The Reason Fish Live in Japan’s Drainage Canals #animals #wildlife #facts

Description: In several cities across Japan, drainage canals are so clean that fish like koi and carp can actually live in them. But these fish aren’t just there for beauty, they also serve an important purpose. Koi and carp help keep the waterways clean by feeding on natural materials in the water, including algae, tiny aquatic plants, insect larvae, and other organic particles. In a way, they act like natural cleaners that help maintain the ecosystem. There’s also a surprising social effect. When people see fish swimming in the canals, they are far less likely to throw trash into the water. The presence of living fish encourages residents to care more about keeping the waterways clean.
