Identification Help

[Chitownpw]

I'm trying to identify what is in the attached pic. I didn't recognize it at first so i removed some from my tank, but i'm wondering now if it is a nassarius snail (I have some in my tank). Any help would be appreciated.

It looks more like a flatworm to me. (Polyclad?) What's the other side of it look like?
