Relevant Information:

One of the species in the so called "Elegans group" and it can be difficult at times to be able to identify to species. The problem stemmed from the first description which did not mention any characteristics. The first specimens captured were very small and the Holotype was only 23mm from the Surinam-Brokopondo, Surinam River system. There was also 6 paratypes which were smaller and are housed in the RMNH (4) and the ZMA (2). This Cory is not very common in the hobby. Aquarium Care: As per this genus, housed with non aggressive species or a species tank. Buy at least 6 as they will stay together in the tank which will make them feel more comfortable in their surroundings. Diet: As per this genus with good quality flake food, tablet, frozen and small worm foods. Remarks: The thumbnail image depicted is a wild specimen which was captured by the image contributor in the Gran Rio a river in Suriname and is considered to be the true C. nanus.
