one last bump! Don't want to be a pest, but I learn so much from these forums!
Right now, this is still the plan: For now I am picturing Aponogeton longiplumulosus in the back left corner (behind the Beast) and Aponogeton ulvaceus right-of-center, just behind that edge of the rock work. The rest of the back right side will be jungle Val. In the mid areas, between the driftwood pieces (spaces are hard to see in the pictures) I will have ambulia, Nesaea crassicaulis, and Nesaea pedicellata 'Golden'. For the foreground I am thinking of either 10-12 sprigs of dwarf Sagittarius (still leaving the center "path" to the rocks open) or plant some star grass and keep it trimmed down low.
I have decided against the crypt parva.
I would also love a few Downoi, but I can't find any anywhere.
Just an old dog trying to learn some new tricks...
