Is my arrow crab preggers??? :)

[littlefoxx]

So my boyfriend loves arrow crabs and put a male in with our current female a week ago. Today I noticed she has a sac like thing? I watched her kinda like open the bottom of it and put food in… didnt get a video I was too shocked! She then closed it. But her bottom is for sure more round and white than it was a few days ago. Is she pregnant?

So she keeps opening her little pouch and sticking food in (never seen her do that before) and is hanging out in one spot. Pretty sure shes got babies
