Hitchhiker ID?

[Jamie9]

Found a tiny snail baby on my glass today. It's like, the size of an amphipod, had to break out the DSLR and manual focus just to get a decent shot. Any idea if it is friend or foe? I assume it came in on my live rock in egg form, as the only snails I currently have are trochus...and this doesn't look like one of those to me.

TBS replied nice and fast to an email I sent this morning. They are thinking cerith snail. It'll be fun to see if it grows up.

Found another hitch hiker this morning (photo below). It was crawling on my rock when I turned the lights on in my office and it started making a run for cover. I'm pretty sure it's some kind of whelk so I pulled him out of there. He can go in a little bowl for my son to watch for a little bit...but destined to be bird food I think. I'm glad I found it now as I have a 5-pack of small Nasarius snails on the way and not sure I'd have been able to differentiate it from them.
