Is "Casper" a albino red eyed Plecostomus?

[skwerally]

I guess I just want to get my facts right on my plecostomus'. I have "Casper" who was sold to me as a red eyed pleco, I have been calling him an albino, hence his name "Casper". I also have "George" who is a pleco, but black with white spots. The pic of him is a little fuzzy, but would like to also know his correct name. I only have 3 fish in the tank, Sylvester (Oxydoras niger), Casper & George. I feed them all shrimp & whitefish (fresh) and I have them in a 55 gal, with 2 heavy duty filters. I've had all 3 for aprx 10 yrs and would like to keep them healthy. I Don't know any of their aprx life spans. Also, I've read some like to eat frozen peas?
Any info would be appreciated. Thank you!

Casper is

Pterygoplichthys pardalis

and
George is probably the same.
