The Blue Leg Hermit Crab (Clibanarius tricolor) is a reef safe hermit crab which eats algae and left over food. The Blue Leg hermit Crab has become popular in the home aquarium earning its keep by consuming unwanted algae. They are an omnivorous bottom feeder which has been photographed eating red slime algae aka blue green algae aka cyanobacteria. Many aquarists have observed the Blue Leg Hermit Crab eating other various types of unwated algae like hair algae and detritus which feed the growth of nuisance algae of all types.

The Saltwater Blue Leg Hermit Crab also answers to the names blue-legged hermit crab, tricolor hermit crab, blueleg reef hermit crab, equal handed hermit crab and blueleg hermit crab. It is a nice addition to the aquarium as this crab stands out with it's bright blue legs. In addition the Blue Leg hermit Crab has lines of orange and black hence the scientific name Clibanarius tricolor. The Blue Leg hermit Crab is a native to the Caribbean and lives primarily in the tidal zones of rocky areas. These cabs live together by the thousands clinging to rocks as the tides move. In low tide they scavenge around to find food. Food to these crabs consists of anything edible ranging from detritus to algae and left over yummies.

Belonging to the Class Crustacea and Order Decapoda these hermits along with Porcelain Crabs belong to the Section Anomura, which consists of long antennae and four pairs of legs, for a total of 6 walking legs and 2 working legs which usually develop claws to be used in gathering food, for protection, and to move objects. The head of the Crab is connected to the thorax and covered by a shell called carapace. They have a smaller abdomen and tail compared to Shrimp and they keep this tucked beneath the carapace.

In order for Crabs to grow they need to shed their exoskeleton, a process called "molting", which allows them to remove their restricting shell and begin a new one. Often times in the home aquarium Crabs will leave this translucent shell in full view so it can serve as a distraction while the Crab finds a hiding place and allows its new shell to harden. Hermit Crabs use abandoned shells as their home. These Crabs usually have extended abdomens that they wrap around the inside of the spiraling shell leaving only their head and claws exposed. When approached these Crabs can recoil into the shell for protection. When a Hermit Crab grows it will often seek out a new larger shell.

I have ordered a bunch and they are all alive when they arrive and are all over the tank. A lot fun to watch. Everything form Reefs2Go has been perfect. I have ordered a lot from them. Customer Service is great also.

Hermit crabs!!!
Awesome crabs, arrived very small in early September and ar already huge. They do a great job cleaning my tank. A pleasure to watch.
Jared Johnson of WA
Great addition
Bought one on the BOGO deal, unfortunately one didn't survive the trip and R2G immediately credited my account. The one I still have does a wonderful job removing waste in my refugium and is so fun to watch. great for anyone that overfeeds.

Electric Blue Hermit Crabs
These are beautiful animals and are not at all shy. When small, they are good scavengers. Give them some dried algae or live macroalgae if your aquarium does not have much algae. They grow up to 2-inches across; however, Reef2Go sent me small ones, less than an inch long. I prefer them small, as I do not whether a two-inch specimen would be "reef safe."

Good cleaners, very fun to watch.

Little guys
These guys are really small so order more than you think you need. They all arrived healthy.

Great Buy!
We received our BOGO Blue Leg Hermit Crab and one of them is HUGE! The kids love to watch him attack the algae and he has already found a new shell (so he looks much bigger than before). We ordered some more and they are small, but we are looking forward to watching them grow! Thank you, Reefs2Go!

Great deal on blue leg h. crabs
I purchased the 100 blue leg hermit crab daily deal and was very happy to see they were ALL alive and active when I received them. R2G provided great acclimation directions and even provided the tubing for drip acclimation! I was very impressed with the transaction process, shipment and delivery. I will most definitely purchase from R2G again.

blue leg hermit crabs
A little on the small side but awsome at what they do, they work in pack on one rock at a time getting it done.
