|Cat-eLog Data Sheet|
|Scientific Name||Pseudacanthicus pitanga Chamon, 2015|
|Common Names||L024, Red Fin Cactus Pleco
|Type Locality||Rio Tocantins, Pará, Brazil|
|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. The specific epithet comes from the Tupi-Guarani word for red, in reference to the color of the fins.|
|Size||340mm or 13.4" SL. Find near, nearer or same sized spp.|
|Identification||Pseudacanthicus is a member of the Acanthicus clade. Species of the Acanthicus clade are distinguished from other Loricariidae species by the presence of (1) longitudinal rows of keels (pointed odontodes) along the body sides; (2) eight or more dorsal-fin rays (vs. six or seven in most other loricariids except Pterygoplichthys, Chaetostoma, Pogonopoma and Pseudancistrus pectegenitor); (3) seven to eight infraorbitals (vs. usually five or six); (4) five anal-fin branched rays (vs. usually four); and (5) presence of hypertrophied odontodes along the snout margin (vs. hypertrophied odontodes absent in other loricariids except Isbrueckerichthys and Pareiorhaphis, in Neoplecostominae; Panaque and Pseudancistrus and Neblinichthys, in Ancistrini; and most dimorphic males of Loricariinae). Within the Acanthicus group, Pseudacanthicus is distinguished by the presence of two small plates in the posterior area of the compound pterotic (vs. one median plate or plate absent), and by the presence of narrow premaxillae with a small number of elongate and curved teeth (except from Leporacanthicus).
The German common name for this genus is ''Cactus Pleco''. A good name! Similar to L025 but ultimately smaller with a less contrasting overall colouration making it more drab in appearance.
|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.|

|Temperature||23.0-27.0°C or 73.4-80.6°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||Not as shy as some members of the genus although a shady retreat should be provided.|
|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. All sizes of barbs work surprisingly well.|
|Breeding||Unknown but almost certainly a cave / pipe spawner.|
