species occurs in Guyana, Peru and French Guiana and
throughout the Amazon basin. It is likely that the
species is more widespread, but this is complicated
by the current taxonomic debate. Occurs over sand
in creeks and rivers. Very voracious. Sexual
Differences: The genital tracts are organised
like those of Rhamdia. Eye size changes according
to sex. Aquarium Care:Treat
as you would do with any member of the Pimelodus in
that they will be predatory on small fishes in the
aquarium and it is also better to keep them in small
groups rather than singularly, as this will dilute
the aggression. As this is one of the largest species
in this genera it would need a large tank to accommodate
an adult sized fish of 34cm. S.L. Diet:
Will eat any aquarium prepared foods such as tablets,
pellets, frozen and live foods. Not fussy eaters.
