Well I was sitting in my chair enjoying my 24g. One of the hermits got stuck on his back and was trying to turn over. No biggie happens all the time and they usually flip over. Except this time my cleaner shrimp saw it as an opportunity. I didn't realize at first what the shrimp was doing until it was too late... it was a blurred jumble of shirmp legs and hermit shell moving around... when it finally stopped the crab was dead and the shrimp was enjoying his snack so I took a pic. The other hermits came scrambling out of nowhere to come get any leftovers and of course fight for the empty shell.
