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.

As far as I know they are, but like I said - I'm just a hobbist and a lazy one at that. I have had no problems with my red footed conch that I'm aware of. Mine mostly sits in one place for long periods of time, he will disappear for weeks in my rocks. He also doesn't grow very fast as compared to my fighting conch.

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
