OK,,,, I do have crabs there in my tank.... now with the question. I used to have a fish only tank with live rock and crushed coral in it, I am beginning to switch over the coral to "live" sand and make this tank hopefully look nice. My two kids along with my wife made a trip to the store and purchased 2 large "hermit crabs" (I think) and decided they wanted them in the tank. This was about 3 weeks ago. Man they looked great in there and everything was going great till Thursday evening. The largest one named "Snuggles" moved to a area in a piece of live rock and started to go thru a transformation. He began to shed is pinchers and face. And then presto next day there he is walking around again. I will try to include a couple pictures. What I want to know is...IS THIS NORMAL? and second of all Am I the only Dumb one that names every animal that goes into the tank?
This top picture is where he did his work
This picture was after the transformation...
