Cat-eLog Data Sheet
Scientific Name	**Pseudacanthicus leopardus** (Fowler, 1914)
Common Name(s)	L600, LDA073
Type Locality	Rupununi R., Guyana, 2°-3°N, 50°20'W.
Synonym(s)	Stoneiella leopardus
Pronunciation	SUE dah KAN thi cuss
Etymology	Pseud- Greek: False, Acanthicus - Greek: Spiny, Thorny. Literally "False Acanthicus" referring to this genus being similar (but different from) to Acanthicus.
Species Information
Size	350mm (13.8") SL. Find near, nearer or same sized spp.
Identification	As 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.
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.
Habitat Information
Distribution	South America: Rupununi River basin in Guyana and Upper Rio Branco in the Amazon drainage. Guyana Waters, Coastal Rivers of Guyanas, Essequibo, Rupununi (hover or click on these areas to show maps or find other species found there) Amazon, Middle Amazon (Solimoes) , Negro, Lower Negro, Branco (hover or click on these areas to show maps or find other species found there)
Temperature	25.0-29.0°C or 77-84.2°F (Show others within this range)
Husbandry Information
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	Proportionally 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.
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	Unknown although almost certainly a cave / pipe spawner. The very close relative P. cf leopardus has been spawned in captivity and an article can be found in Shane's World.
