I recently added 2 Sterba’s Cory (Corydoras Sterbai) to my community aquarium, and I couldn’t be happier with my purchase! These little guys are just stunning, with their soft, graceful movements gliding across the substrate. After about two months in my tank, they’ve become the stars of the show. Their peaceful nature makes them perfect for beginners like me, and they really bring a lively touch to my setup without any hassle.

One of the features I adore is how they thrive in groups; they’re not just catfish, they’re social little creatures! I did notice they love to hide among the plants and decorations, which is something to consider if you have a more open tank. My only tiny complaint is that they can be a bit shy at first, but once they feel safe, they’re out and about! I’d highly recommend the Sterba’s Cory for anyone looking to enhance their aquarium with low-maintenance yet charming companions.
