The Ultimate Cleaner-Blue Knuckle Hermit

The Blue Knuckle Hermit Crab is an ideal addition into any saltwater aquarium. They will scavenge fish waste, algae, cyanobacteria and detritus that has deposited on the live rock and substrate. Not only do they eat the aquarium’s waste but they will also aerate the sand by turning it. These little guys can find their way into even the smallest of spaces. They will take housing matters into their own pincers if empty shells are not available by occasionally eating a snail and taking the shell.
