Etymology Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. Greek Mythology, After Narkissos, son of the Greek river god Kephissus. See catfish of the month article for a more detailed discussion.

Size 65mm or 2.6" SL. Find near, nearer or same sized spp.
Identification Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

C. narcissus is the long snouted ''version'' of C. arcuatus and is readily identifiable by this characteristic. Two species exist that are commonly sold as C. narcissus. The real one is longer (the ratio of body height to length being significantly different), has a more pronounced concave head and a slightly darker basic colouration. The other, shorter fish is C. bethanae.
Sexing Female larger and stouter especially when viewed from above. Male has more pointed fin tips.

Hop to next section Husbandry Information
Feeding All prepared foods and frozen foods especially bloodworm and brineshrimp. Adults gorge on chopped mussel.
Furniture A little shading helps makes the fish feel at home. Sandy substrate brings out the best in these fish although because of the large size of the adult fish small pea gravel can also be employed.
Compatibility Peaceful and not anti-social with other catfish excepting occasional quarrels with it's own species. Youngsters appear sociable to each other but become quarrelsome with age. Rival adult males may bully each other to death if kept in too small an aquarium.
Suggested Tankmates South American dwarf Cichlids, larger Characins such as Silver Dollars (Metynnis spp.) are ideal although medium-sized Central American Cichlids and Asian anabantoids are good alternatives if you are not a biotope purist.
Breeding Unknown
