Corydoras pygmaeus — Pygmy Cory

The Pygmy Cory is one of the smallest corydoras species, reaching only about 3 cm, and is notable for spending time swimming in the mid-water column rather than strictly bottom-dwelling. It has a slender body with a bold dark lateral stripe. It is a peaceful, schooling fish that thrives in planted tanks with soft, slightly acidic water.
