Scientific NameCorydoras septentrionalis  Gosline, 1940
Common NamesNorthern Longnose Cory
Panzerwels (Germany)
Type LocalityRío Piña, 6 km north of Maturín, 9°45'N, 63°10'W, R. Guarapiché system, Monagas, Venezuela.

EtymologyCory = 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. From the Latin septentrionalis meaning northern, alluding to the fact that this fish comes from northern South America.

Size 60mm or 2.4" SL. Find near, nearer or same sized spp.
IdentificationCorydoras 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 long-snouted species. The caudal fin rays are banded in brown and white, forming six or seven transverse rows.
SexingAs with all Corydoras, the females are ultimately larger and noticeably wider when viewed from above.

FeedingDry, frozen, and live foods.
FurnitureA dry season tank should have a leaf litter substrate with some pieces of driftwood. The water can be medium hard with a neutral pH and up to 82F. A rainy season biotope should have a sand and gravel substrate with driftwood pieces and a few larger stones that form caves. The water should be soft and cool at about 75F. In Cano Santo Domingo, Cojedes State, Venezuela the authors collected these Corydoras alongside C. aeneus ''black'', C. habrosus, Otocinclus vittatus, Hypoptopoma, Hypostomus plecostomus, Ochmacanthus, and Bunocephalus amaurus. Further south, this species appears alongside C. osteocarus.
CompatibilityThese fish get along with anything not large enough to eat them.
Suggested TankmatesSmall to medium-sized tetras (such as the Diamond Tetra), dwarf cichlids and hatchet fish are good additions. Generally the fish will mix well with most community tank citizens. Keep in groups of at least six.
