Was he every any other color? I've seen 3-inch C. armatum that were more like the ones Kashta posted, so I suppose that threw me off.
It's a big difference in color. Around 50 seconds into her video, Jacki mentions that he changed color.. just before commenting how dexterous he is.
I can see she has the same crab I do... just my Crusty has the large claw on the other side. Mine went through the same color change.
