Relevant Information:

Scleromystax salmacis, has colouration similar to that of S. macropterus, differing from that species mainly by the absence of a black spot on the base of the median caudal-fin rays, and transverse blotches along the body more irregular than those in S. macropterus. In addition to differences in colouration and external and osteological characters, the new species differs from S. barbatus and S. prionotos by its more rounded snout. The new taxon is also distinguished from its congeners by the presence of a single perforated dorsolateral body plate, similar to the condition found in some Aspidoras species, orientation of the ventral keel of the scapulocoracoid, and by the absence of sexually dimorphic features. Aquarium Care: 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. Remarks: In this genus the males can be somewhat territorial when in breeding mode.
