Vertebrae: 35. Can be diagnosed by a combination of
the following characters: dark spots randomly distributed
over dusky region on body; side of body with few (no
more than 5) straight dark vertical bars; 2 or 3 loop-like
bars; adipose fin with 5-7 spots; surrounding areas
over dorsal procurrent caudal rays with 5-8 spots;
35 vertebrae; and pectoral and pelvic fins pale with
no dusky pigmentation. 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. 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.
Eigenmann, P. orinocoensen, P. metaense,
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. metaense and 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.
