Don't let the small size of the Dwarf Blue Leg Hermit Crab fool you. As a voracious scavenger, this omnivore can get into the smallest crevices and openings within live rock to consume nuisance algae including hair algae and cyanobacteria. While doing so, Clibanarius tricolor also helps aerate sand substrate, thereby encouraging growth and activity of beneficial bacteria.

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 Dwarf 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.

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 Dwarf Blue Leg Hermit Crabs should be kept in groups for larger aquarium systems.

Approximate Purchase Size: 1/4" to 3/4"

Customer Testimonials

These little hermit crabs are a must have in your reef tank. Dwarf Blue Leg Hermit Crabs are excellent scavengers and nuisance algae consumers. Plus, they are fun to watch. Be sure to purchase a group, as they are quite small, and don't forget to keep some extra shells for their new homes.

The Blue Leg Hermit Crab's small size is great for feeding on detritus in small places on your live rock. However, they will need to be replaced occasionally due to their carnivorous ways.
Sherry Kennedy Hillsdale , WY
I have three types of dwarf hermit crabs in my 110 gallon tank. The Blue Legs are fun to watch. They seem to change shells more often than my Jades and Scarlets. They will even wrestle each other (no harm done) in their efforts to see who has the best shell. I saw one crab pulled out of a shell another crab wanted, but he found a new one and was fine. Yesterday, I saw a Blue Leg pick out a shell much too large and he had trouble walking across the sand. A very funny crab indeed!
