What's my hermit crab doing to the little one?

[scu ba]

Yesturday the large blue leg hermit started to try to get the smaller hermit out of his/her shell. Is it trying to kill it or is it mating season? Thanks

its just being agressive, it might want its shell or is just hungry ***)

I have read that they are "doing it" when they try to get each other out of their shells.

Mine kill each other doing that i guess they take each others shells.

Well if the larger is tring to get the smaller then its not for the shell either btheir doing it or the larger one i hungry. Just logical
