If you're going to get a pleco get it because you want one as a tankmate. NOT to clean algae or leftover food or anything like that. I have had them survive fine at room temp, of course my room temp might be lower than yours (low-high 70's). They are well armored and hardy enough that they should hold up well to most sunfish.
As for your food, I have never used it. I feed my sunfishes a variaty of food but as far as pellets go they mostly eat Omega One cichlid pellets. They have a great list of ingrediants like whole salmon, herring, shrimp and fresh kelp.
