Cerithium and blue legged hermit cohabitation.

[M. Tournesol]

I bought 5 blue legged hermits thinking they will stay relatively small... After some reflection (and growing of the hermits), 3 hermits would have been enough. Thus, I plan to relocate the two of them in my other nano starting with the biggest one.

 

My question is the following, will the blue legged hermit maim cerithiums that have too small of a shell for them? (PS: the hermits will have enough big shells to play with)

generally, I wouldn't think the hermit will go after a smaller ceriths where the shells won't be useful to it.  but some hermits are just murderous a-holes, so you never know.
