Hi I got my crabs a few weeks ago and the other day I found this website an decided to join I have two crabs herman and hermynie and the they are both dug under. In the beginning they were always active at night and in the day hid in the coconut hut. Now they are both under and yesterday hermynie was in the hut and I went to look at her and she freaked out and started pinching me, same with herman two days before. they are usually very nice and never pinch and walk all over my hand and room. So now they are buried again and I don't here from them accept for the occasionally scratching underground in the night. Could they be molting? please help. Kinda new to all this.
