Also called the Peppered Cat or Salt and Pepper Corydoras, the Peppered Corydoras is a popular choice among aquarium hobbyists. Peppered Corydoras are native to the lower Parana River basin and can also be found in the coastal rivers of Brazil, Argentina and Uruguay. These fish tend to inhabit rivers and tributaries as well as standing bodies of water such as small lakes and pools. Peppered Corydoras have silver or light brown bodies covered in black patches. Many specimens also exhibit black spotting or banding on the fins which are otherwise transparent. An albino form of this species can sometimes be found in pet stores.
