we're doing quite well with golden pothos in several of our tanks (it's a kind of ivy that's often grown in a pitcher of water, apparently the roots do best submerged that way) we just place it in the tanks, and with proper lighting the stems will bend over a couple of days till all the leaves are at the surface of the water, providing lovely bubblenesting sites. it's also wonderful for your water quality, the roots soak up ammonia like sponges!
p.s. a woman at my work grows insane quantities of pothos so we get it for free, but if you're not that lucky it's available pretty cheap at just about any garden store.
