General: The Red Legged Hermit Crab (Paguristes cadenati) can play a pivotal role in helping to maintain a saltwater aquarium. The Red Legged Hermit Crab will help to clean algae from rock, as well as the substrate. However, it is important to closely monitor the number of Red Legged Crabs in the aquarium, as they can easily become overwhelming towards other invertebrates. As a strong competitor, the Red Legged Hermit will efficiently clear an aquarium of food. If there are too many of the Red Legged Hermit, it is likely that they will outcompete snails, as well as various species of coral. A useful tool in this hobby, this Hermit should be used with caution.

Aquarium Diet (Omnivore): Brine Shrimp, Baby Brine Shrimp, Mysis Shrimp, Krill, Clam, Spirulina, and Daphnia
