Hard to say but it may also be a small snail on the shell of the hermit.

Yes, you should provide a few larger empty shells for your hermits to move into when they outgrow their present shells.

 

i'll try to take a better pic i can see little black thing's moveing out of the sell now and then hope she's come's out i can't see her now

 

i don't think hermit crabs can breed in captivity.. i think they just release their eggs and sperm up into the water, and basically, whatever happens, happens... and in an aquarium, the "babies" would get sucked up into the skimmer, filters, or whatever... i don't know 100% though... maybe someone could do a search on "breeding of hermit crabs in the home aquarium" or something... oh, and as far as the shell goes, they don't grow their own.. they either find an empty one or kill whatever's inside it and then take it...
