Coral banded shrimp agression?

[jhawk__]

I've been recently finding lots of my snails and hermits slipped on their backs and the shells look empty almost as if something eating them? Could it be my coral banded shrimp? Are they aggressive towards other inverts? Or could it be a lack of food for the shrimp which is making him turn toward my snails and hermits

Hermits will fight over bigger shells. Maybe adding some slightly larger snail shells will give the growing hermits new and larger homes.

My hermits are tiny tho I don't think they could be killing my Astraea snails? Or could they be? I thought it was my shrimp being the bad guy
