Relevant Information:

Males develop an extended dorsal fin and pectoral spines and sexually mature males sport bristles on the cheeks. Similar markings as Corydoras paleatus. 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 of Scleromystax 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 Callichthyidae they 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.
