Bronze corydoras

The bronze corydoras (Corydoras aeneus), also known as the green corydoras, bronze catfish, lightspot corydoras or wavy catfish, is a species of freshwater fish in the armored catfish family, Callichthyidae, often kept as an aquarium fish. It is widely distributed in South America on the eastern side of the Andes, from Colombia and Trinidad to the Río de la Plata basin; however, as presently defined it is a species complex and a taxonomic review is necessary. It was originally described as Hoplosoma aeneum (based on a specimen from Trinidad) by Theodore Gill in 1858 and has historically also been referred to as Callichthys aeneus.
