Questionhi when i got my hermit crabs a couple of months ago i didnt notice the crab had a leg missing and bought it know its growing it back so is there anything i need to know about that stuff?
AnswerNot a lot, he will do it when he molts. He may develop a little tiny nubby leg where that one is missing called a "gel leg" sometime before he molts.
Generally the new leg will be a little smaller the first time but be normal sized by the second molt.
