Doug is spot on here. Watersprite is a great plant for this. You'll have to trim it pretty frequently if you have anything like good lighting. It'll spread about a foot across (or more - front to back on a 55), and the roots hand down a good foot as well. It's a fern, so it spawns clone plants from the leaves. You can cut the bigger leaves and ditch them, or plant them and it may root and grow. The lovely thing is that it is also a total nitrate beast - it's one of those plants that for some reason would rather eat nitrate than ammonia - so it can help your tank to be more forgiving on water changes.
If there were an indipensible plant for a gourami tank, this would be it.
Another good one is Hygrophilia difformis - Water Wisteria. Same deal with Nitrates. It's not a floating plant, but it's grown to the surface in every tank I have it in (22" at most), and makes a nice umbrella-like crown. It also needs frequent trimming, and it spreads like mad, even under 1 watt per gallon. (Though it looks leggy when the light is low.)
