I just got a co2 kit so I can get the dhg to carpet. I'll probably pull out the pot later on just have it so the fry can hide. I have a nice size piece of driftwood behind the pot you can't really see in the pic.
Moss, anubias or fissiden on the driftwood would look good. Cut the stems in half and replant them, promote new growth. I would pull up the DHG and split up the clumps. Then replant smaller groupings, it will spread much faster.
