Arrow Crab.
A spindly, spider-like reef crab with a pointed nose and long legs — an oddball scavenger that hunts bristleworms and leftovers. Reef-safe with caution (it may bother small inverts or corals); give it rockwork and a 30-gallon-plus tank.
Live fish are priced per supplier batch — prices may vary. Call to confirm current pricing.

Good tank mates
A spider-like reef scavenger that is reef-safe with caution and best kept with fast, alert tankmates rather than anything small and slow. It will catch and eat small ornamental shrimp, tiny fish, and sometimes pick at sessile inverts, so avoid housing it with pricey cleaner shrimp, tiny gobies, or anything it can corner. One arrow crab per tank is wise, since they can be aggressive toward each other, and it generally coexists with larger active fish that can stay out of its reach.
Good to know
The arrow crab's body is shaped like a tiny dart with extremely long, jointed legs that can span many times the width of its compact triangular shell, giving it a daddy-longlegs look underwater.
