Hi all. I've been watching events unfold in my tank regarding my group of hermits, whilst also focusing on introducing my corals, making several posts regarding their care, placement etc. Sadly, I've come to the conclusion that my group of six has sadly diminished to one. Now, a couple of months ago I removed a large one that had become a little too aggressive for my liking, the guy in the shop I took it to said "wow, what a beauty, that's going straight in my display tank". All parties happy then. Last week I noticed, for the first time in my experience, one of them out of it's shell nestling into a crevice. I contemplated moving it amongst shells, I have loads in the tank, but decided not to in case I damaged it. Anyway, next morning it was gone. What I'm wondering is it a common place to loose hermits when they seem to be doing well? Also, should I restock with the remaining one in, or incase that's the cause of the problem, remove it and start afresh? Any thoughts would be great, thanks.
