I just joined, but have been using the site for months now for hermitcrab newbie faqs and info - I just wanna say thanks for all the help and you guys don't even know it

I got my hermits on a trip to lake george with my boss and her kid... . I know what you're thinking hold up- lmaooo first off I went to school for veterinary medicine and love animals of all shapes of sizes! I have a western hognose and have been wanting to use her alternate tanks and get a lizard or another snake for some time now... . when I saw the hermies, I thought, you already the have the tank, cf, extra decor, dishes etc, why not hermies!! I bought 2, turbo and dorito, since I know they don't like to be alone. In the months since I got them, my duo has became a trio with the addition of Pluto.
(and my fate has been sealed and I shall end up a little old lady with my cats and hermit crabs) :X but that's besides the point.
so today I took my dog to petco.
the small hermys were 5bucks. *sigh*
I decided to take a look.
They were all PPs and I was looking at a few when I saw this light/lavender one. so my first 'stupid' question new to the boards is: did I buy a hermy who has just molted? about to molt? maybe just really young (it is tiiiny)? sick? or who is just on the lighter side?

also!
apon further inspection at home in iso, Ive noticed the cracked shell! i've never had a hermy with a cracked shell as I would never put one in to offer.. it looks to me like Pluto's abdomen can come out and i feel bad since i gave Pluto a SWbath and the shell a once over with a toothbrush to get petco crusties off it and im sure in hindsight Pluto was scared sh***ess, it cetainly explains to me why pluto has been extttrrremely shy, I think he/she feels extremely exposed and refuses to budge until all is calm.
but is this also cause for concern and could explain the light color?
well currently my newest and littlest, is in iso surrounded with new shell options, fresh food and water(s) and awaiting advice.
you guys are the best,
Amanda
