I bought a 3 hermit crabs back in 2006 the very first one I bought lived and the other 2 died in the molting process a week after I bought them. Since then I've only had him. I know that hermit crabs are happy with other crabs and that they are social creatures. As you can see it's 2012 and he is still alone. I've thought about buying him another crab but I don't trust pet stores that much. I don't wanna buy a sick crab that will get my crab sick and soon end up with 2 dead crabs. I say this because it has happened to me but wit a different species of crabs. Should I keep him alone like he has been for all these years? I mean I want what's good for him but I am also protective of him. I don't want no sick crab from some store. What do ya'll think? Thanks.
