Electric Blue Hermit Crab

Hermit crabs need to live inside of a snail shell in order to keep their soft bodies safe. Even with many shells available hermit crabs will occasionally kill snails in order to take their shell. Please ask our staff and we will be happy to supply you with some empty shells.

A very uncommon animal, it is also known as the Blue Knuckle crab, and should not to be confused for the Blue Leg crab which stays quite small. The Electric Blue crab is a medium sized hermit crab and consumes mainly algae including some hair algae and cyanobacteria. It is considered reef safe, however it is an opportunistic omnivore and will take food where it can find it. It will also eat detritus, fish food, and anything else edible.
