I had somethig similar (bought 2 or 3 from Al's) not sure what kind of Conch they were but they killed and ate my Turban snails, they do disappear into the sand bed, but every so often I would see them attached to a snail and its mouth is inside the snails trap door and its game over for that snail.
Not sure what kind of Conch I bought but I am leary now.
