Pygmy Corydoras – Adorable Miniature Freshwater Catfish
The Pygmy Corydoras (Corydoras pygmaeus) is a charming miniature freshwater catfish admired for its tiny size, sleek silver body, and distinctive black horizontal stripe.
Unlike many traditional Corydoras species, Pygmy Corydoras frequently swim in the middle levels of the aquarium, displaying fascinating schooling behaviour. Their peaceful temperament and playful personality make them a wonderful addition to planted nano aquariums.
These delightful little catfish thrive in groups, creating an entertaining display as they explore aquatic plants, driftwood, and open swimming areas. They prefer clean, stable water conditions, gentle filtration, and plenty of hiding places.
An excellent choice for aquarists seeking a peaceful, active, and adorable nano aquarium fish.
