Pygmy Corydora

Pygmy Corydora (Corydoras pygmaeus)

The Pygmy Corydora is a charming nano catfish prized for its tiny size, peaceful temperament, and unique schooling behavior. Native to the slow-moving tributaries of the Amazon Basin in South America, this miniature species features a sleek silver body accented by a bold horizontal black stripe, giving it a simple yet elegant appearance.

Unlike many other Corydoras species that spend most of their time on the substrate, Pygmy Corydoras frequently swim in the middle levels of the aquarium, often schooling together in tight groups. They thrive when kept in groups of six or more and are most comfortable in planted aquariums with soft substrates, driftwood, and plenty of cover. Their active nature and social behavior make them a fascinating addition to nano and community aquariums.

Pygmy Corydoras are hardy, peaceful, and highly compatible with other small, non-aggressive fish. Their small size allows them to thrive in nano aquariums, while their constant activity and schooling behavior add movement and personality to the tank. Their gentle nature and ease of care have made them a favorite among aquascaping enthusiasts and community fish keepers alike.
