Scientific NamePseudacanthicus leopardus  (Fowler, 1914)
Common NamesLDA073, Leopardsugemalle (Denmark)
L600
Type LocalityRupununi River, Guyana, {for map: 2.5°N, 50°20'W} 2°-3°N, 50°20'W.

In the original description of this species, Fowler (1914) wrote that the fish were from “...the Rupununi River, in the highlands of British Guiana. ...approximately secured in North Latitude 2° to 3°, and West Longitude 50° 20'.” Although the latitude data is imprecise, the longitude data must also be inaccurate, because the Rio Rupununi is located at approximately 59°W Longitude, not 50°W Longitude as Fowler reported. So as not to unilaterally revise Fowler’s original record, the type locality data is being preserved, and displayed as “2.5°N, 50°20'W”, averaging the two latitude values reported by Fowler and not correcting the longitude value.
Synonym(s)Stoneiella leopardus
PronunciationSUE dah KAN thi cuss
EtymologyPseud- Greek: False, Acanthicus - Greek: Spiny, Thorny. Literally "False Acanthicus" referring to this genus being similar to, yet different from, Acanthicus

Size 350mm or 13.8" SL. Find near, nearer or same sized spp.
IdentificationAs juveniles these fish exhibit vibrant yellow/orange coloured unpaired fins. With increasing age the spotting of the body 'leaks' more and more onto the previously orange colored fins. Sometimes referred to as 'L600' but not recognised 'officially' as such by DATZ etc. It actually appeared in the December 1996 DATZ alongside L114. Wels Atlas II also equates this to L114.
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.

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.
FurnitureProportionally sized pieces of bogwood (the fish does not appear to particularly like rockwork) are a good idea as are equally dimensioned pipes. Plants are just a nuisance to this fish and while not orally molested, they tend to be battered by the fishes movement.
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 centrepiece fish and stock their aquarium with medium sized (preferably omnivorous) fish. All sizes of barbs work surprisingly well.
BreedingHas been spawned in captivity and is a cave spawner. The very close relative, P. cf. leopardus, has been spawned in captivity and an article can be found in Shane's World.
