Size 240mm or 9.4" SL. Find near, nearer or same sized spp.
IdentificationA few colour forms exist, these are separate from L24 and L25 however. 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.
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.

Jump to next section Husbandry Information
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.
FurniturePrefers a dimmer tank and requires a suitable sized cave.
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 bred in the aquarium, the fish are sexually mature at about 170mm SL, see Shane's World article.
