Corydoras fish swim to the surface primarily to gulp air, as they possess a specialized swim bladder that allows them to extract oxygen from the air. This behavior is particularly common in low-oxygen environments where dissolved oxygen levels in the water are insufficient for their needs. Additionally, they may surface to explore their surroundings or find food.
