Calcinus elegans has bright blue, orange, and white legs and claws, with black eyes on stalks. It reaches up to 4 cm in length (excluding shell). It carries a gastropod shell which it changes as it grows. It is an opportunistic omnivore feeding on algae, detritus, leftover food, and small invertebrates. It is very active and constantly explores the tank. It can be slightly aggressive towards other hermit crabs for shells. It is generally compatible with peaceful fish and corals.
