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.
