Chaca bankenensis seems to be a little bit darker
in colouration than Chaca chaca and has
one less pectoral ray, 1/4 to 1/5 of C. chaca.
You can differentiate the difference between Chaca
burmensis and Chaca chaca by the number
and the size of the cirri along the inner edge
of the lower lip, C. chaca has 14+ and tends
to be relatively longer and/or thicker. Chaca burmensis
usually numbers around 10 or 11 small cirri,
and they don’t tend to have them near the corners
of the mouth. There seems to be two forms of this
species, Archipelagic and peninsular. Found in swamp
forest and streams with soft bottom, usually among
leaf litter and aquatic vegetation. Feeds on fish
and shrimp. Possesses a short dorsal spine which can
inflict painful wounds. Aquarium Care:
This catfish does not do a lot apart from sitting
very still buried in the substrate waiting for its
next meal and then engulfing its prey by opening its
very large mouth and basically creates a strong vacuum,
whereas the unlucky victim is drawn in to the gaping
hole!. It is a very hardy aquarium fish that will
do very well on a sand/leaf substrate where it can
bury itself with just its head showing and also a
landscape of rocks and caves. It is not your average
community tank fish so I would choose my tankmates
carefully for fear of them getting eaten as they will
consume fish half their size. Probably any species
of the African Synodontis would do fine and
for the upper layers you would do better with larger
shoaling fish such as Congo tetras, or larger barbs
i.e. Tinfoil Barbs. This would pre-empt a larger tank
to house the larger barbs or characins. If you can
make the space, a better idea would be a species tank
with 3 to 4 individuals, as they seem to coincide
peacefully with one another. Diet:
A feeding of earthworms and other meaty foods such
as feeder fish like young Tilapia sp. They
are said also to take tablet food when fully acclimatised.
