I got 3 purple pincher hermit crabs this week and I thought I would share some pics. I am still looking for some plant that won't take over and will stay small. The white shelled one is being shy so no close up pics. of him.
Not to doubt you know what your doing, but I thought hermit crabs needed lots of moisture, (beach like). I also thought they needed allot of area to roam (not that you haven't done that, and cannot they be territorial?
