The snakehead is a fierce carnivorous fish. Like snakehead, it feeds on fish and shrimp. However, its predation mode is different from that of mandarin fish, and it never actively pursues prey. Snakehead often lurks in shallow water with turbid water and overgrown grass. If the water quality is clear and the water flow is slow or calm, it is mostly hidden under aquatic plants or in still water. When catching food, snakehead never pursues small fish with strong body and fast swimming ability, but pursues food with cunning means. When it found a small fish, it hid in the nearby aquatic plants and peeped quietly, waiting for the other party to relax its vigilance. When it swam near the snake head, it suddenly rushed forward and bit the small fish by surprise attack.
