Pseudolithoxus tigris is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypostominae, the suckermouth catfishes.[2] This catfish is found in Colombia and Venezuela where it is found in the upper Orinoco and Ventuari River basins. from San Fernando de Atabapo almost to the Casiquiare canal.[1] This species grows to a standard length of 9.4 cm (3.7 in).[3]

P. tigris probably matures at a relatively small size; in a specimen about 5 cm (2 in) SL, the snout and pectoral-fin spine odontodes are already greatly elongated, while the odontodes are only beginning to develop in similarly sized specimens of other species.[4]

P. tigris sometimes appears in the aquarium trade, where it is typically referred to either as the tigerstriped plane pleco or by its associated L-number, which is L-257.[5]
