Description:
The Blue Leg Hermit Crab is a small, active, and colorful scavenger commonly found in reef aquariums. Known for its striking blue legs and red body, this hermit crab is an excellent addition to clean-up crews, as it helps maintain tank hygiene by eating algae, detritus, and uneaten food. Its hardy nature and peaceful temperament make it a popular choice for both beginner and experienced marine aquarists.
Care Level:

Temperament:
- Behavior: Peaceful, active, and social.
-
Compatibility:
- Ideal for community tanks, as it does well with a wide range of peaceful marine fish, invertebrates, and corals.
- Can sometimes compete with other hermit crabs or snails for shells, so it's important to provide a variety of shells in the tank.
- It may occasionally flip over if it finds itself in a tough spot but will right itself without issue.
Size:
- Adult Size: 1–1.5 inches (2.5–3.8 cm).
- Growth: Small and compact, perfect for aquariums of various sizes.
Reef Compatibility:
- Reef-safe and ideal for reef tanks, as it does not damage corals or other invertebrates.
- It helps control algae growth on live rock and glass, but care should be taken to ensure it does not disturb delicate coral species while foraging.
Additional Notes:
Blue Leg Hermit Crabs are opportunistic feeders, mainly eating algae, detritus, and leftover food, which helps maintain a clean environment in the tank. While they can occasionally be seen "climbing" on corals or rocks, they will not harm them. Provide a variety of empty shells to allow for proper molting and shell replacement. These crabs are excellent for adding diversity to the clean-up crew and are fun to watch as they scurry around the tank. With proper care, they can live for several years in a well-maintained reef aquarium.
