|Cat-eLog Data Sheet|
|Scientific Name||Corydoras duplicareus Sands, 1995|
|Type Locality||Rio Poranga, 8 km north of the Nobua oba, prior to where it joins a small trib. of the upper Negro R., Brazil.|
|Pronunciation||Kory DOOR ass - DOOP lee KARR ee 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. This specific epithet literally means from two(di=two) rivers(fluviatalis=from the river).|
- Shane's World Reproduction Breeding Corydoras duplicareus
|Size||55mm or 2.2" 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.
According to the description C. duplicareus has serrations on the posterior edge of the pectoral fin spine, whereas C. adolfoi does not. This of course is not easy to see in a normal aquarium. The best way to see if your fish have these serrations would be to place them into a shallow, preferably white, container and shine a light up from underneath. Then with the aid of a magnifying glass you should be able to see if there are any serrations or not. As a general rule C. duplicareus tends to be a little stockier than C. adolfoi and the black band is usually a little broader.
