Hitchicker Snail ID - Fish Killer?

[SoulFish]

Saw this guy crawlin on my mushrooms that I picked up yesterday. Is this something to worry about? Or is it harmless? It's pretty small, maybe only about 1/16"-1/32" After seeing it it slid around the rock not to be seen again.

Is this the really nasty harpoon type snail (fish and people killer) or just a innocent snail that can stay in the tank?

Looks like an olive snail, not sure specific species. But, I can tell you its predatory.

Yup think it's "Lettered Olive Snail" looks like this. Found off South Carolina, Florida. Predatory I think.. the one thick tube in front may be the give away.

I lived in Fl for more then 20 years, I use to collect them. The coloration of that specific one isnt the same of those I've collected.

It actually looks more like a marginellid to me. Probably Hyalina or Volvatella. It will stay small and won't pose any issues in the tank.

As Greenbean says, it's a marginellid. I thinks it's in the genus Volvarina, but there are several similar species found around the world. You could narrow it down if you had a good idea where the snail originated. It won't eat your fishies, at least, not while they are alive.

The pics of V. philippinarum don't look all that similar to your snail, but some variations are strongly banded and look almost exactly like yours.

Doh...Volvarina. Volvatella is a slug.

I figured you meant Volvarina. I'm prone to do the same thing, especially if I'm answering posts late late at night.

Cheers,
