This is totally going to sound weird, but I bought two blue legged hermit crabs, yesterday, and today, I see a third one, without a shell? It looks like it’s molting, from what I’ve read online. This is my first time having these creatures, so I have no idea what’s going on. I attached two photos, Both shells are taken up with the crabs that I bought, but next to the second shell, there is a pair of blue legs and white meaty substance..... I put it next to the shell but it was originally found this morning under a rock....
Someone please explain how this is possible? I double checked, both shells are indeed taken up by the crabs, I can see their legs sticking out and they are moving. So where did this third one come from? and what do i do with it since it doesn't have a shell
