I'd please, it's not a nassarius.

Found this little guy. Has almost calcium like tubes, no elongated snout or tail, very compact body under the shell.

Can we see the slug side or some different angles?

Take it out and get a better view of it at the side in a glass jar of saltwater while its movin about, could be a whelk, conch or dove snail, or some other kind of nassarius snail in the family Dog Whelks

My first impression based on the numerous layers/ridges visible on the snail is some kind of Muricid snail, but - as mentioned - closer pics of the top (straight on), side(s) (straight on), and bottom (straight on) would be helpful for ID attempts.

Yeah, I don't know the species, but there's a very good chance that's a predatory snail. So, you probably don't want it in your display (it'll probably eat your CUC snails).
