Hey Todd will they pick on inverts?
I know I'm not Todd...but just to throw my .02 in there
My yellow coris ignores most of my snails and cleaner shrimp...he's actually let the cleaner hop on his back a couple times. I had a hermit crab leave his shell to find a new home and the yellow coris pounced on him almost immediately. The only snails he tends to pick on are the smaller nassarius snails, likely because they have much less protection than some of the others in the tank, and they like to stick those feelers out of the top of the sandbed.
All that being said, I started feeding my tank 2-3 times a day rather than once a day, and he's since completely ignored all of my nassarius snails and hermits. I haven't been lucky enough to witness any more hermits switching shells, but I've noticed the 2 that I have did switch shells at one point and survived the ordeal.
