Arrow crabs, sometimes called spider crabs, with their long legs and arrow-shaped bodies, are a great addition to larger, salt-water reef tanks. They are predators, but if properly fed they can co-exist with quick-moving fish and provide control for feather worm and bristle worm populations. They prefer a rocky substrate with hiding places and should not be kept with other crustaceans as they may prove aggressive.
