She has not been an active crab from the start.

She isn't at all happy with her baths, but she tolerates them.
It seems as though she wants to molt again, even though she had just come up from molting for Tammy in early December. She is a larger-sized medium. Isn't it too soon for her to molt again so soon? She is digging, and hanging out at the water bowls....and she seems lethargic when in the tank. (She becomes quite strong & active during the baths!)
Also, since she is showing premolt symptoms, should I move her back to the main tank now that her therapy is complete, so that she can molt there? I really don't wnat her molting in the ISO tank. I really rather all of my crabs molt in the main tanks. Plus, the substrate in the ISO isn't deep enough for her. (I didn't want her digging down while she was being treated.)
