My vote DEFINITELY also for Hygrophila polysperma. I bought some a few weeks ago and one stem grew from 6 inches to 20 inches in two weeks (with no CO2). I couldn't believe it. I now have it chopped up and planted as four separate stems. Brilliant stuff...and very attractive in high light set-ups as it can go pink at the tops."Somewhere, something incredible is waiting to be known." Carl Sagan

That's what I did in my old 10gal 3.6wpg tank. It grew like a weed. Now I have it in a 10gal 1.1wpg tank, lit by a single spiral CFL 11w bulb. It's raised about 2-3" from the tank, though... not right on top like previously - and it's on an angle. Pretty horrible lighting - barely any visible growth.
