Those smaller amounts are more likely they will even shoal with members of different species but again this is not as typical corydoras can be identified by the three pairs of barbells found on their faces knees act as sensors to aid in finding food on the floor of the water column. They’re kind of like fingers but on their faces, you could sort of correlating them to cat whiskers even these barbells are sensitive to sharp or harsh substrates.

Some species of Cory catfish display quite the spectacle the male and the female form what is commonly known as the T position in which a female will drink the male sperm straight from the source.

Cory catfish facts

It’s been commonly believed that corydoras wink at their owners though this is a bit of a misconception. Cory catfish are not able to close their eyes but they can roll their eyes downward which causes the pupil and iris to disappear from the view of the observant keeper this gives the illusion of the fish winking their eye at their owner but well they can’t really offer flirtatious gestures.

The fact that owners have even observed this eye-rolling behavior is in and of itself pretty awesome most catfish are nocturnal thus becoming more active at night. Cory catfish are diurnal like us which gives us ample opportunity to watch their fun and fishy antics one other cool fact about corydoras is that they breathe air while watching them. An owner may catch sight of one quickly swimming to the surface of the tank and then justice with ly returning to the bottom the is because their gills are not designed to take in enough oxygen from the surrounding water so they have to do this from time to time to quite literally catch their breath.
