I rescued 2 hermit crabs from a souvenir shop about a month ago. When I got them home I noticed one was missing a leg--probably due to the awful conditions in the shop. With a little TLC, both the crabs are doing fine now, healthy and active. Yesterday, I noticed that the one missing the leg now has a little nubby spot where the leg used to be. It looks like a little bump covered with gel. I have heard that crabs grow new legs when they molt, and wondered if this is what is happening. If so, how long before the molt?
