Help on snail ID

[barmaley2003]

Hi everyone, I need ID on snail on the photos. Is it predatory whelk or something else. It came with LR in my tank and was pretty small then. Now it is much larger and I have suspicion that it ate part of my zoa's colony recently. Should I leave her in my tank (no sump unfortunately) or get rid of her?

It is a conch of some sort.

Nah, don't get rid of her, she's not eating your zoa's. It's not a conch, but it is an algae eater/detrivore. It doesn't look that much like a cerith, but that's actually what it is. It's a juvenile Cerithium echinatum, an Indo-Pacific species that gets up to about three inches long. If you look at the top half of the shells in this link, it will look the same as your snail:
