Here's why:
* Diet: Grass carp primarily feed on aquatic plants, grasses, and algae.
* Lack of predatory adaptations: They lack the sharp teeth, claws, or other physical adaptations needed to hunt and kill other animals.
While they may occasionally consume small insects or crustaceans, their primary food source is plant matter.
Therefore, grass carp are considered prey to larger fish like bass, pike, and catfish, and are not predators themselves.
