Sterbai Cory Blog

The Sterbai Cory, also known as Corydoras sterbai, is a peaceful and hardy freshwater catfish that is highly popular among aquarists for its distinctive appearance and calm temperament. Native to slow-moving rivers and tributaries in South America, this bottom-dwelling species is ideal for community tanks and planted aquariums.

Appearance and Coloration

Sterbai Corys have a short, stocky body covered in a unique pattern of white spots on a dark brown to black background. Their pectoral and dorsal fins are adorned with fine markings, adding to their visual appeal. They have a downturned mouth with barbels used for searching food along the substrate. Adults typically reach about two and a half inches in length, making them suitable for small to medium aquariums.

Tank Size and Setup

A minimum tank size of 20 gallons is recommended for a small group of Sterbai Corys. They are social fish that do best in groups of at least six, which encourages natural schooling behavior. A soft sandy substrate is ideal to prevent damage to their sensitive barbels. Adding smooth rocks, driftwood, and live plants creates hiding spots and mimics their natural environment.

Water Parameters

Sterbai Corys are adaptable but thrive in stable water conditions. Ideal temperature ranges from 73 to 79 degrees Fahrenheit. They prefer slightly acidic to neutral water with soft to moderate hardness. Regular water changes and clean filtration are essential to keep these bottom dwellers healthy and active.

Diet and Feeding

Sterbai Corys are omnivorous bottom feeders. They consume sinking pellets, wafers, and flakes as staples. Their diet can be supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia. Feeding once or twice daily in small amounts ensures all members of the school receive adequate nutrition.

Temperament and Behavior

Sterbai Corys are peaceful, social, and non-aggressive. They spend most of their time scavenging along the bottom for food and interacting with other Corydoras in the group. Their calm nature makes them excellent tank mates for small, peaceful fish, and they add lively activity to the lower levels of the aquarium.

Tank Mates

Ideal companions include small tetras, rasboras, guppies, dwarf gouramis, and other peaceful community fish. Avoid aggressive or large predatory species that may harass or harm them. Keeping them in schools enhances their confidence and overall behavior.

Breeding Information

Breeding Sterbai Corys is possible in well-maintained aquariums. They are egg layers and prefer to deposit eggs on broad leaves, glass, or smooth surfaces. Adults may guard the eggs but it is often recommended to remove the parents to prevent accidental eating of the eggs. Fry are small and require fine foods such as powdered fry food or infusoria.

Conclusion

The Sterbai Cory is an excellent choice for aquarists looking for a peaceful, visually striking, and active bottom-dwelling fish. Its unique spotted pattern, gentle temperament, and schooling behavior make it ideal for community and planted aquariums. With proper care, stable water, and suitable tank mates, Sterbai Corys thrive and bring life and interest to the lower levels of any freshwater tank.
