Arrow crab help?

[shrub125]

I just purchased an arrow crab last night, and because i didnt have a lot of time on my hands, i was only able to drip aclimate it for 1 and a half hours. Once the arrow crab was in the tank, it just sat down on my LR and didnt move for the entire night... Its just sitting there, may it be molting?

Well, it may be laying eggs if it is a female, or it could have a rare case of schalactitus (common in inverts)
