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, often kept as an aquarium fish.
They are found in shallow waters with soft bottoms that can sometimes be heavily polluted by mud, but it also inhabits running waters. Like most members of the genus Corydoras, these catfish have a unique method of coping with the low oxygen content that prevails in such polluted environments. They rapidly come to the surface of the water and draw air in through their mouth. This air is then absorbed through the wall of the intestine and any surplus air is expelled through the vent. It typically stays in schools of 20 to 30 individuals. It feeds on worms, benthic crustaceans, insects, and plant matter.
