"Tiger Shovelnose" is an out-and-out predator,
so it 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
Similar to Pseudoplatystoma
P.tigrinum has more of a striped pattern.
The specimen pictured above was taken at The Port
Doree Public Aquarium in Paris, France.
There has been
a small influx to the hobby of a crossed version of
this fish and a close relation Pseudoplatystoma
tigrinum with the Red Tailed Catfish (Phractocephalus
which were primarily hormone bred for the food market
in South America but some found there way into the
aquatic hobby. There are also hybrids between the
Red Tailed Catfish and the Tiger Fish, Brachyplatystoma
a few other large Pimelodid crosses along the way.
My view is that these large fish have an imposing
beauty all of their own without us having to inbreed
them into any mongrel varieties.
The picture above
depicts a crossed variety which may be Phractocephalus
hemioliopterus x Pseudoplatystoma tigrinum
or Pseudoplatystoma fasciatum x Phractocephalus
hemioliopterus or Phractocephalus hemioliopterus
x Merodontotus tigrinus.
In saying all
this there has been aquarists who have successfully
kept Pseudoplatystoma fasciatum and its
close cousin Pseudoplatystoma tigrinum over
the years but weighed against this is the number of
"Tiger Shovelnoses" that have succumbed
in aquarists tanks due to inexperience and neglect.
So please only keep this fish if you can give it 100%
commitmentand give it the bigest tankthat
you can deliver bearing in mind that you will have
to make it a large footprinti.e. plenty of
inches from front to back of tank.
I have to confess
that I have tasted this species on the plate on my
fish collecting trip to Peru in July 2000. The local
name for this fish in Iquitos is "Dorada"
and it is delicious.
There has now 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. orinocoensen, P. metaense, 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. 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.
Corintijns, Essequibo, Orinoco and Paraná River
Body elongate and streamlined,
head long and depressed. Upper jaw longer than lower
jaw. One pair of long maxillary barbels and two pairs
of shorter mandibular barbels. Caudal fin deeply forked.
Body silvery grey along the
sides, shading to olive along the back. Underside
creamy white. Markings variable, usually vertical
dark stripes and blotches. Fins usually spotted.
Care & Compatibility
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.
Females tend to be fuller and
heavier than the males.
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.

at night. Hybrid: The progeny of two individuals
belonging to different species; the progeny of two individuals
belonging to different subspecies of the same species
