Tank size: Provide a tank with a minimum capacity of 20 gallons (75 liters) for a small group of Corydoras melanistius.

Water parameters: Maintain a temperature range of 72-80°F (22-27°C) and a pH level between 6.0 and 7.5. The water should be clean and well-filtered.

Tank setup: Include plants, caves, and driftwood for hiding spots. A sandy substrate is ideal to mimic their natural habitat.

Diet: Offer a varied diet including high-quality flake or pellet food, supplemented with small live or frozen foods like brine shrimp or bloodworms.

Tankmates: Keep them in a peaceful community tank with other small, non-aggressive species that won't outcompete them for food.

Maintenance: Perform regular water changes of around 25% every two weeks to maintain water quality.

Observation: Monitor their behavior and appearance regularly to detect any signs of illness or stress.
