Bronze Corydoras

Environment

Plan for at least 80 liters and a group of at least 6 individuals, as it is a gregarious fish that deteriorates when isolated. Use fine sand or rounded gravel substrate to protect its barbels, water between 22 and 26 °C, pH 6 to 7.5. Some driftwood and shaded areas reassure it.

Feeding

Bottom-dwelling omnivore, it consumes sinking pellets and tablets, as well as live or frozen prey (bloodworms, brine shrimp). Make sure it receives its share: food must reach the bottom and not be intercepted by surface fish.

Health & common diseases

Bronze corydoras are sensitive to barbel rot caused by sharp substrate or dirty bottom, as well as bacterial infections and fungus related to poor water quality. They can be affected by ich (ichthyophthirius), especially during stress or temperature fluctuations. Monitor the condition of barbels (redness, shrinkage), breathing difficulties, frayed fins, and any lethargic behavior. Prevent these problems by maintaining fine sand, clean water (regular changes), and a varied diet to strengthen their immune system.

Tips & tankmates

Avoid sharp and cutting substrates that injure and infect its barbels. Never keep it alone or in pairs. It sometimes rises to the surface to gulp a bubble of air, this is normal intestinal breathing behavior, not a sign of distress.
