Orange claw hermit crab, Calcinus tibicen, are common but not as common as blue leg hermits. They are shallow water hermits found throughout Florida and the Caribbean. Like many of the small hermits they are often used as part of a clean up crew because they will eat any stray bits of food, and will graze on unwanted algae. They are small crabs and rarely get big enough to live in much more than a medium sized astrea or cerith snail shell but most of the time, orange claw hermit crabs are bigger than blue legs.
They are compatible with most other crabs, and don’t eat live corals or gorgonia. Orange claw hermit crabs are sometimes also called red legs but our common name is more accurate.
