I recently added Sterba’s Cory (Corydoras sterbai) to my community tank, and I couldn’t be happier! These little catfish are not only stunning with their unique patterns and bright colors but also super active and friendly. After about two months of keeping them, I’ve noticed how they tirelessly scavenge around the tank, keeping the substrate clean and interacting joyfully with my other fish. They are perfect for a community aquarium as they get along well with various species.
Compared to other cory species I’ve kept, the Sterbai are definitely more social and engaging; they seem to have a curious personality that keeps me entertained. I was a bit worried about their care requirements, but I’ve found them easy to maintain with a good diet of quality sinking pellets and occasional treats like bloodworms. Just a tip: make sure to provide some hiding spots and soft substrate since they love to burrow! If you’re looking for an aquarium fish that adds both beauty and activity, I wholeheartedly recommend these cory catfish. They truly bring joy to my tank and brighten my day!
