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).
生活在沙质底部在哪里它吃蠕虫与细小的甲壳动物。 成熟的雄鱼发育一个极大的唇罩而且牙齿有匙-形状的棍.(对尖的一些在母鱼与稚鱼中) 不像大多数的甲鲶科鱼类，它们在吻部与胸鳍上不有发展良好的齿。 在繁殖的时候，雄性有附着在他们的唇的一簇卵, 他们在运动的时候以通风提供。 在孵化之后大约一个星期，刚孵化的小鱼离开他们父母的保护。 (参考文献 35381)
