Hi I'm sarbrand and I have 11 crabs. 9 pps and 2Es. All my crabs have molted except Big E. He refuses to go into a hidey or dig in the sand. He just sits and looks around all day or climb the top of the screen. His shell is to small and he looks like he's ready to burst. I've tried every type of shell but he just won't change. Any ideas about this Crazy lovable E?
