Snail ID pls

[jgraz]

Had to wake up early for work today and I got a look at my tank at 4:30am. I counted 21 of these guys.
What kind of snails are they, are they collonista's? All are about the 1/2 the size of a pea and smaller. Needless to say I have never added them myself. I have never noticed them before, though its been awhile since I took the time to search around in the dark. Also noticed my long lost peppermint shrimp. The last time I seen him was when I put him in the tank.......in october. Since then all I have seen was his molt about 1 week after that.
Here is the pic of the snail. Hope its good enough.

Could be collumbellid's, would need a better picture. But here's an article that might shed some light:

Collonista's can be found here:

The pic isn't very clear. Does it have a small cap as a shell John? If so, it looks like a stomatella snail. Those are good (if it is one).

I can't remember the name off hand, I'll look around to see if I can find the name.

EDIT: Fount it, they are called Collonista Snails.

They are nocturnal and hide in the rocks during the day, but occasionally you will find them out during the day.

They stay very small and they will reproduce in your tank. I started with 5 and now my rocks are covered with them at night.

Thanks Jim & Ray
Yeah the pic sucks. it was 4:30 this morning. hold a flashlight and my iPhone. Defiinatly not a stomatella, those I know. They appear mostly off white in color with some brownish/tan stripes. After checking some things Im really leaning toward the collonista snail but tonight I will try to get one out for a better pic.

Didn't see your post Brian. Im leaning that way too. I didn't add them myself guess they found their way in somehow.

Definitely collonista in that pic. I had dozens of them come in on the LR of my first tank. When they're really small they tend to be all white, and the red mottling comes in as they get closer to pea-sized. They basically max out at about the size of a pea.
