is this a whelk?

[salty joe]

I put in some nassarius snails a year or so ago but they were tiny. This guy is a little over an inch. I've had snails disappear...is this a predatory whelk? Or a grown up nassarius? When he sticks his snout out, it's nearly as long as the snail.

Looks like a whelk to me.

Whelk indeed. His punishment shall be banishment to the sump.
