Description:
Dorsal spines (total): 2; Dorsal soft rays (total):
7; Anal soft rays: 12 - 13; Vertebrae: 46. Distinguished
from its congeners by a unique combination of the
following characters: head length 28.1-29.6% SL, head
depth 11.9-14.3% SL, depth of the caudal peduncle
8.8-9.9% SL, eye diameter 13.8-15% HL. Aquarium
Care: As with most of the genus, H. punctatus
can become a pretty nasty character in your fish
tanks and if housed with other fish can be lethal.
Cichlids such as the Pikes from the Crenichla
genus that can look after themselves would be
the best bet for other tankmates. If kept with other
fish they will have to be able to look after themselves.
Diet:Whilst this catfish
is best described as a predator/carnivore in its natural
habitat feedings of fish, insects, shrimps and other
crustaceans, in captivity this catfish will feed on
mussels, prawns, pieces of fish, earthworms and will
even take prepared foods such as catfish pellets.
Etymology: The genus name Hemibagrus:
Hemi- half; bagrus- from 'bagre',
a South American name for a catfish, but is only used
for African and Asian species. The
specific name punctatus: from
the Latin punctatus = 'spotted'. Remarks:
Hemibagrus punctatus was known from three
locations from which the species has not been recorded
since late 1990s. Subsequent and recent surveys in
the rivers have not recorded this species thereby
suggesting a drastic decline of close to 100% due
to habitat loss and other threats that are not yet
clearly understood. The species' identity may need
further scrutiny in some locations it has been reported
from, and in addition the confirmed locations need
to be surveyed thoroughly before its status can be
assessed as extinct. It is therefore presently assessed
as Critically Endangered (possibly extinct), (Raghavan,
R. & Ali, A. 2011).
