is one of the most striking members of what we call
in the hobby, 'Driftwood Cats'. There are a few different
body markings in this species and they have been arriving
in the aquatic outlets in the U.K. now over the last
being as they are, are very secretive and if you want
to see your fish in a community setup these catfish
are not for you, but in saying that they are inoffensive
and as long as you haven't small fry in the aquarium
you can keep them with medium sized fish. You can of
course enjoy them at dusk when the lights are off in
your tank and your room lights are dimmed. I have had
success in bringing this species out when the tank light
is on, how do I do that? with frozen bloodworm and it
is a treat to see them circling around the bottom hoovering
them up until they get so bloated they just sit motionless
for what seems like ages, taking a rest to get their
These little catfish inhabit large rivers where the
water is swift, preferring littoral zones adjacent to
the shoreline over hard, sandy bottoms devoid of vegetation.
This factsheet has been updated (September 2019) to
facilitate the change in the genus name to Duringlanis
from Centromochlus. Just recently (September
2019)due to earlier work carried
out by Steven Grant (2015) a new paper was released
by Bárbara B. Calegariet
al whereas this species C. altae and C.
romani were reclassified to a new genus, Duringlanis.As stated in this paper some species treated
as Tatia and Centromochlus are assigned
to genera that were not previously recognised as valid.

Body naked and relatively short
head. Surface of head and the nuchal region (except
the orbits and the interorbital fontanel) are covered
with bony plates.The nuchal plate extends to and beyond
the base of the dorsal fin spine, and the horns of
the nuchal plate are curved downward and outward.
The eyes are moderately large and are covered with
Whitish base colour with black
irregular reticulated pattern. All fins clear.
Care & Compatability
Keeping this species is not
too much of a problem as long as the water is kept
clean and not too alkaline with a p.H.of between 6.5
and 7.0. They do like a planted aquarium where they
like to hide during the day. They also make a good
show fish if showing your fish at shows is your forte,
as they usually deport well in a show tank.
Internal fertilisation with
the eggs deposited 24-48 hours later. Also a report
on Tatia creutzbergi, (Tatia gyrina)
with them placing their adhesive eggs on the underside
of wood with no broodcare after the event. A few members
of the Auchenipteridae family have been spawned
in the hobby with a successful breeding and raising
of the young of Trachelyichthys decaradiatus

Area Catfish Group (now the Catfish
The anal fin is
the key to the sexual dimorphism of this genus, if
you think of the male and female of most livebearer
fish (Goodeidae family) and you will not be
too far away with this assumption. As you can see
above the female has a normal anal fin but the males
are modified into a copulatory organ with the first
and second ray thickened and longer, it is thought
that the male uses this to clasp the female during
the spawning embrace.
In its native habitat they
feed on insects, mostly ants, beetles, and mayflies
and in the aquarium they will eat anything given such
as frozen bloodworm which they will come out of hiding
to feed on, catfish tablets, daphnia, white worm (sparingly)
and any other worm-like foods.
