I recently set up a 20 gallon 16" high tank, and it will be for the most
part a planted tank. I have a few things in it right now, but the only
name that springs to mind is WaterSprite (center of the tank), and 1
Anubias (not sure of which kind) that fills a corner and is the full height.

I am in search of some ground cover, but the lighting is what's going to
hurt me, from what I understand. 30 Watts total, 2 bulbs, 1 full
spectrum and 1 6700K. I am looking for something that will make a nice
carpet. I have the Eco black substrate in there now, but would be more
than happy if I could get it mostly covered in a nice carpet eventually.

Ideas? Suggestions?
