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. Inhabits rivers, beels,
canals and ponds and prefers soft substrates where
it lies concealed in the soft mire of the river bed.
It depends upon this concealment for protection and
will not even move when it is touched lightly. Lies
quietly on the bottom until some prey comes along.
Apparently a worm-like appendix at the fringe of the
mouth is used to attract prey. Fairly common in catches,
but is not eaten perhaps due to its ugly appearance.
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 tank mates 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.
