Native Habitat and Species Information

Dwarf Blue Leg Hermit Crab native habitat, distribution, behavior & aquarium compatibility.

The Dwarf Blue Leg Hermit Crab or as it is more commonly known the Blue Leg Hermit Crab is a very small species (approx. 1 inch) that has blue legs with small red banding. The Blue Leg Hermit Crab is a "Equal-handed Hermit Crab" in that both of its claws are of equal size. Blue Leg Hermit Crabs make their homes out of abandoned snail shells or similar shells if available, when no empty shells are available they will often kill a snail and takeover its shell.

As a whole, this species is very peaceful and will go about its business of eating small morsels of leftover meaty foods or macro algae. This is an excellent "tank cleaner" and is commonly found in "reef janitors" or "cleaning crew" packs. Because of their small size, the Blue Leg Hermit Crab is able to forage in locations within the live rock and reef that other larger janitors cannot reach. This makes them an invaluable addition to a balanced cleaning crew along with the larger hermit crabs and snails.
