I recently added these stunning Black Corydoras to my tank, and I couldn’t be happier! After a week of observing their behavior, I can honestly say these little catfish have brought so much joy and activity to my aquarium. Each one is about 2-3 cm and has a captivating black-and-white pattern that really stands out against the substrate.
What impressed me the most is how social they are! They dart around the tank, often sticking together, which is a joy to watch. They’ve quickly become my favorite community fish, especially since they’re peaceful and get along well with my other tropical fish.
Compared to other catfish I’ve kept, these Corys are much more active and engaging, making them a fantastic choice for any aquarium enthusiast. Just a minor note: they do appreciate a sandy substrate to sift through, which can be a little tricky if you’re used to gravel.
Overall, I highly recommend these Black Corydoras for anyone looking to enhance their aquarium. They’re perfect for beginners and experienced fish keepers alike. Plus, they arrived in excellent condition and adapted to my tank within hours. I will definitely be purchasing more in the future!
