Metasesarma aubryi, commonly known as the Red Apple Crab, is a freshwater species that hails from the mangrove swamps of Southeast Asia. Characterized by its striking bright red carapace and chunky claws, this semi-terrestrial land crab is a wonderful addition to any invertebrate enthusiasts collection. These crabs are semi-aquatic and so must have both land and water paludarium, as they like to alternate between swimming and basking out of water. Their relatively small size, growing to about 2-3 inches in width, makes them suitable for various tank setups. However, it’s vital to ensure the tank is well-sealed, as these little climbers are known to attempt escapes. Red Apple Crabs are omnivores. They enjoy a mix of blanched vegetables, fish food, and protein sources like brine shrimp or bloodworms. The Red Apple Crab makes a delightful pet for those looking to keep something a little unusual and quirky. These crabs are known to be a little aggressive and pinchy, handle at your own risk.
