| Family: | Loricariidae (Armored catfishes), subfamily: Loricariinae | |||
| Max. size: | 13.4 cm SL (male/unsexed) | |||
| Environment: | demersal; freshwater | |||
| Distribution: | South America: Amazon, Essequibo, Oyapock, and Paraguay River basins. | |||
| Diagnosis: | ||||
| Biology: | 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). | |||
