The Blue Leg Reef Hermit Crab, Paguristes sp., features characteristic blue legs poking out of their shell. They are excellent scavengers and tank-cleaners that can help control algae and detritus and aerate sandy substrate. They are best housed in tanks with plenty of live rock and a sandy substrate.
