Size 320mm or 12.6" SL. Find near, nearer or same sized spp.
IdentificationThe pictured specimen was imported from Peru although very similar species are imported from the Rio Orinoco, Venezuela and the Rio Tocantins, Brazil. Although imported for several years beforehand, this species was given an L-number in 2010.
SexingMature males have considerably more odontodal growth on most fins rays but the pectorals are most adorned. Females fill out quite considerably in relation to the slender males.
General RemarksThe pictured specimen was imported from Peru although similar species are imported from the Rio Orinoco, Venezuela and the Rio Tocantins, Brazil. With respect to coloration, this species closely resembles L097 and Pseudacanthicus sp. "Alenquer" from Brazil. They even share the same changes in coloration along maturation, but are easily told apart due to their differing body shape.

FeedingCarnivore although not a predator, prawns and chopped mussel appear favourites and promote favourable growth. Some vegetable should also be provided and thus balances diet.
FurnitureA potentially large pleco that will need robust decoration in the tank. Fairly reclusive and will need cover to hide in. Care must be taken that no other inhabitants of the aquarium attempt to dispute ownership of this cover. This fish will fight for the territory and, with its array of spines and hooks, can cause serious damage.
CompatibilityGenerally peaceful but territorial from a young age. Some large specimens are aggressively territorial and may cause problems if housed with other large nocturnal fish.
Suggested TankmatesThe temptation with large tough Loricariids is to keep them with large, tough other fish such as Oscars or other brutish characters. This actually works quite well with most omnivorous or mainly vegetarian plecos. Pseudacanthicus however are big messy carnivores, but, like all large plecos, produce vast amounts of waste and as such would require monumental filtration to house alongside non-catfish ''equals''. It is better to think of these catfish as the centerpiece fish and stock their aquarium with medium sized (preferably omnivorous) fish.
BreedingUnknown although almost certainly a cave / pipe spawner.
