Arrow Crab

Spindly legs and a pointy head make this crab look more like a spider. Its long legs give it a good vantage point to search for its preferred prey- bristle worms. It may decimate populations of these useful scavengers in small aquariums, so is normally best kept in large tanks. It will also eagerly feed on fish food. Because of its large size and strength it may prey on other crustaceans, even those of similar size such as Coral Banded shrimp. It can grow up to a 6 inches leg span.
