Hi guys, new to reefing and recently purchased some blue legged hermits online but when they came one was a dwarf zebra hermit. He has taken to our torch frag and literally doesn’t move off it, is this normal? Is he hurting it? Really appreciate some advice. We also had two reg legged hermits and one was murdered the other night despite loads of shells in the tank so one of the crabs is the culprit but as of yet we don’t know which one. Any advice on what hermits would do this for fun? About to introduce a green clown goby to tank and he’s only small and I’m worried he’ll be at risk. Do hermits attack the little clown gobys? Thanks.
