Changshou crab is a kind of freshwater crab that lives in rivers. Their diet is omnivorous, feeding on plants and small animals. Longevity crabs mainly feed on bottom plants and small animals, such as aquatic plants, algae, small benthos and insects. Their mouthparts are strong enough to crush and swallow small hard-shelled animals.

Longevity crabs can also eat some nutritious foods, such as tofu and eggs. These foods can provide high-quality protein, vitamins and other nutrients needed by Xiangshou crab, and enhance its vitality and immunity.
