Origin and Distribution

Sterbai Corydoras are native to slow-moving rivers, streams, and floodplains in the Amazon Basin. These environments are characterized by soft, sandy substrates and abundant leaf litter, where these fish forage for food.

Colors and Markings

Sterbai Corydoras are striking with their dark bodies covered in white or light-yellow spots. Their fins often exhibit orange or yellow hues, particularly the pectoral fins. This unique pattern makes them one of the most visually appealing corydoras species.

Tankmates

These peaceful bottom-dwellers are excellent community tank members. Ideal tankmates include:

• Small, non-aggressive fish such as tetras, rasboras, or guppies
• Other bottom-dwellers like plecos or loaches
• Shrimp and snails

Avoid housing them with large, aggressive species that may outcompete them for food or disturb their peaceful nature.

Habitat and Care

Sterbai Corydoras thrive in aquariums designed to mimic their natural habitat. Consider the following:

• Tank Setup: Use a soft, sandy substrate to protect their delicate barbels. Add driftwood, rocks, and live plants to create hiding spots and shaded areas.
• Water Quality: Maintain good water quality with a gentle current and stable parameters. Use a high-quality filtration system that won’t disturb the substrate.
• Maintenance: Perform regular water changes to ensure low levels of nitrates and other harmful substances.

Diet and Feeding

Sterbai Corydoras are omnivorous and enjoy a varied diet. Their food preferences include:

• Sinking pellets or wafers designed for bottom-feeders
• Live or frozen foods like bloodworms, brine shrimp, or daphnia
• Blanched vegetables such as zucchini or cucumber

Feed them small amounts 1-2 times daily, ensuring food reaches the bottom of the tank.

Gender Differences

Mature females are generally larger and rounder than males, particularly when viewed from above. Males are slimmer and often more active.

Breeding

Breeding Sterbai Corydoras is achievable in a home aquarium with the right setup:

1. Breeding Tank: Use a separate tank with a sandy substrate and slightly cooler water.
2. Conditioning: Feed adults a high-protein diet to prepare them for spawning.
3. Spawning: Females lay eggs on flat surfaces like leaves or glass, which males fertilize.
4. Care for Eggs: Remove adults after spawning to protect the eggs. Fry hatch within 4-6 days and can be fed infusoria or powdered fry food.
