Down Species Information
Size 120mm or 4.7" SL. Find near, nearer or same sized spp.
Identification Adult Lasiancistrus can be separated from all other loricariids by the presence of whisker-like odontodes on the cheeks. In addition, they have evertible cheek odontodes; three rows of plates on the caudal peduncle; and a modified, bar-shaped opercle. The caudal fin is slightly emarginate to forked, with the lower lobe longer than upper. Nuptial males have tentacules on the pectoral-fin spines longer than their associated odontodes; and transluscent tentacules on the snout that have odontodes associated with them. Nuptial males lack hypertrophied odontodes on top of the head and lack long, bristle-like odontodes on the leading edge of the pectoral-fin spine.

An overall brown that can range from light to dark depending on mode. The first one third of the body is covered with small light dots. The fins have darker markings present on the fin rays.
Sexing Females are plumper when gravid and viewed from above.
General Remarks A rather unique little fish as its diet is like no other member of the genus.

Down Husbandry Information
Feeding A wood eater like the members of the genus Panaque. Wood should constitute the bulk of their diet with occasional feedings of vegetables or algae-based wafers. Protein should be fed very sparingly. User data.
Furniture A species tank would replicate a driftwood snag. Furniture is fairly unimportant with the exception that the tank must contain driftwood.
Compatibility Very peaceful.
Suggested Tankmates Found alongside Panaque maccus, P. nigrolineatus, Farlowella vitata, F. mariaelenae, Otocinclus, and Hypoptopoma. Also captured with Corydoras habrosus, C. septentrionalis, and C. venezuelanus ''black.''
