Blue Leg Hermits are the undisputed king of algae removal in an aquarium. While they will eat meaty foods, they are great at controlling hair and other macroalgaes. They are small hermits, so they are excellent at getting into corners and hard to reach areas that other animals cannot reach. As with all hermits, they will scuffle among themselves, and exchange shells as they get larger. Available individually, as well as 10, 25, 50 and 100 packs.
