Right now I've got a "common" pleco in my 60 gallon tank. I know he'll eventually(or soon, he's growing fast!) outgrow it. I was planning on getting a huge tank(at least 125 gal.) for him and a couple of cichlids that I had, but that plan isn't going to be able to happen, so I'm keeping the 60, yet don't want to cram my plec in it.
So my question. Can anybody recomend a pleco(I dunno, would rather have one of them, I like them

) that would stay small enough for that tank. Preferably a larg-ish variety though since it would be sharing a tank with an oscar. And also preferably one that isn't too costly...
edit: oops, also forgot to add... Right now mine is getting leftovers from my oscar's dinner(meat and veggies mixed) spinach, algae wafers and shrimp pellets. So if I could find one that eats at least the meat and veggie portion it'd be best, though I can also adapt what I'm feeding for it too.
