Sterba’s Corydoras, scientifically known as Corydoras sterbai, is a small freshwater catfish that is often found in home aquariums.
It comes from South America, specifically the area around the Guaporé River between Bolivia and Brazil.
They are shoaling fish and like to be with their own kind. So it’s best to keep them in groups of five or more.
Their natural habitat consists of soft, acidic water.
However, they are hardy and can adapt to different water conditions when raised in tanks.
Although hardy, Sterba’s corydoras can’t handle high levels of nitrates. These fish aren’t algae-eaters like some catfish species.
However, they can be quite useful in maintaining a clean tank as they feed on leftover food and debris found at the bottom of the water.
