Sterbai Cory ~ Corydoras sterbai

The Sterbai Cory is a beloved bottom-dwelling catfish known for its striking pattern of white spots over a dark body, contrasted by bold, mask-like facial markings and bright orange pectoral fin bases. Native to the warm, slow-moving tributaries of the Guaporé River region in Brazil and Bolivia, this species is prized for its peaceful temperament, endearing social behaviors, and constant foraging activity. Its ability to thrive in community setups, along with its distinctive appearance, makes the Sterbai Cory one of the most popular Corydoras species in the aquarium hobby.

• Size: 2.5-3 inches

• Lifespan: 5-10 years

• Temperament: Peaceful, social

• Group/Solitary: Must be kept in groups of 6+

• Food: Sinking pellets, wafers, frozen/live foods such as bloodworms, brine shrimp, and tubifex

• Water Requirements: 72-82°F, pH 6.0-7.8, soft to moderate hardness

Sterbai Corydoras thrive in well-planted aquariums with fine, smooth substrates such as sand, which allow them to exhibit natural sifting behavior without risking injury to their delicate barbels. These fish are highly social and display their best activity and confidence when kept in groups of six or more, often moving together as a tight unit while they forage. They mix seamlessly with peaceful community fish and are tolerant of slightly warmer temperatures, making them suitable companions for species like discus and many types of tetras. A diet of high-quality sinking foods supplemented with live or frozen treats helps maintain their robust health and encourage breeding behavior. Clean water, gentle flow, and shaded areas contribute to long-term well-being.

In the wild, Sterbai Corys inhabit slow-moving, warm, and often tannin-rich waters with sandy or muddy bottoms covered in leaf litter. These environments provide abundant microinvertebrates and organic debris that the fish sift through using their sensitive barbels. Their spotted pattern and subtle armoring help them blend into the dappled shadows of roots and fallen leaves, offering protection from predators while they forage.

Fun Fact: Sterbai Corys can produce faint clicking sounds during social interactions or excitement, a behavior created by special muscles near their swim bladder and often heard during feeding time or courtship.
