I can only comment from my own experiences:
Micranthemum micranthemaides - too invasive
Glossostigma elatinoides - too invasive
Lilaeopsis - might work; try L. brasiliensis
Hygrophilia - too invasive, most too big
wisteria (= Hygrophila difformis; see above)
Bacopa australis - too invasive, but might be good as initial fast-grower
African Fern - gets big
Hemianthus callitrichoides - perfect for small tank
Eleocharis acicularis - probably invasive, gets tall for tiny tank
Cladophora aegagrophila - nice idea!
Rotala wallichii - might work as background plant; try to find var. 'short leaf'
Micranthemum umbrosum - wonderful plant if you keep under control
Ludwigia brevipes - leaves get long
Crassula helmsii - ??? (never tried this plant, myself)
Vesularia dubyana - depends
Microsorum pteropus - plantlets would work but will get big
Anubias barteri nana - will get big; your lighting might be too strong
Sagittaria subulata (dwarf) - doesn't stay "dwarf" AFAIK
ludwigia palustris - too big
Rotala indica - might work as background plant; good fast-grower for initial set-up
Hemianthus micranthemoides - same as Micranthemum micranthemoides
taiwan moss - nice
junior sword plant - ?
Riccia fluitans - will work under your lighting, but will be fast-growing
Rotala rotundifolia - never figured out the difference between this and R. indica
xmas moss - ??? (never tried this plant, myself)
dwarf grass - Eleocharis parvula, I presume... Took over the whole tank in about 4 months.
Here are some to add to your list:
Lobelia cardinalis 'small-form'
Mayaca fluviatilis - didn't work for me, but you'll have stronger lighting than I do
Micranthemum sp. ("Amano pearlgrass" or "two-leafed hemianthus") - grows fast, but upwards, like M. umbrosum; easy to "corral" by snipping creepers
Ranalisma rostrata - still experimenting with this, myself; jury's still out
Lysimachia nummularia 'aurea'
Bacopa monnieri - (banned in many states but I see the stuff at Petco all the time)
Lindernia rotundifolia 'variegated'
Didiplis diandra - didn't work for me, but may grow fine with your lighting
Cryptocoryne parva - too dang slow for me
Elatine triandra (or other species) - needs LOTS of macros
If you didn't have such strong lighting, I'd recommend Anubias 'petit' - under strong lighting, Anubias tend to get crusted over quickly with green spot algae.
If you want a rosette, maybe consider Echinodorus parviflorus 'Tropica.' You'll have a hell of a time uprooting it, if you decide that you need to after it's already established roots.
There are also a few "new" varieties of Bacopas and Rotalas that are supposed to stay small, but I've never had luck with Rotalas and I haven't had a chance to try the rarer Bacopas. If you have really soft, acidic water, rich nutrients and good CO2, you can give Tonina fluviatilis a try. They need to be *behind* other plants to hide their rotting lower leaves. HOWEVER, they cannot be shaded over or the whole stem will die.
Good luck! I think you'll have fun with a tiny tank.
