Multiple Species of Cory

OK, so does anyone have any idea of what type of cory (if it is indeed a cory) it would be.

The fish that I was looking at was about 2.5 - 3 inches. A very dark brown with very fine lines of tan. The fins were the same dark brown color. I didn't think to count barbels or anything.
 
Got pics? Cories are as hard (or harder) to identify as Plecos are. There are so may similar looking species.
