IMO you should go:
6 otos
10 Harlequin Rasboras
or
6 Cherry Barbs
or
10 Cardinals, Neons, Rummy Nose, Bloodfin, or Bleeding Heart Tetras
8 Kuhli Loaches
Your mollies
Dwarf cichlids would be suitible for your tank, but they would fight the loaches for territory on the bottom. I think Bolivian Rams are your best bet.
Or, if you want a really good tank
25x Kuhli Loaches
1x Betta
Good 'nuff
