The Blue Leg Hermit Crab, Clibanarius tricolor, is a species of hermit crab that is often sought by aquarium enthusiasts due to its ability to clean and maintain a healthy tank environment. These crabs are particularly efficient at removing hair algae and detritus from aquariums, and are also effective at removing some types of cyanobacteria and film algae. They can be found on the rocks and substrate of the aquarium during the day and night. They may become nocturnal if you keep predator fish.
The Blue Leg Hermit Crab can grow up to about one and a half inches in diameter. They are sociable creatures that do well in groups. While they are generally considered reef safe, they have been known to attack snails or other hermits for their shells. Providing extra empty shells can help to mitigate this behavior. Many aquarium enthusiasts enjoy their comical antics and find them to be an entertaining addition to their aquarium cleanup crew.
