|Size||240mm or 9.4" 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).
A few colour forms exist with more or less red/orange in the fins and, rarely, with no red. Some fish are more camel coloured than the more dark brown base colour. Additionally, the reddish/orange colouration in the caudal fin varies with age as well as amongst individuals. A certain way to ID this fish is the size of the spots on the head, they should be about the same size as the other spots on the body.
|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.|
|Distribution||The majority of specimens that enter the aquarium trade originate from the Rio Demini in the Rio Negro drainage, Brazil.

|pH||5.6 - 7.0|
|Temperature||24.0-28.0°C or 75.2-82.4°F (Show species within this range)|
|Other Parameters||A black water fish, best kept in slightly acidic, softer water.|
|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||Prefers a dimmer tank and requires a suitable sized cave.|
|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 centrepiece fish and stock their aquarium with medium sized (preferably omnivorous) fish. All sizes of barbs work surprisingly well.|
|Breeding||Has been bred in the aquarium, the fish are sexually mature at about 170mm SL, see Shane's World article.|
