Betta fish, or Betta splendens, breathe air using their labyrinth organ, which acts like lungs. They primarily breathe through gills in water. However, when dissolved oxygen levels are low, they can gulp air at the water surface. Bettas are facultative air breathers, meaning they can choose to breathe air without needing to do it all the time.
When the betta fish surfaces, they gulp air into the labyrinth organ. This organ absorbs oxygen, allowing the fish to thrive in oxygen-poor environments. As a result, betta fish can survive in small bowls or tanks, unlike most fish that require extensive aquatic environments.
This ability to breathe air not only aids in their survival but also contributes to their unique behavior. Betta fish have a reputation for being territorial and can engage in agitated displays. Understanding their breathing mechanism provides insight into their habits and habitat needs. In the following section, we will explore how environmental factors influence betta fish health and behavior. We will discuss optimal tank conditions, dietary needs, and social interactions that support their well-being.
