|Scientific Name||Pseudacanthicus sp. (L273)|
|Common Names||L273, Titanicus Pleco|
|Type Locality||Rio Tapajós, 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.|
|Size||300mm or 11.8" 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).
A variably marked species, the best examples of which can be unbelievably beautifully marked. Other individuals are no where near as striking in appearance but all can be identified by an unusual almost metallic sheen displayed on the back half of the body of the fish.
|Sexing||Males appear to display the brighter more cosmetically attractive patterning. Females are more drab even from an early age.|

|pH||6.0 - 7.0|
|Temperature||23.0-28.0°C or 73.4-82.4°F (Show species within this range)|
|Other Parameters||Clean, clear well-oxygenated water is required for this species.|
|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||Requires a suitable sized cave, preferably wood, and is quite secretive.|
|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 other large tough fish such as Oscars or other brutish characters. This actually works quite well with most omnivorous or mainly vegetarian plecos. Pseudacanthicus despite their defensive protection can be bullied by faster moving fish of similar size. They are carnivores and only eat vegetables when their preferred food is unavailable. The amount of waste produced depends on their diet but is considerably less than a Panaque or Pterygoplichthys of similar size.|
|Breeding||Unknown although almost certainly a cave / pipe spawner.|
|Breeding Reports||There is no breeding report.|
