yeloow clown goby killing snails?

[WHiteout]

i came home today to see my yellow clown goby munching on a dead nassarius snail.

the shell was flipped over and snail parts are all over the floor. could it have been a hermit? i think it could have been the snail falling on its back.

any ideas?

nassarius snails can easily flip back over, so it didnt die just because it was flipped.

most likely a hermit did get to it and pulled it out, and the yellow clown goby ate the free food.
