Corydoras septentrionalis • Callichthyidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Corydoras septentrionalis** Gosline, 1940
Common Name(s)	Northern Longnose Cory
Type Locality	Río Piña, 6 km north of Maturín, 9°45'N, 63°10'W, R. Guarapiché system, Monagas, Venezuela.
Pronunciation	Kory DOOR ass - Sep TEN tree on al iss
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. From the Latin septentrionalis meaning northern, alluding to the fact that this fish comes from northern South America.
Species Information
Size	60mm (2.4") 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 long-snouted species. The caudal fin rays are banded in brown and white, forming six or seven transverse rows.
Sexing	As with all Corydoras, the females are ultimately larger and noticeably wider when viewed from above.
Habitat Information
Distribution	A common Corydoras in the piedmont and northern Llanos tributaries of the Orinoco system of Venezuela. Its range may also extend into Colombia. Orinoco (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	6.0 - 7.5
Temperature	22.0-26.0°C or 71.6-78.8°F (Show others within this range)
Other Parameters	A very adaptable Corydoras that requires no special water conditions.
Husbandry Information
Feeding	Dry, frozen, and live foods.
Furniture	A 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.
Compatibility	These fish get along with anything not large enough to eat them.
Suggested Tankmates	Small 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.
Breeding	Unreported.
