My personal preference for a 24 gal tank, would be a pair of purple firefish, they are fairly colorful and spend quite a bit of time hovering in the water column.
As to a substrate cleaner try a dragon goby, or two spot goby (I can't remember to suggested tank size for these guys, but they are smaller than the dragon gobies, so should work). Or you can go with a sand sifting snail, but you'll never see him.
