Pygmy Cory Catfish | Corydoras pygmaeus

The Pygmy Cory Catfish (Corydoras pygmaeus) is one of the smallest Corydoras species in the aquarium hobby. Known for its tiny size and active schooling behavior, this charming fish is perfect for nano aquariums and planted community tanks.

Unlike many other Corydoras species that stay strictly on the bottom, Pygmy Corys often swim in the middle levels of the aquarium, forming small schools that move gracefully through the water. Their slender body features a dark horizontal stripe running from the snout to the tail, giving them a clean and recognizable appearance.

Because of their peaceful nature and small size, Pygmy Cory Catfish are a favorite among aquascapers and nano aquarium enthusiasts.
