Help me ID this pleco please...

[Tasha]

I purchased a used tank awhile back and this guy was in there with some guppies, (its suppose to be my QT tank)

Hes about 3.5-4 inches long. Hes very shy and hides most of the time under some driftwood I put in there. Rarely have I seen him on the glass... I was cleaning the tank this morning and got a couple pics of him, although not the best I hope they help.

??

ignore the baby guppy infront of him in this picture.

Looks like a common Pleco to me, but there are so many types it's hard for me to tell for sure.
