The Arrow Crab, also known as the Spider Crab, has extremely long legs. It is called the Arrow Crab because of the shape of the body and head. The size is variable, many reaching six inches, and some up to 10 inches. The Arrow Crab is hardy, long lived invertebrate that can be housed in the reef tank. It is known to attack crustaceans such as Banded Coral Shrimp, and slow moving fish, therefore this crab should be combined with selected species only.
