Corydoras bicolor • Callichthyidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Corydoras bicolor** Nijssen & Isbrücker, 1967
Common Name(s)	None
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.
Species Information
Size	45mm (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.
Habitat Information
Distribution	Coastal rivers of Suriname. Guyana Waters, Coastal Rivers of Guyanas, Suriname Coastal Rivers (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	4.6 - 7.4
Other Parameters	GH: 1 - 10 KH: 1 - 4 Conductivity: 10 - 250 Micro-Siemens
Husbandry Information
Feeding	Small crustaceans (Daphnia,Cyclops, Brine shrimp), worms (Tubifex, Grindal, Whiteworm, & chopped earth worm). Most commercial flake, tablet and granular foods accepted.
Furniture	Natural habitat: Sand substrate with leaf litter. Natural habitat is low in aquatic vegetation, overhanging vegetation.
Compatibility	A very peaceful species that will be happy in most community aquaria.
Suggested Tankmates	Avoid keeping them with aggressive species.
Breeding	Has been bred under aquarium conditions and follows the typical Corydoradinae 'T' mating ritual.
