How many Bronze Corydoras should I keep together?
Corydoras are social fish and should be kept in groups of at least six. Keeping them in schools encourages natural behavior and reduces stress. Groups also make them more active and visible, as they interact with each other frequently. A larger group helps them feel safe and confident, especially when exploring the aquarium bottom for food. They rely on the presence of companions for comfort, and a single Corydoras can become shy and less active. Ensuring the tank is spacious enough for their group is important to prevent overcrowding.

What should I feed Bronze Corydoras?
Bronze Corydoras are omnivores and enjoy a varied diet. High-quality sinking pellets or wafers are ideal. Supplementing with live or frozen foods like bloodworms, brine shrimp, or daphnia provides protein. Blanched vegetables such as zucchini or spinach offer necessary nutrients. They forage constantly, so multiple small feedings a day work better than one large feeding. Avoid feeding foods that float at the surface, as Corydoras prefer bottom feeding. Ensuring a balanced diet supports growth, vibrant color, and overall health.

Do Bronze Corydoras need plants in the aquarium?
Plants are beneficial but not required for survival. They provide hiding spots, reduce stress, and create a natural environment. Live plants help maintain water quality by absorbing excess nutrients and offering shade. Smooth-leaved plants like Java fern or Anubias are ideal, as they do not damage the Corydoras’ sensitive barbels. Driftwood, rocks, and caves also serve as hiding spaces. A combination of substrate, plants, and décor ensures a comfortable environment, mimicking their natural habitat while promoting activity and well-being.

How often should I clean the tank with Bronze Corydoras?
Regular cleaning is essential to maintain water quality. Weekly water changes of 25-30% prevent the buildup of harmful chemicals like ammonia and nitrites.
