Red claw crabs, also known as red-clawed crabs, are omnivores and eat both animal-based and plant-based material. Shrimp pellets and other sinking foods are ideal for feeding pet red claw crabs.
Red claw crabs, Perisesarma bidens, are opportunistic feeders and eat nearly anything they can reach with their claws, which means that a species-only tank is best since they could eat their tank mates. In addition to sinking pellets as a staple food, red claw crabs do well on fish flakes, brine shrimp, bloodworms and lightly cooked vegetables, which can be rotated weekly to keep their diet novel and interesting. Crab food can be purchased at most pet stores.
