And on that type of substrate. Most corys reach 3 inches or more, and since they need to be kept in a group...as you can imagine, that will overstock very quickly and they'll all be crammed for space. I would also be leery of tetras as they can also get to 2-3 inches, and again, a group will easily overstock a 10.
Off the top of my head all I can think of are male guppies or a betta fish. A ten gallon, unfortunately, doesn't have much space.
