Julii Cory

The Julii Cory is often confused with the Three Stripe Cory but has a distinctive fine spotted pattern rather than stripes. These small, peaceful bottom-dwellers have a silver-grey body covered in tiny black dots with a distinctive pattern on their head. Native to Brazil, Julii Corys are active, social fish that prefer soft water and should be kept in schools. Their intricate pattern makes them one of the more attractive corydoras species.
