Care
Sally Lightfoot Crabs are relatively easy to care for, provided they have ample space to roam and a variety of surfaces to climb on. They are excellent scavengers, feeding on algae, detritus, and leftover food, which helps keep the tank clean. However, they may also prey on small, slow-moving fish or invertebrates, so tank mates should be chosen with care.
Reproduction
In the wild, Percnon gibbesi breeds seasonally, with females carrying eggs beneath their abdomens until they hatch. In captivity, breeding is less common, but with optimal conditions, it is possible to observe larval stages in the aquarium.
Habitat
Native to the tropical Western Atlantic and the Caribbean, Sally Lightfoot Crabs are found in a range of habitats from rocky shores to coral reefs. They are well-adapted to intertidal zones and can often be seen basking in shallow waters.
