Genus
Common name: Hermit Crabs
Scientific name: Pagurus
Pagurus is a genus of hermit crabs that are popular in the reefkeeping hobby for their role in cleaning and maintaining the aquarium ecosystem. These crustaceans are known for inhabiting empty snail shells to protect their soft abdomens, frequently changing shells as they grow. They are scavengers, feeding on detritus and uneaten food, and are generally peaceful, making them suitable for most community tanks. Their behavior and shell-swapping antics can add an interesting dynamic to the aquarium.
