The Blue Knuckle Hermit Crab has neon blue legs that make them a fan favorite. They will scavenge fish waste, algae, cyanobacteria, and detritus that have been deposited on live rock and substrate. Not only do they eat the aquarium's waste but they will also turn the sand, which aerates it. These little guys can find their way into even the smallest of spaces. Like all hermit crabs, they make their home in empty snail shells, be sure to have an array of empty shells available for them to move into when they grow. They will also take housing matters into their own pincers by occasionally eating a snail and taking that shell over; smaller snails are especially at risk. The Blue Knuckle hermit crabs are very hardy but are sensitive to copper.
