I have had this anemone crab for over a year, so quite hardy I would say. Spends 90% of the time on the sand bed, will climb the rock but not often.
Note: not my photo taken online, if you really want me to i can take one of mine and post it. but mines looks just like this one...but my shell is a bit bigger and has to redish anemones on it and very active running around the sand bed.
