Scientific Name: Percnon gibbesi. Sally Lightfoot Crabs, Percnon gibbesi, are collected from Atlantic waters bordering the Americas. These crabs are excellent cleaners within the reef aquarium, concentrating on a diet of both micro algae and uneaten foods. They are also one of the few animals that will eat bubble algae. Sally Lightfoot crabs have been known to associate with some species of urchins (Diadema sp.). The crab will scurry underneath the urchin in search of protection from possible predators.
