Natural habitat

Bronze Corydoras thrive in the soft substrates of South American rivers, particularly in calm waters with fine sand or gravel where they forage for food. They are found among the dense vegetation typical of the Rio de la Plata Basin, creating a natural cover and breeding ground.

Where they are found

Their range spans from Venezuela to southern Brazil, though the exact distribution of 'true' Corydoras aeneus is complex due to the existence of multiple species closely resembling each other.

Aquarium care

To keep Bronze Corydoras healthy, it's essential to replicate their natural habitat with soft substrate and plenty of hiding spots. A well-cycled tank with gentle filtration that maintains stable water parameters is crucial. Regular water changes will help keep water quality high and ensure the wellbeing of these fish.

Feeding

Feed Corydoras aeneus a balanced diet including sinking pellets, live or frozen food like bloodworms and brine shrimp, and plenty of plant matter to keep them healthy. Varied diets help prevent malnutrition.

Compatibility

These fish are highly social and should be kept in groups of 6 or more. They are compatible with many peaceful community fish and are generally considered shrimp-safe, though they may occasionally eat very small shrimp.

Breeding

Breeding Bronze Corydoras requires conditioning with a mix of nutritious foods. Spawning is typically triggered by a water change with cooler water. During courtship, males chase and prepare nesting sites, leading to the fertilization and laying of sticky eggs by females. Adults should be removed post-spawning to protect the eggs.
