Natural History: The Arrow Crab is a nocturnal resident of coral reefs, hiding by day beneath rocks and in crevices. At night it emerges to scavenge or prey on bristle worms, feather duster worms, or other crustacean species.
Husbandry: The Arrow Crab may attack other crustaceans, such as shrimp. It may feed on bristle worms and eliminate them from an aquarium. Refuges should be provided for them. They will scavenge excess food. This species is very territorial and it should be housed singly.
