- The Midbrain: This part handles vision, which is a betta’s primary sense for hunting and interacting with the world. It’s why they can spot you from across the room!

So, when your betta “dances” for its food or explores a new plant, it’s not just random movement. It’s the result of this tiny but powerful command center processing information and making decisions. They are far more than just a pretty face.
