Yeah, those are papillae on the mantle (they inflate and deflate, like the little dendritic structures on some cowries). I don't know if they serve...
It's a good idea to use caution with introducing things you aren't sure about into your aquarium. But, with the exceptions of the reserves, and the...
I just realized there was a second snail visible in the third pic that isn't a Busycon. I think the angle of the photo is making it look more...
lol, thanks will
Lightning whelks, Busycon sinistrum. They are predatory, of course. Busycon sinistrum Cheers, Don
Well, sorry to hear about that. The nudi's won't live that long without food, maybe a month or so. Some nudibranchs have longer life cycles, but...
Nah, whichever it is, it won't hurt anything.
I'm sure you're right about it being a bivalve. Hard to guess which one without killing it and cleaning it, though. You can find both mussels and...
I don't know for sure, but they must spend quite a bit of time out of sight, otherwise the collectors and sellers would probably remove them. You...
Here I stumble, but not with very good news. It's an arminid nudibranch and feeds on soft corals. That particular one seems to come in fairly often...
Well, it might. Several families are prone to do that as juveniles, including columbellids, triphorids, eulimids (yours are none of those) and...
Yeah, from that view it looks like if it has a siphonal canal it's very short. Wentletraps don't have one at all, but the lip is sometimes extended...
No, I was referring to the other link. Yours are correctly identified. I would have spent more time looking for them on zoanthids if I'd realized...
I'd be interested in seeing a larger pic of the snail. Can you just crop that pic so that it shows up with more snail in the pic and less...

They are, for sure, Nassarius vibex: Nassarius vibex (Say, 1822) - Bruised Nassa They aren't truly tropical, but much of their range...
My kids caught a bunch of them last week under the bridge on the west side of Destin. They are actually Nassarius vibex, not Ilyanassa, the same...
Mike has it right, it's a tritoniid nudibranch, and not one that you'll want in the tank unless you prefer the nudi to the host species. You can...
I think I'm looking at the end of a true mussel. It shouldn't be a problem. Cheers, Don
Ilyanassa obsoleta.
