Im assuming this is a common problem but my roommate awoke to not one but two hermit crabs walking around on the kitchen floor a good 5 feet away from the tank this morning, monkey see monkey do. He threw them both back in and they appear to be fine! Im assuming they are climbing from the rocks to the powerheads then up on the power cord. Anyone have any tips to prevent this from reoccurring other than a stern talking to which ive already done?
