Sorry, can't give an ID. But I'd say this is definitely a case of guilt by association. It was probably on the hammer for a reason
![]() Remove to sump/QT and await positive ID.

It looks like some sort of conch, but I certainly couldn't say for sure. Most snails are pretty harmless. As a matter of fact, the only snail I think I've heard of that's an issue in a reef tank is the sundial snail, and that's certainly not one of those. If it is a conch, the biggest issue with those is that most of themy get far to big for a home aquarium.

I don't know, but it looks a little like a whelk, all of which are predatory. There are many predatory/non-reefsafe snails, thankfully they don't often come as hitchhikers.

I don't think your hammer coral has much to fear from this guy, but some of your other inhabitants might. Can you get a pic of him so that I can see the length of the shell compared to the width? I can't tell from your single pic, but I'm pretty sure it's a fasciolariid, the same family that contains the predatory Horse Conchs and Tulip Snails. They aren't true whelks, but they are very effective snail killers. Even though I can't tell if your shell is "nobby," it looks like it might have the stripe that would make it a species of Leucozonia, and it may be Leucozonia nassa, a Florida/Caribbean species. If you want to bother with posting some other views of the shell, I can probably give you an accurate ID.
Cheers, Don |

Whelk was the first thing that popped into my head.

I also thought Whelk.
I bought a whelk once, being told by my LFS that it was a conch. It devastated my snail population, and kept looking for more. It was cool to watch, of course, before I knew that's why my guys were dying, but eventually I ended up with no snails. I would have pulled him out immediately if I knew it was a whelk and that would have saved me spending double on my snails. (On a side note, LPS did NOT replace my snails.. ![]()

Looks very similar to my "Red Footed" conch. But I wouldn't trust myself - so good luck with finding out what it is.

Pleuroploca australasia
Flush it, it is a predator. http://www.gastropods.com/4/Shell_4784.html http://www.woodbridge.tased.edu.au/m...sea_snails.htm

The chances of this snail being Pleuroploca australasia are essentially nil, but the chances of it being in the same family (Fasciolariidae) are about 99%. P. australasia is an Australian endemic, and few, if any, are imported into the U.S. alive. It's also a less inflated shell than the one in the photo at the top of this page. I wouldn't flush any cool animal, including this one, unless I knew it was likely to do something I didn't want it to do, like eat all my other snails... Even then, I would freeze it and keep the shell rather than flushing it.
Cheers, Don |
