Sterbai corydoras are distinctive bottom-dwellers with a bold spotted pattern and bright orange pectoral fins. Unlike many corydoras they tolerate warmer water, making them suitable tankmates for discus and other warm-water species.

Care Guide

Diet

Sterbai corydoras are omnivores that thrive on sinking pellets and algae wafers as staple foods. Supplement 2-3 times weekly with frozen bloodworms, daphnia, or brine shrimp to encourage natural foraging behavior. Feed small amounts that are consumed within 2-3 minutes; they will scavenge the substrate for missed food.

Behavior

These peaceful bottom-dwellers are highly social and should always be kept in groups of 6 or more to exhibit natural schooling behavior and reduce stress. They spend most of their time sifting through substrate in search of food, aerating the tank bottom and helping maintain water quality. They are nocturnal and most active during dawn and dusk, though they may emerge during the day in well-established tanks.

Breeding

Breeding sterbai corydoras in captivity is possible but requires patience and specific conditions including cooler water temperatures (22-24°C), frequent water changes, and high-quality live or frozen foods. Males will chase females in a characteristic T-position to fertilize eggs, which are typically laid on tank glass or plants. Fry are small and require infusoria or liquid fry food initially before graduating to micro pellets.

Tank Mates

Common Diseases

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots on body and fins, rapid breathing, lethargy, rubbing against objects

Treatment

Raise temperature gradually to 28-30°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich treatment; treat for 7-10 days

Fin Rot

Symptoms

Frayed or deteriorating fins, discoloration at fin edges, lethargy

Treatment

Perform 50% water change immediately, improve water quality with frequent changes, use antibacterial medication if severe; ensure good filtration and avoid sharp decorations

Barbel Loss/Erosion

Symptoms

Shortened or missing barbels, difficulty locating food

Treatment

Often caused by poor water quality or substrate abrasion; improve water conditions with frequent changes, use fine sand substrate, and ensure adequate nutrition with quality foods

Columnaris (Flexibacter columnaris)

Symptoms

Cottony white growth on mouth or body, loss of appetite, rapid breathing

Treatment

Perform 50% water change, raise temperature to 28°C, use antibacterial medication; improve water quality and remove any sharp objects that may cause injury
