly in small caves and cracks in stones, in flowing water with high turbulence and water speed . Found only in rocky habitats with little or no sand or gravel . Presumably feeds upon plants and other organisms which grow attached to the rocky substrate . Forages on algae using specialised, abrupt movements of the head . Probably a cave-spawner that practices pair-bonding, albeit weakly .
