Corydoras: Greek, kory = helmet + greek, doras = skin
Corydoras aeneus is probably the widest spread of all the Corydoras species, it is commercially bred in vast numbers in the far east and is probably available in every aquatic shop throughout the world. C aeneus also has a wide range of colour patterns, more commonly there is; the Bronze and Albino variety, but some newly found colour varieties are being found in the wild, which may in fact turn out to be separate species; C.cf aeneus (Black), C.cf aeneus (Peru green stripe) and C.cf aeneus (Peru gold stripe), to name some. C. aeneus should be kept on a substrate of rounded gravel, or preferably sand, as sharp gravel can erode their barbells, making them useless for breeding, especially the females. Even when keeping them on gravel or sand, the substrate needs to be kept clean as a build up of bacteria in the substrate will also erode their barbells. C. aeneus is a shoaling fish that needs the company of it's own species, and is better kept in groups of six or more.
Omnivore; live or frozen food, flake and pellet food are all eagerly accepted.
When Corydoras are kept in good condition, viewed from above females are usually broader than males, and looking at the fish from the side, females tend to be deeper and plumper looking than males. Females grow slightly larger than males.
Use a separate breeding aquarium with a sponge filter and a thin layer of sand for substrate. Introduce two well conditioned males and one well conditioned female after a small period of separation. Make a small water change using slightly cooler water to stimulate spawning.
The wild status of C. aeneus has not been evaluated.
