You’ve probably heard about fish schooling, but have you heard about fish shoaling? 🐟 Schooling and shoaling are both collective behaviors of fish, but they differ in how the fish move together! If a group of fish is swimming in the same direction in a coordinated manner, they are schooling. However, if a group of fish is swimming together for social reasons but without any coordinated movement, they are shoaling! | OdySea Aquarium
