If you bought a Compact Flourescent of about 8-10 watts, you could probably grow nearly any plant you wanted.
Some particularly easy ones are:
Java Fern (tie it to something like rocks or DW)
Java Moss (same as above, I have bad luck with it though)
Anubian Nana (might be too big, same as above)
Egeria Densa/Anacharis (plant cuttings in the substrate)
You typically will be limited to foreground plants in a small tank. (I have dwarf sag, normally a foreground plant, as a tall middleground plant in my 5G)
Dwarf Baby Tears would be nice, but requires a LOT of light... have to be careful with high-light plants, since they are always high-nutrient and high-co2 as well.
Everything in proportion.
May I reccomend a school of Ember Tetras or Nortons Lamp-eye?
They're small enough that you could have 6 in the tank.
(I know, because Byron and Angel (respectively) reccomended the same for MY 5G :)
Always throw some inverts to keep it clean as well...
If you order from Sweet Aquatics, (great company, cheap stuff!) you can ask for some free snails in the comments area... They can give you ramshorns MTS and pond snails for free.)
If you decide to go with the single dwarf puffer, get extra pond snails... the puffer will eat the baby ones. :)
