Covering the bare spots?

Depending on your tank setup i would just fill in with some easy plants.

mid to background
Wisteria
Green Hygro (looking for some myself)
LUDWIGIA repens or narrow leaf
crypts
anachris(spelling?)
spiral vals
watersprite

Foregroud
anubias
dwarf sag
crypts
java fern
java moss on wood or rock
chain sword

Tons more, just some of the staples you'll find around.
 
Depending on your lighting, maybe hairgrass, HC, Glosso......They'll do better with med-high lighting and co2 and make a nice carpet.
