Short Answer: Because they swim in schools! 🐠🧠
Explanation: Fish are known to swim in schools, which means they swim together in large numbers. This can be interpreted as them being "smart" because they understand the power of teamwork and collaboration. Just like smart students who learn better when studying in groups, fish become intelligent by swimming in schools! 🏫🐟 It's a funny way to look at their behavior and appreciate their social skills!
