I found a few threads where people were trying to ID it, and one person who said they had it.
I was gifted with it a month ago. Have it tied to some driftwood, not far from the filter outflow, since I've read they grow best with some current.
Any particular suggestions for the plant in a low-tech 20 gallon long? I dose with Flourish 2-3 times a week, API Leaf Zone, and API Co2 Booster every other day (there's anacharis in the tank, and more carbon makes it melt).
Here's a photo. (Pardon the shadows, the way the tank is positioned, it's almost impossible to get good shots of it except at night.)
