Blue Leg Hermit Crab – Clibanarius tricolor

\r\nBlue Leg Hermit Crabs are prized in reef aquariums for their scavenging and algae-eating abilities. Their small size allows them to devour algae from the smallest nooks. If algae becomes short in supply, these crabs are quick to feed on any extra meaty foods that may linger after feeding.

Most hermit crabs are scavengers. Some smaller hermit crabs will feed on algae like nuisance hair algae while larger hermit crabs are scavengers and carnivores. Most hermit crabs are opportunistic – they will not actively hunt for a fish or active invertebrates but will prey on sick, dead, or dying individuals. Only the larger hermits like those from the genuses Aniculus, Dardanus, Peguristes, and Petrochirus are a real threat to healthy, larger tankmates or to corals. Calcinus, Clibanarius, and Paguristes are some of the most common \
