Common name: tricolor hermit

General information

The Blue-legged Hermit Crab, Clibanarius tricolor, is a small and colorful crustacean commonly found in the marine aquarium trade. Its vibrant blue legs, accented with red banding, make it a visually appealing addition to any reef tank. This species is known for its scavenging habits, helping to keep the aquarium clean by consuming detritus, leftover food, and algae.

Care

Clibanarius tricolor is hardy and adaptable, making it suitable for both novice and experienced aquarists. They thrive in tanks with plenty of live rock and a sandy substrate, which they use for shelter and foraging. It's important to provide a variety of shell sizes for these hermit crabs to move into as they grow. They are peaceful and can be kept with a wide range of tank mates.

Reproduction

In the home aquarium, breeding Clibanarius tricolor is quite rare. In the wild, after a courtship dance, the female carries fertilized eggs on her abdomen until they hatch into free-swimming larvae. These larvae go through several planktonic stages before settling to the bottom and adopting a shell.

Symbiosis

While not involved in the classic symbiotic relationships seen with some marine species, hermit crabs do play an important role in the cleanup crew of a reef tank, indirectly benefiting other inhabitants by maintaining water quality and reducing detritus.

Habitat

The Blue-legged Hermit Crab is native to the Caribbean Sea and can be found in shallow waters, often hiding among the rocks and coral rubble. They are accustomed to a tropical climate and require similar water conditions in captivity.
