Tiny Blue Legged Hermit Crabs

Hermit Crabs are an important part of the clean-up crew in any reef tank.

Blue-legged hermit crabs are rather small to get into all the little spots in a reef tank to find food, and will need new shells as they grow, sometimes stealing shells from snails and each other if they aren't available.

They will eat a variety of algae and detritus on the rocks and sand.

For most reef tanks it's recommended to have 1 per gallon, and to replenish them every couple years.

Reef tanks only, predator fish like triggers, puffers, groupers, etc will eat most inverts.
