Sterbai’s Corydoras – Cuboid Nature Aquarium

Sterbai’s Corydoras

Sterbai’s Corydoras(Corydoras sterbai) is widely considered one of the most beautiful corydoras in the hobby — and one of the most sought-after. The dark body is covered in a dense pattern of white to cream spots that create an intricate leopard-like pattern, while the pectoral fins display vivid orange coloration that is unique among corydoras. Named for German ichthyologist Dr. Günther Sterba.

Feed near the substrate at lights-out.

Native to the upper Rio Guaporé basin on the Brazil-Bolivia border, Sterbai’s Corydoras inhabits slow-moving, warm, slightly acidic to neutral streams with sandy substrate and leaf litter. In the aquarium it thrives at slightly warmer temperatures than most corydoras — an important consideration when choosing tankmates. It pairs naturally with discus and other warm-water species.

Keep in groups of at least six — this is not optional for Corydoras. In the wild these fish occur in schools of dozens to hundreds. A lone Corydoras or a group of fewer than six is a stressed fish that stays hidden, refuses food, and lives a shortened life. In a proper group they are bold, constantly active, and endlessly entertaining to watch as they forage together across the bottom of the aquarium.

Corydoras are highly sensitive to substrate quality — fine sand is strongly preferred over gravel, as rough substrates damage the delicate barbels they use to forage. Regular partial water changes and pristine water quality are essential, as all Corydoras are sensitive to nitrites and dissolved waste. Sand substrate, gentle flow, and shaded areas with driftwood or plants will keep this species at its happiest and most active.
