The Duplicate Corydora is a peaceful and hardy freshwater catfish featuring a striking pattern of paired markings or mirrored spots along its body, giving it the “duplicate” appearance. Like other Corydoras, it is an active bottom-dweller that spends much of its time sifting through the substrate for leftover food and biofilm, helping keep the tank clean while adding charm and activity.
This species is easy to moderately easy to keep, suitable for beginners and experienced aquarists alike. Its calm temperament and schooling behavior make it ideal for community aquariums.
