I disagree with the fact that hermits don't kill live fish, but the kind I have and are talking about is the wrong one, the big 1.5" kind. Maybe I just the extreme, but a fish will simply swim by, no matter what size, and the hermit will reach out to try and snatch it. Maybe the regal was sick or something, but she was eating and swimming fine 2 hrs. before we caught the crab eating her. I need to get some of those smaller ones when I take these 2 guys back.
