8g nano tank - substrate carpet suggestions
 

Well due to the shipper sending me an 8g tank instead of a 4g tank I now have plenty of room for a decent layer of substrate. I'm getting in some very dark black/midnight blue stones and some white stones along with a small tangle of rosewood.

The light with the aquarium gives 20 - 50 par at 12" and 50 - 80 par at 6". I was wondering what plants I could use to cover the substrate and then place the stones in and among the plants to form a boulder like appearance with them.

I have no experience with co2 except for using excel, and probably need a relatively hardy plant.
