This species can be distinguished from L.
saetiger, and L.
tentaculatusby having abdominal
plates (vs. absent), from L. schomburgkii
and L. saetiger by having dark spots in the
dorsal and caudal fins (vs. white spots or all dark);
and from L. guacharote by not having the
abdominal plates restricted to a region near the insertion
of the pectoral-fin spine. The Lasiancistrus
species are quite similar to the Ancistrus
genus but have a flatter profile and do not possess
the tentacles on the mouths of this genera. Sexual
Differences: Males have longer pectoral fins
and have a heavier growth of odontodes behind the
gill covers and on the edges of the snout. Aquarium
Care: Relatively easy to keep but large males
may tend to be territorial. Diet:
Bogwood should be provided for rasping on and vegetables
will be their main dietary requirements. Will also
take veg. tablets/wafers, fine live and frozen foods.
