Thanks everyone, here's a little more info
First off, I hate the Bacopa too. It was included as an "extra" in with some plants that I bought. I'd never grown it before so I just threw it in there and gave it a try. Not only is it poorly placed, I really just don't care for the plant, period. It's gone.
The little sprig of stargrass on the left is actually an interesting story. Maybe two years ago, I had a nice stand of stargrass in this tank, but then I let this tank sat empty and neglected for about a year. I just turned the lights out and completely abandoned it. When I finally decided to rescape the tank, everything in was dead with the exception of an Anubias Nana that was doing just fine. I decided to remove all the Fluorite and try Tom Barr's suggestion of placing a thin layer of peat down on the bottom before putting the Fluorite back in. But when the tank was replanted, these little sprigs of grass started popping up everywhere. At first, I thought that the peat must have been contaminated with some sort of terrestrial grass seed, so I used tweezers to remove all the sprigs that I could. Finally, I decided to see how long this "terrestrial" grass could survive underwater. I'm sure that you've already guessed that it wasn't a terrestrial grass at all, and I was removing little sprigs of stargrass that were coming up everywhere in my tank.
I don't have any idea of where they came from. Either the stargrass had flowered and made seeds, (I've seen it flower frequently above the water) or tiny pieces of the roots were still alive and setting there dormant in the gravel. At any rate, that little sprig on the left is just one that I've yet to use the tweezers on.
As for the Tonina, I received that as an extra too. I kind of like it, so I'm trying to propagate it. Right now, my main priority is just to get some more of it. I'll worry about aquascaping it later.
The foreground plant is Glossostigma Elatinoides. I bought some Hemianthus Callitrichoides for this tank, but even after paying $25 to have it shipped overnight, it still arrived as mush. I still want to obtain some of that plant, but I guess I'll have to wait until the weather cools off before trying to have it shipped again.
