General information – The Corydoras sterbai is one of the most

popular fish from the Callichthyidae family. It has a beautiful silver

backdrop with rows of black spots. Like all Corydoras species, this

species can diffuse oxygen using the posterior part of the gut, so

swimming up to the surface and gasping for air, then immediately

diving back to the bottom, it is normal and should not be considered

as a sign of fault. It also, like other Corydoras species, tend to "wink"

by rolling it's eyes downwards, a characteristic considered as funny

and makes these fish more loveable
