Sterbai Cory Behavior
The Sterbai Cory is a peaceful, social fish that does best in a group of at least six fish. They enjoy the company of their own kind and will often shoal together in the wild. These little guys are shy by nature, so they will appreciate plenty of hiding places in your aquarium. The more Corydoras you have in your tank, the more likely they are to come out and play.
Sterbai Corys are mostly active at night when it's dark. This is when they will do the majority of their foraging for food. During the day, they like to rest in small groups beneath plants or decorations, often close to the aquarium glass.
Sterbai Corydoras are air-breathing fish that can breathe air if necessary. This allows the fish to survive in an oxygen-depleted environment since they may breathe air if necessary.
When your Corydoras swim upwards towards the surface to take a breath of air, you'll see them do it in an aquarium setting. So, although these fish are benthic (bottom-dwelling), they do require some access to the surface. Although this is a natural reaction and not a cause for immediate concern, frequent visits to the surface by the fish might be an indication of poor water quality.
Sterbai Corys spend the majority of their day resting on the aquarium floor in shaded, protected nooks beneath plants or decorations. This adorable little fish will be ruffling around on the tank bottom searching for food between rests.
Your Corydoras Sterbai can "blink" their eyes, and you can see it if you look closely. Fish do not have eyelids, so they cannot close their eyes in the same way that humans can. What your Sterbai Corydoras is actually doing is tilting its eye down to check out what's available to eat on the aquarium floor!
