Some of you may remember a little over a month ago in February, when my hermit crab Tiffany had a suprise molt in her water bowl, and emerged almost a week later missing all of the limbs on the left side of her body.
I had to hand-feed her using a tooth pick, and keep constant check on her. She made what appeared to be a wonderful and quick recovery. She started to sproud the beginnings of little gel legs, and even got to the point where she could feed herself, and eventually she wouldn't let me feed her at all, she had become so independent. She was doing great, and I was thinking about adding in a few more hermit crabs for her to play with, when about four days ago she just stopped moving.
She stayed in the same spot for over a day, which I found odd, because she tends to be very active. The next day I squirted her lightly with water. No reaction. I tried to give her a bath, but gave up immediately because she just stayed in her shell. I put her back in her tank and waited for the too familiar fish smell.
It finally came this morning. She never even popped out of her shell or anything. She was still in it, and I could see her little head leaning against the inside wall. I picked her up and she kind of shifted a bit, but it was only out of deadness. I took her outside to burry her, and when I put her into her grave, she fell all the way out of her shell. It was the first time I ever saw her tummy, and it was all black and blue and gooey, which I know it is not supposed to be.
Her death took me by complete suprise, and I still don't know what happened.
Does anybody have any idea?
Is this related to her molt, or is it something completely different? And why did her abdomen look like she had frost bite??
