Any that will eat the brown alge?

[wwestar2000]

I have a 20 gallon with 6 cichlids in it. It will be 4 soon after i get a pair. Oh and its 3 angels 3 keyholes (Juvie's). Ok My tank sits 25% trough a windo. The blinds are always closed but i get a brown alge on one side. Im gonna buy a alge scrapper but The alge is starting to grow on the gravel. Any small fish that will 1)Not turn aggresive toward my other fish. 2) Not a rubbernose plec(can never find them) 3) Will help control the brown alge that forms on the gravel. I had cories in the tank (for a note i know they don't eat alge) And there fins were getting nipped. So there gonna have to be smarter than cry's.... yeah so any suggestions?

I have had some success with livebearers, but even they won't eat the stuff if there is anything nicer tasting to be had. Can't be very succulent stuff, nobody seems to like it. Maybe a snail?
