• Diet: Omnivore; it feeds on algae, detritus, small crustaceans, and organic waste it finds on rocks
• Care: Relatively easy to care for, but the nimble spray crab requires stable water parameters and sufficient food. It can be kept well in aquariums with other peaceful animals, but can be somewhat territorial
• Reproduction: Reproduction usually occurs through egg-laying, with eggs hatching in the water. The offspring develop through several larval stages
• Special Features: The Percnon gibbesi is particularly known for its ability to move quickly and agilely between rocks, which helps it find food and escape predators. It has striking, relatively large claws that it uses for both foraging and defense. This crab is very popular in reef aquariums as it cleans the substrate of algae and organic waste and has a decorative appearance.
