I have had been a hermit crab owner for the past 7 yrs. I have been to many internet sites and read books. As I see it, many new owners do not know much about hermit crabs when purchasing. These notes were compiled by my notes from personal experience, books I have read and internet resources from other hermit crab owners. In short, they are growing.
Many people see that their hermit crab is weak and think it is dead.
I look at it and make sure it's doing well. These molting were done while they buried themselves in the opening of much larger shells. Some of my buddies are fashion conscious and have changed shells many times. They then strut around the cage and show off when, normally, they would be resting. Hermit crabs should be no different.
