Dorsal soft rays (total): 6; Anal spines: 0; Anal
soft rays: 20 - 25; Vertebrae: 44 - 46. Laterally
positioned eyes, visible dorsally and ventrally; in
adults, the diameter is 2.2-3.3 times into interorbital
width. Inner mental barbels usually posterior to gular
apex, rarely even with it, and never reaching fleshy
margin of opercle. Outer mental barbels longer, extending
beyond the origin of pectoral fins. Maxillary barbels
variable in length, extending to pelvic fins or beyond.
Pelvic fins when depressed reaching approximately
halfway from anus to anal-fin origin. Habitat:
Collected from both white and black waters; found
in floodplain lakes, small creeks (or caños)
to large rivers and tidal rivers; on sand, mud, and
clay substrates associated with vegetation (e.g. tall
reeds, emergent grasses, and root masses of stream-side
trees). Apparently nocturnal and hide in groups along
stream margins during the day. 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. 6ft x 2ft 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 species along with Sorubim
the two most seen species in this genus. There are
another three that are that bit rarer, S. trigonocephalus,
cuspicaudus and S. maniradii.
