Scientific Name Corydoras osteocarus  Böhlke, 1951
Common Names C060, Panzerwels (Germany)
Type Locality San Fernando de Atabapo, 4°03'N, 67°45'W, where Río Atabapo empties into Río Orinoco, Amazonas, Venezuela.
Pronunciation Kory DOOR ass - oss tee oh CARR uss
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. Although all Corydoras have a 'helmet', the species name comes from the Greek for bone and head. Literally the bonehead Cory!

Size 46mm or 1.8" 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.

A slender are slightly elongated, round head Corydoras; the fish shows more spots on the front half of the body behind the gills and these diminish past the posterior edge of the dorsal fin. A black band runs vertically down through the caudal peduncle.
Sexing Females are larger and fuller especially when viewed from above. Males are more slender and have more pointed ends to the paired fins than the females.
General Remarks The first three pictures of fish above were taken in Venezeula and are of fishes collected very close to the type locality.

Jump to next section Husbandry Information
Feeding Blood and glass worms (red and white mosquito larvae) as well as sinking pellets.
Furniture Shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required. Ideally substrate should be sand, but rounded gravel will suffice.
Compatibility A perfect citizen.
Suggested Tankmates All Corydoras should be kept in groups of at least 6 of the same species. Otherwise compatible with most other types of fish that are reasonably peaceful, as long as they don't see a Corydoras as a snack.
Breeding Reportedly easy with well conditioned adults and a drop in water temperature. Spawning activity is typically frenzied. No information at present on rearing fry, but it should follow the pattern for similarly sized species.
Breeding Reports There is but a single breeding report, read it here.
