his month (Feb. 2006) we stay in South America and
on to the Pimelodidae
family and a very nicely
marked species, the "Sailfin Pim", Leiarius
pictus. This genus comprises of three species,
the other two beingL.
are more closely related to the sub-family Surubiminae,
the shovel noses, and that will maybe give you an
idea of this catfishes temperament, not to be messed
juveniles of this species have rounded caudal fin
lobes, pointed in adults, and longer maxillary barbels
in ratio to body size and the colour is less intense
though this is a stunning catfish, as an adult it
is not really a fish for the home aquarium, as it
will need to be housed in a huge tank as it will get
very nervous and will try to escape the confines of
the aquarium if its barbels can touch the both sides
of the glass sides at the same time, so it would need
to be a least 7' 0" long by 24" in width.
If you are able to accommodate these requirements
you will need a well covered tank with dim lighting,
floating plants may help here, with strong external
filtration and caves for cover. Large smooth rounded
boulders and branches would complete the aquascape.

America: Amazon and Orinoco River basins.
Up to 18dGH
Head narrow, flattish above,
upper jaw slightly longer than the lower. On adult
specimens the maxillary barbels extend to a little
beyond the dorsal fin, the inner mandibular barbels
to base of pecoral fin and the outer mandibular barbels
to the middle of the pectoral fin. Maxillary barbels
extend well beyond the tips of the caudal fin in juvenile
specimens. Body is heaviest under base of dorsal fin
spine. Large sail-like dorsal fin has 9-10 soft rays;
caudal fin deeply forked.
Body dark brown with darker
spots, lighter on underside. Two pale bands, the first
extending from the base of the dorsal fin spine toward
the ventral fin, then laterally along the body to
the caudal base; the second thinner band lies parallel
to the first originating from approximately the base
of the third to sixth soft dorsal fin rays. Dorsal,
adipose and caudal fins with large round dusky spots.
Anal and ventral fins with smaller spots. Barbels
ringed with light and dark.
Care & Compatibility
This fish can be very territorial
and a predator in aquarium set-ups and as such can
only be kept with large cichlids or fish such as the
Giant Gourami. It can not be mixed with other members
of the Pimelodidae family as they are too aggresive
Males are slimmer
Live fishes, prawns and large
to the upper jaw. (maxillary barbels). Mandibular barbels: Pertaining to
the lower jaw. (mandibualr barbels).
