blue legged hermit crabs

[kien]

Generally speaking blue hermits are safe and good reef custodians. However, they are classified as scavengers, which means if the going gets tough, they will, well, scavenge and won't hesitate to eat whatever they can eat. I myself have never had any issues with my blue legged and I have quite a few starfish in my tank. Another concern is that if they start to get too cramped in their shells they will want to upgrade their crib..
