Etymology The genus name is derived from Leios, meaning smooth and Arius which is a Greek for "dealing with Mars, warlike, belliose". It's the name of another catfish genus, so the combination is "smooth Arius". This specific epithet literally means painted (pictus=painted) and refers to the spots of the adult of the species.

Size 600mm or 23.6" SL. Find near, nearer or same sized spp.
Identification This catfish is sometimes confused with Leiarius longibarbis (formerly known as L. marmoratus). The overall body colour of L. pictus is dark brown with darker spots, with a lighter underside colouration. More noticeable in juvenile specimens this catfish has two pale bands, the first extends from the base of the dorsal fine spine toward the ventral fin, and then laterally along the body to the base of the caudal; the second thinner band lies parallel to the first originating from the base of the third to sixth soft dorsal fin rays.
Sexing See the images above of the male and female genital areas. Observation of cpative adult fishes points towards females tending to be more heavily built and robust than the males, which tend to be slender.

Jump to next section Husbandry Information
Feeding Carnivore feeding on a very mixed and varied diet including earthworms, whole prawns, mussels, floating sticks/pellets and catfish pellets. In their natural environment they would feed upon other fish.
Furniture Large, spacious tank with open space for night time cruising. A large shady bogwood root or pipe that the catfish can retreat to during the day is also required. Ensure the heater is in the open and not in a place where the catfish may try and hide.
Compatibility Ideally suited to life with other large fish. These catfish are predatory and will eat smaller fish if hungry.
Suggested Tankmates Other large catfish such as Pseudodoras, Oxydoras, Pterodoras and Megalodoras, Oscars and larger characins.
Breeding There are no known aquarium spawnings of this catfish. This is most likely due to the size that these fish can attain and hence the subsequent size of aquarium in which to spawn them.
Breeding Reports There is no breeding report.
