Tonight I received my foreground plants from Sean (sjb1987) in the SNS forums here. I am very happy with both the quantity and quality! The main foreground plant is Marsilea
quadrifolia, and then there is a little Hydrocotyle Tripartita Japan sprinkled in (and running up the driftwood).
Here is how it looks. Sorry for all the bubbles and cloudy water — I just finished planting them and I'm too impatient to wait for it all to clear up.
It should fill in nicely over the coming months.
