he topic for this months factsheet of June 2023 is
from the Pseudopimelodidae family and the Giant Bumblebee
Catfish, aka Pseudopimelodus
This is a pretty patterned catfish that should only
be kept with the same size or larger tank mates as
it can be predatory at night. The common name "Giant"
may be a misnomer growing to 24.5cm. (9¾ins)
standard length (S.L. Standard length as measured
from the snout to the caudal peduncle) and not growing
as large as the large pims we see in the hobby, but
it can still pack a punch at feeding times.
Pseudopimelodus now includes six species
P. atricaudus, P. bufonius, P.
charus, P. magnus, P. mangurus,
and P. schultzi, although this number is
expected to increase, given the high genetic divergence
observed among its members (Rangel-Medrano, Ortega-Lara
& Márquez, 2020).

This species is
very wide spread throughout the
rivers of northeastern South America from the Lake
Maracaibo basin to eastern Brazil and the Magdalena
and Cauca River basins Colombia, with probably a few
undescribed species mixed in with that scenario and
the type locality of French
Guiana and the Guiana Shield may be restricted
to P. bufonius in the future (Grant, S. 2021).

basin to eastern Brazil and Magdalena and Cauca

Cayenne, French Guiana.
As they get older
in the aquarium they will attack conspecifics
so best to keep a single individual to mitagate
the aggresion. Tank mates could be larger
Chiclids and Hypostomus sp.or large
tetra's such as "Silver Dollars".
Pseudopimelodidae, in general, are a group
of bottom fish occurring mainly in lotic regions,
such as rivers and creeks, sheltered in trunks,
roots, rocks, leaf litter packs and macrophytes.
It is an ambush predator, feeding on small
fish, insects, and crustaceans.
Despite the limited
information available on this species, it
is assessed as Least Concern due to its wide
range (IUCN 2020).
sub-family of Pimelodidae, Pseudopimelodinae,
is now considered a full family status of
Pseudopimelodidae and is of course closely
related to the Pimelodidae family.
America:Rivers of northeastern South America from
Lake Maracaibo basin to eastern Brazil and Magdalena
and Cauca River basins, Colombia. Type locality:
Cayenne, French Guiana.
Caudal fin forked; adpressed
dorsal fin reaching no more than about half way the
distance between dorsal and adipose fins; pectoral
fins with 7 rays.
The brown and orange bands
on the body reminds one of the
colourings of the Bumblebee,
hence the common name.
Care & Compatibility
predatory so tank mates would have to be of similar
size or larger. Give this species plenty of hiding
places to keep it happy in its surroundings.
It will need a large tank and regular water changes
to keep this catfish in good health.
Males seem to
be more slender and have a lighter all over colouration
from the females.
