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.
Lineage: 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 ofScleromystax
species 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
