Do I have a common pleco/SAE?

Ok when I first set up my tank I bought a pleco, didn't know anything about them at the time and a few SAE's or what was suppose to be SAE anyway, now that I've learned more about fish and how big the Common get's and that most SAE in LFS are not SAE I thought I'd post pic's and find out what I have

I couldn't get a pic of the other, but it looks the same except it has a horizontal line going down the side of it's body.

Thanks guys/gals!!

Do you mean the SAE ones are plecos? Or do you mean the plecos I have are different ones? I have a couple more pics if needed.

BTW: WOW that was FAST, I posted went and looked at another thread and POW I had been answered (your so awsome )!!!!!!

I finally got a pic of the one that I couldn't get a pic of before but from the pic that rockabilly added I know it is a CAE! D*mb it!! Aren't those the ones that get really aggressive and stop eating algae once they are older?

I know the common can get that big (now), that is why I wanted to find out what they were too the biggest tank I am going to have for a while is a 75 (well until around Jan), then I plan on getting a 125 but I have 2 of these guy's one looks slightly different than the other (the edges of the fins on one is more rust than the other one) I will have to find homes for them I think...none of the lfs around here will take fish from you. CRAP!!

Wow as many times as I have been to this site and I never noticed the "catfish/bottom feeders" thread!!! Sorry I will move my question on to that section (if a mod or someone could just move this over there I'd apprechiete that!)

Thanks,
Gin
