Males develop an extended dorsal
fin and pectoral spines and sexually mature males
sport bristles on the cheeks. Similar markings as
Becoming rare now in exports. As with all Scleromystax
species they will fare better in cooler temperatures.
The genus Scleromystax belongs to lineage
3 and 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).
Aquarium Care: Sometimes the males
can get aggressive to other males so maybe one male
to a group may be the best way to go if there are
conflicts in the aquarium. 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.
Diet: 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
