big mouth flattish brown snail without a shell sea slug looking thing?

[willie]

came out of a new rock i just added, didnt know it was there until I turned on the light and saw it move quickly back to its lair. I tried to get his picture but he was a quick little dude. about an inch and a half long with 2 eyes and im not sure what he is?

It could be some kind of a hitchhiker sea slug.

Without pictures it's hard to tell, slugs are not quick...from what you discribed, maybe an isopod.

Sounds to me like some type of Bubble Snail. I would need a more detailed description or a picture to positively ID. It's too long to be a Stomatella varians.

no legs so def not isopod, it is a gastropod of some type. when I described it to the guy at my lfs he said it was a type of snail that has a flat shell. I have not seen him all week so no pic attempt yet but I do have my camera by the tank at the ready.

The type of snail that has a flat shell is a Stomatella. I do not believe they get to 1.5". I suppose anything's possible.

Good call Bangguy it is most def a stomatella. I may have been off a bit on size...when I saw it it was brief and he quickly disappeared. Actually havent seen him since.

Had you said 3/4" or even 1" Stomatella would have been at the top of my guess list.
They are perhaps one of the most useful snails for diatom control.
