Description

The bronze corydoras is an armoured catfish (Callichthyidae) from northern and central South America. The species has a stocky body armoured with two rows of bony plates, a bronze-green to coppery sheen and barbels around the inferior mouth. It lives mainly in calm, shallow waters with a soft bottom, but also in flowing water, and gulps air at the surface that takes up oxygen in the gut. As an omnivore it roots in the bottom for worms, insect larvae and organic material. It is a very popular aquarium fish. The stout pectoral fin spines can give a painful puncture wound when handled.
