If you go with the pygmy cories you could have a whole little school of 4 to 6 in the bottom of a 20G and they're every bit as industrious as the larger guys (heck I even find mine more active then my peppered).

They're nocturnal (in theory, though I find cories are often active in the day too) and so they need some shelter to hid in during the day light hours. Also you'll need some algae wafers and maybe the occational sinking pellet for them depending on how much food gets to the bottom and how much plant life is in your tank.
