What is this pleco? I posted this in another forum, but had tons of ID's and no one is really sure of it. Let me know. Thanks! (sorry for the bad pics)

Also these fishes are white and black. One of them is a little gray on the body, but when active or feeding it turns white again.

looks a little like 333?

I would say more than a little like L333 and say it is L333.
I have several hundred of F1 L333 from newly released fry to some which are 2-3/4 inches and they are identical.
