Rasboras and danios would be my pick. Nice school of 10 or so . Lots of pretty species. Avoid barbs and most tetras with your long, flowy-finned fish, as they can be fiin nippers.
You could also add a couple true siamensis algae eaters. But be sure to get the true siamensis and not Chhinese algae eaters, which get large and aggressive.
Most small, peaceful community fish would do fine with your stock.
