Scientific Name Corydoras bicolor  Nijssen & Isbrücker, 1967
Common Name
Type Locality Sipaliwini River near border with Brazil, Corantijn River system, Paru Savanna, Nickerie, Suriname.
Pronunciation Kory DOOR ass - bi kol orr
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.

Size 45mm 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.
Sexing Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
General Remarks This is a rare species in the hobby. It has been imported a few times but only by travelling aquarists. It is closely related to Corydoras burgessi and Corydoras melanistius from Brazil.
