Description:
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.
There has been 5 new species described by Buitrago-Suárez,
U.A. and B.M. Burr in 2007, to go alongside P.
tigrinum, P.
fasciatum and
P.
corruscans. These species
are P.
punctifer (Castelnau),
P. reticulatum Eigenmann & Eigenmann,
P.
orinocoense, P.
metaense, and
P.
magdaleniatum.
So far P. punctifer is the only species
that has not been accepted in some publications.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.
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.
