Lives alongside Corydoras
white water and clearwater streams in the coastal
lowlands. The males do not sport the extended pectoral
and dorsal spines as do other members of this genera.
The females are wider in the girth when sexually mature,
the males are smaller. As with other species of Scleromystax,
will do better in cooler temperatures. Aquarium
Care: 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 grindal worm. Remarks:
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).
