A species of Pseudoplatystoma distinguished
by a combination of the following features: rays on
dorsal and ventral lobes of caudal fin with fused
branches or not separated as in other species of Pseudoplatystoma;
wide, straight, dark vertical bars on sides; no loops
on nape and associated areas; dorsal and ventral regions
of pectoral fin pale with no spots; dorsal fin with
few or no spots (sometimes 5 spots); 43 vertebrae;
adipose fin with few large spots (6–7 spots);
areas surrounding the procurrent rays of dorsal fin
without spots; posterior region of the metapterygoid
wider than in other species, forming a depression
or notch in the dorsal margin of the suspensorium.
Aquarium Care: Its tank should have
a shaded area at the back such as a large branch and
plants to hide under as it is nocturnal, and also
the lighting should not be too bright. Should not
be kept with any fish that is smaller than itself
and it also should be housed in a very large tank.
The best companions would probably be large Pacu's
or similar sized fish that would not be swallowed.
In my opinion this wonderful looking Pim should only
be kept in Public Aquariums as it can damage
its large nose if kept in too confined an area, it
can get jumpy too if feels its barbels on the tank
sides as it turns around. It can also go of its food
as well, if it is anyway disturbed. Diet:
In their natural habitat they eat other fish such
as characins and other catfish, they also eat freshwater
crabs. In the aquarium a diet of earthworms, freshwater
fish such as trout and also shrimp and prawns. You
should only feed when it starts looking actively for
it, as they will rest for a few days after feeding
to digest their food. Remarks:
There has been 5 new species described by Buitrago-Suárez,
U.A. and B.M. Burr in 2007, to go alongside P.
fasciatum and P.
corruscans. These species are
P. punctifer (Castelnau), P.
reticulatum Eigenmann & Eigenmann,
P. orinocoensen, P.
and P. magdaleniatum. So far P. punctifer
is the only species that has not been accepted
in some publications in print and on the internet.Two species (P. punctifer ? and P. tigrinum)
are sympatric in the Amazon Basin, two (P. metaenseand
P. orinocoense) are sympatric in the Orinoco
Basin, and two others, P. corruscans and
P. reticulatum, are sympatric in the Paraná.
Pseudoplatystoma magdaleniatum and P.
fasciatum each occur as the only species of Pseudoplatystoma
in their respective individual ranges.
