The crab that has been buried for 3-4 weeks preparing to molt has been attacked! He wasn't all the way to the bottom of the tank, just about half way down. This morning, Taz, my aggressive PP, was sitting on top of Mr. Krabs. When I picked Taz up, one of Mr Krabs' legs came with Taz. Upon further examination, it was a hollow leg. Mr Krabs had molted and Taz had dug him up and was picking at him. Mr. Krabs was not moving and his BP was kinda limp looking. There is no smell yet. I immediately put him in ISO to protect him, with his exo. I put a hut over him and supplied fresh and salt water. What else should I do? I keep reading all these stories that people have had tons of uneventful molts, yet out of my 4, 3 have been traumatic! What am I doing wrong? I have 4 inches of sand for them to bury in. I don't know why he didn't go all the way down. Are molts harder on E's than PP's? Do they require any special care during the molt?
