The sixray corydoras (Corydoras pauciradiatus) [3] or false corydoras is a tropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in inland waters in South America, and is found in the upper Araguaia River basin in Brazil.
The fish will grow in length up to 2.9 centimetres (1.1 inches). It lives in a tropical climate in water with a pH of 6.0 – 7.2, a water hardness of 12 dGH, and a temperature range of 22–25 °C (72–77 °F). It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs.
The sixray corydoras is of commercial importance in the aquarium trade industry.
Callichthyidae is a family of catfishes, called armored catfishes due to the two rows of bony plates along the lengths of their bodies. It contains some of the most popular freshwater aquarium fish, such as many species in the genus Corydoras.
Corydoras is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae. The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where Corydoras is not present. Corydoras species are distributed in South America where they can be found from the east of the Andes to the Atlantic coast, from Trinidad to the Río de la Plata drainage in northern Argentina. Species assigned to Corydoras display a broad diversity of body shapes and coloration. Corydoras are small fish, ranging from 2.5 to 12 cm in SL., and are protected from predators by their body armor and by their sharp, typically venomous spines.
The bronze corydoras, 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 by Theodore Gill in 1858 and has historically also been referred to as Callichthys aeneus.
