What size of hermits? How small?
I'd buy from MR's vendors before paying $1.25 at an LFS for a small blue leg hermit.
Good cause Blue legged hermits are nasty...they will murder all of your snails and other hermits....and will kill each other...well at least from my experience....
I had plenty of shells for mine and a blue legged killed my nice red scarlet hermit for its shell then decided it didnt want it and took another...:arg:
