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 California River.
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.
Hoplisoma panda, formerly known as Corydoras panda, is a species of catfish belonging to the genus Hoplisoma, of the family Callichthyidae, and is a native member of the riverine fauna of South America. It is found in Peru and Ecuador, most notably in the Huánuco region, where it inhabits the Río Aquas, the Río Amarillae, a tributary of the Río Pachitea, and the Río Ucayali river system. The species was first collected by Randolph H. Richards in 1968, and was named Corydoras panda by Nijssen and Isbrücker in 1971. The specific name is an allusion to the appearance of the fish, which possesses large black patches surrounding the eyes, reminiscent of those found on the giant panda. Accordingly, the common names for this fish are panda corydoras,panda catfish, and panda cory.
Aspidoras is a genus of catfishes of the family Callichthyidae from Brazil.
The blacktop corydoras is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It originates in inland waters in South America, and is found in the Amazon River basin in Ecuador and Northern Peru. It was described by Edward Drinker Cope in 1872.

The pink corydoras is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It originates in inland waters in South America, and is found in the Meta River basin in Colombia. A maximum body length of 4.2 cm has been reported.

The sailfin corydoras, bigfin corydoras, or largefin corydoras is a subtropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in coastal rivers in South America, and is found from São Paulo to Santa Catarina, Brazil and some upper Paraná River tributaries. It was originally described, under the name Corydoras macropterus, by C. Tate Regan in 1913.
Corydoras narcissus, commonly known as the long nosed arched cory, is a freshwater fish belonging to the Corydoradinae subfamily of the family Callichthyidae, native to the Madeira and Purus river basins in Amazonian Brazil. It has a longer, more concave ("saddle-shaped") nose, but its color pattern resembles that also seen in a few other Corydoras species from the western Amazon basin, as well as Brachyrhamdia thayeria; they all have spiny fins with a painful but not dangerous venom and their similarity is an example of Müllerian mimicry. C. narcissus generally is an uncommon species in its range.
The blue corydoras or Natterer's catfish is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It originates in coastal rivers in South America, and is found in the Brazil from Espírito Santo to Paraná. It is named for Johann Natterer, its discoverer.

Scleromystax is a genus of fish in the family Callichthyidae endemic to small tributaries from several coastal river basins draining the southern and southeastern regions in Brazil. Most of the species of Scleromystax are highly sexually dimorphic; males have developed odontodes inserted in fleshy papillae on the preopercular-opercular region and the dorsal and pectoral fins are 2–3 times as long as those of females. S. salmacis is an exception, as its sexually dimorphic features are subtle and non-remarkable.
