Update. I added some dwarf hairgrass in the front. I may break it down into 2 or 3 smaller clumps. Dwarf SAG in the back left corner has it's first runner off the main plant. Argentine sword is slowly growing in the front.
I am hopefully getting an anubias petite this week, but am still looking for another small piece of driftwood. Once I get that I plan to remove the water lettuce and more of the duckweed. Have had two batches of RCS hatch in the past several weeks as well.
