They are also known simply as the Blue Leg Hermit Crab, this member of the Diogenidae family is a colorful and reef-safe addition. Named after its bright and colorful red-banded blue legs, the Blue Leg Hermit Crab has claws of equal size and makes its home in abandoned snail shells. Take note that when the Blue Leg Hermit Crab is looking for a new home or if food supplies are insufficient, this minute scavenger may attack snails to obtain the shell for its home or eat the snails for food. To help prevent them from eating your snails and other crabs for the shells you can add Hermit Homes to provide empty shells for the crabs as they grow.
Supplement the diet of the Dwarf Blue Leg Hermit Crab with dried seaweed if insufficient algae are present. Though an efficient scavenger, and due to its small size, the Blue Leg Hermit Crabs should be kept in groups for larger aquarium systems.
