I also thought that maybe I could just leave it with moss, the lotus, and put something like the chain swords or parva in the foreground and just let them slowly fill out a "carpet". Maybe put some vals in at the back to make a wall?
that sounds pretty good.
When I first read Tiger lotus I imagined it in the V of the wood more towards the middle of the tank with the Rotala or anarchis in the back with the wood mossed out with a carpeting plant to fill in the foreground.
Whatever you do it looks like its going to be a sweet little nano. Look forward to updates.
