hey guys,

i was watching my inverts since my clown is still in QT, and noticed that my green emerald crab was being very aggressive towards my hermits, to the point he would clamp his claws at them and pick and move them around briefly. i came back a few hours later and noticed an empty shell at the base of the rock where my crab hangs out and tiny legs around the area. im assuming the crab kill the hermit.

do these crabs do this often? if so is there anyway to stop him, he is fed by hand so im sure he is not hungry.
