Need suggestions for floating plants

[Herpin Man]

I need suggestions for floating plants to put in my paludarium.
The paludarium is 4' x 8' x 6' tall. The lighting is 3' or so above the surface of the water, and appears to be sufficient for the terrestrial plants. However, I have tried water hyacinth and water lettuce, and I can't keep them alive, presumably due to the distance from the light.
I have a large water surface area that I would like to cover with floating plants.
Any ideas?

Iv always had great luck with java moss and duck weed. very hardy tough plants. my sliders tear up their tank continuously n cant seem to kill them. my frogs n toads love to float onto of the clumps of moss n peek up threw the duck weed. have to watch moss it will take over easy and plug up filter if not careful. jen
