Common name: Hermit Crabs

Diogenidae, commonly known as hermit crabs, are a family of decapod crustaceans. They are known for their behavior of occupying empty snail shells to protect their soft abdomens. Hermit crabs are popular in reef aquariums for their role in cleaning up detritus and uneaten food. They come in various sizes and colors, with species like the Scarlet Reef Hermit (Paguristes cadenati) being particularly favored for their algae-eating habits. It's important to provide a variety of shell sizes for them to upgrade to as they grow.
