Dardanus 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 snail shells, which they carry on their back as a portable home and protection. They are scavengers by nature, helping to control algae and detritus levels. Dardanus species often exhibit fascinating behaviors and can be quite interactive, making them a favorite among aquarists. They require a variety of shell sizes to accommodate their growth and should be provided with a diet that includes meaty and plant-based foods.
