Pygmay Corydoras

The Pygmy Corydoras, also known as Corydoras pygmaeus, is a tiny, peaceful bottom-dwelling catfish that reaches a maximum size of 3 cm. Often confused with Corydoras hastatus or Corydoras habrosus, it can be distinguished by the stripe running down its body. Females are slightly larger and rounder than males, especially when carrying eggs. Pygmy Corydoras are perfect for nano and community aquariums.
