cleromystax lacerdai was described by Harro
Hieronimus in 1995 as Corydoras lacardai from
the Rio Terre Firmeand subsequent collections
thereafter have found this species also in the Rio
Cahy, in Prado and the Rio Pardo in Canavieiras all
in the Bahia state. Before it was described it was
given the C-number of C015.
The shame of this
lovely small Scleromystax species is that
it is now endangered in the wild and we may not see
them at all in the future due to deforestisation in
their local habitats, that is why we need to keep
it alive in the hobby for future generations. The
remaining populations, if there is any, are located
between the cities of Canavieras and Ilheus in Bahia.
There is also another species from the Bahia State
that also resembles S. lacardai.
4 weeks old
The genus Scleromystax
belongs to lineage 3 and are more closely related
to the Aspidoras genera from lineage 2 rather
than the Corydoras. If there was a revision
carried out on the Corydoradinae in the future they
would remain so, with the designated type species
S. barbatus (Günther, 1864).
Brazil, Ribeira da Terra Firme River, Bahia.
As this is a small species
of Scleromystax you can house them in smaller
tanks. The males do not fight or quarrel as do the
larger members of this genera.
Baianinho Cory, C015
South America:Brazil; Ribeira da Terra Firme River, Bahia.
Male: 5.0cm (2ins) Female:
Head shape elongated with extended
snout. A wide dark band extends along the position
of the spinal cord and reaches almost to the ridge
on the back on males with the females having this
band broken up into an uneven bar pattern. Another
band extends along the ridge of the back from the
front of the dorsal fin to the base of the caudal
fin. There is a thin band in the belly region which
runs from the pectoral fin to the adipose fin. A further
band extends from the eye to the tip of the snout.
The body is sandy coloured.
The dorsal fin rays are banded black and white, and
the spine and the first ray have a black colouration.
The dark bands along the body are coloured black in
specimens in good condition plus when in breeding
Care & Compatibility
As with most members of the
Callichthyidaethey are peaceful.
The Scleromystax genera are good additions
to "cool water" aquarium set ups with maybe
other cool water fish such as White Cloud Mountain
Minnows and other fish that are comfortable with a
temperature around the 70°f (21.5°c) mark.
Other "cool water" species such as small
barbs and the aforementioned White Cloud Mountain
Minnows would be good additions to your aquarium,
but if you are lucky enough to purchase S. lacardai
I would keep them on their own in a small aquarium
for breeding purposes.
The first spawning
of S. lacardai was successfully carried out
in 1998 by fellow Scottish catfish aquarist Jim Makin
and the authors S. lacerdai parents came
from this line. The author has also bred this species
and at present is keeping them going again. They breed
in the usual Corydoradinae fashion with t-positioning
and laying their eggs high up in the aquarium walls.
The fry have been fed firstly on Liquifry for egglayers
then on to micro worm and then to crushed flake carried
out using a pestle and mortice which can crush the
flake to a fine powder. For further reading material
on breeding the various members of the Corydoradinae
sub family go to the breeding section of the website
A wide dark band
extends along the position of the spinal cord and
reaches almost to the ridge on the back on males with
the females having this band broken up into an uneven
bar pattern. The females also grow larger and have
a wider girth.
As with other members of the
Corydoradinae they relish tablet and good quality
flake food with frozen bloodworm a firm favourite.
They are also keen on chopped earthworms and other
worm foods such as white worm used sparingly, and
Fleshy finlike projection without rays, behind the
rayed dorsal fin. Caudal fin: The tail. Dorsal fin:The
primary rayed fin(s) on top of the body. Pectoral fins: The paired fins just
behind the head.
From the Greek "sclero" meaning hard and
the Latin "mystax" meaning moustache. lacardai: Dedicated to Mr.
