Black Leg Hermit

Florida Black Leg Hermit Crabs are very active and well known for controlling various types of algae including hair algae and are considered to be reef safe with caution. They can be aggressive to snails for a new shell. Be sure to have empty shells for them to avoid this.  Black Legs in the wild feed upon many types of algae and do a wonderful job within a reef tank consuming algae as well as leftovers.
