Moulting Results

[crabbypattay]

Ok so I have a hermit crab that has been under the sand for a little over 3 months and now today he came out which really makes me happy! When I first got him his exoskeleton was a really dark red but now it's a lighter red with some very apparent blue spots. Does this mean he's lacking calcium or is he alright?
