A species of Pseudoplatystoma distinguished
by a combination of the following features: loop–like
dark bars forming a reticulating pattern, never straight
as in P.
fasciatum, P. orinocoense
and P. punctifer ?; dark, loop–like
bars join those in the dorsal region of the body forming
distinct cells; longer loop– like dark bars,
extending far below the lateral line; head shows either
spots or loops; 42–43 vertebrae; anal fin always
with spots; no clear demarcation between dark dorsal
and pale ventral regions; lower jaw pointed. 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. reticulatum Eigenmann
& Eigenmann, P. orinocoensen, P.
metaense, and P.
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.
Central Amazon and Paraná River in Argentina,
Bolivia, Brazil, Paraguay, and Uruguay.
