I'll second the vote for the Otos. Just about any species is good. Right now I have several Tiger Otos doing algae duty in my tanks as well as some regular otos. Hypoptoma gulare is a bigger and more unusual version but very similar and a great algae eater. I'm hoping to get some Paraotocinclus maculicauda soon and I'll see how they do.
