Description
Clibanarius rutilus – Red Stripe Hermit Crab
Overview
Clibanarius rutilus, commonly called the Red Stripe Hermit Crab, is a hardy and attractive marine invertebrate prized in reef aquariums for its algae-eating habits and bright coloration. With its orange-red legs and distinctive banded shell, this hermit is both functional and ornamental.
Distribution
Native to the Western Atlantic, they are found from the Caribbean down to Brazil, typically in shallow coastal waters.
Habitat
These hermits thrive in seagrass beds, sandy lagoons, and rocky reef zones. In aquariums, they do best when provided with a mix of live rock, open sand, and a selection of empty shells to grow into.
