Sterbai Corydoras
Corydoras sterbai · also called sterbai cory, sterba's corydoras
Sifting through warm river sand with fine white speckling across a dark body and a flash of orange along each pectoral fin, a sterbai corydoras thrives in conditions that would trouble most of its cooler-water relatives, making it a natural companion for heat-loving fish like discus.
Overview
The sterbai corydoras, Corydoras sterbai, is a small, socially inclined bottom-dwelling catfish native to warm river habitat within the upper Rio Guapore basin of Brazil and Bolivia. Its fine white speckling against a dark body, vivid orange pectoral fins, and unusual tolerance for warm water make it one of the most sought-after corydoras species for keepers wanting to house bottom-dwelling catfish alongside warmth-loving fish.
The corydoras that can handle the heat
Where most corydoras species prefer cooler, more moderate water temperatures, the sterbai corydoras stands apart in its tolerance for consistently warm conditions, a trait rooted in the naturally warmer rivers of its native range and one that has made it especially popular among discus keepers.
Status
Least Concern, remaining present across suitable river habitat within the upper Rio Guapore basin of Brazil and Bolivia.
Sterbai Corydoras: common questions
Why is the sterbai corydoras often paired with discus?
This species tolerates noticeably warmer water temperatures than most other corydoras species, making it one of the few members of the group well suited to sharing a tank with warmth-loving fish such as discus, which require consistently warm conditions that most other corydoras cannot handle long-term.
How can you identify a sterbai corydoras?
This species has a dark brown to black body covered in fine white or cream speckling, combined with notably vivid orange-red colouring across the leading edge of the pectoral fins, a combination that helps distinguish it from other similarly sized corydoras species.
Should sterbai corydoras be kept alone or in groups?
This species is a social bottom-dweller that lives and forages in groups, with individuals kept alone or in very small numbers becoming noticeably withdrawn, less active, and less likely to display natural foraging behaviour.
Where does the sterbai corydoras come from?
This species is native to warm river habitat within the upper Rio Guapore basin of Brazil and Bolivia, a warmer environment than that of many other corydoras species, which helps explain its unusual tolerance for higher aquarium temperatures.
