What kind of snails are these??

[CoralReeferGal]

Bought these advertised as nassarius snails... But they don't look like the ones we already have. Afraid they may be an unsafe welk... Can anyone tell what these are? Are they safe to add to our reef? Just spent THOUSANDS getting the tank back in order and dont want to risk putting something in that will eat our corals! Please help! Thanks in advance...

The one on the left is a Nassarius. The one on the right is a whelk.

Thank you!! Can you tell from this pic, are these ok to put in the tank or are these ones bad news?

You don't want the one on the right in your tank. The other should be fine.

What about the ones in the 2nd pic I posted, the snails in the baggie?

I can't really tell anything about those.
