Anal soft rays: 18 - 22; Vertebrae: 50 - 54. Distinguished
from its congeners by the following characters: caudal
fin deeply forked; outer, unbranched principal rays
of upper and lower lobes longest in each lobe and
about equal in length; posterior fontanelle elongate,
forming conspicuous groove on supraoccipital bone,
skin pigmented black in groove (vs. congeners which
are without elongate posterior fontanelle, supraoccipital
groove, or black pigment); unique in having combination
of elongate body and broad-shaped head (vs. congeners
with either elongate body and head, or stout body
with broad head). Habitat: Sorubim
cuspicaudus occurs west of the Andean Cordillera
Oriental, and is endemic to three major drainage basins
in northwestern South America: Lago Maracaibo, Ríos
Magdalena and Sinu. Miles (1947) reported that Sorubim
(referred to as S. lima) was not found in
the upper reaches of the Río Cauca in northern
Colombia. The cis/trans-Andean distribution pattern
exhibited by Sorubim is repeated by some
other lowland fish groups that have been critically
examined in recent years (see references in Vari (1988)
and Harold & Vari (1994). Aquarium Care:
Anything large enough will fit into its mouth so you
should choose tankmates carefully. Large Cichlids
or Plecos would be good companions or larger Characins,
but they will also co-exist with one another, so 2
or 3 individuals brought together as juveniles in
a larger tank (min. 7ft x 3ft x 2ft) would also be
a good choice. Diet: In the aquarium
it is important to try and wean them of live food
so as not too make them too dependent on it and also
not forgetting the disease factor as well. They will
take a variety of larger foods such as earthworms,
frozen bloodworms, tablet and pellet food. You can
try prawns and also frozen fish pieces such as lancefish
This is one of the largest species in this genera
so would need a large tank to house a fish that will
get to 80cm (32ins) in adulthood. Identified by its
extremely pointed caudal fin lobes.
