Arrow Crab releasing its young

[fedor_phil]

I've just recently set up a new tank (6 gal, now fully cycled) and because of a small number of bristle worms, I added a Arrow Crab to help out, and after reading other posts, I intend to move it to another tank when its finished with the smaller tank. Tonight the Arrow is sitting on top of the live rock releasing its young into the tank.
Is there any reasonable possibility that any of the "young" will actually survive? I don't want an infestation of Arrow Crabs.

unless if you have 2 arrow crabs that mated then no;
no arrow crab infestation for you :thinking:

Could it have mated at the LFS? I know little on crabs.
