📖 Overview

Facultative air-breathing in the genus ; 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 .
