Thanks everyone! I'm thinking its most likely the alternanthera reineckii. I have have 85 watts on a 37 gallon so it will interesting to see how it does. It's also interesting the differences of opinion on whether its an aquatic, not an aquatic but may do well long term, or won't last long at all. I usually try stay away from the non aquatics, but the lfs assured me it was an aquatic (even though they didn't know what it was!) Typical.
