Facultative air-breathing in the genus (Ref. 126274); Lives on sandy bottom where it feeds on worms and micro-crustaceans. Mature males develop a huge labial veil and teeth with spoon-shaped crow (versus pointed ones in females and juveniles). Unlike most Loricariidae, they don't have well developed odontodes on the snout and pectoral fins. During reproduction, the males bear a cluster of eggs fixed to their lips, which they provide with ventilation during movement. About one week after hatching, the alevins leave their parent's protection (Ref. 35381).
