|Cat-eLog Data Sheet|
|Scientific Name||Pseudacanthicus sp. (L452)|
|Common Names||L452, Mustang Cactus Pleco|
|Pronunciation||SUE dah KAN thi cuss|
|Etymology||Pseud- Greek: False, Acanthicus - Greek: Spiny, Thorny. Literally "False Acanthicus" referring to this genus being similar to, yet different from, Acanthicus.|
- CotM 2012 September
|Size||320mm or 12.6" SL. Find near, nearer or same sized spp.|
|Identification||The 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.|
|Sexing||Mature 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 Remarks||The 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.|
|Distribution||South America: Ucayali drainage in Peru, Rio Tapiche close to Requena.
Amazon, Upper Amazon, Marañón, Ucayali, Lower Ucayali, Tapiche (click on these areas to find other species found there)

|pH||6.5 - 7.5|
|Temperature||25.0-28.0°C or 77-82.4°F (Show species within this range)|
|Feeding||Carnivore although not a predator, prawns and chopped mussel appear favourites and promote favourable growth. Some vegetable should also be provided and thus balances diet.|
|Furniture||A 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.|
|Compatibility||Generally 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 Tankmates||The 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.|
|Breeding||Unknown although almost certainly a cave / pipe spawner.|
|Breeding Reports||There is but a single breeding report, read it here.|
