yah, I have had no luck with this plant either.
I almost wonder....if you get new plants, would it be better to cut off all of the leafs, plant it, and let new leafs form from the nearly bare stem? I bet it wouldn't float as much that way....
i always trim off a few sets of leaves, not the whole stem. i leave about a quarter of the leaves i cut. that makes it easier to plant and less apt to uproot.
as to the op, looks like yours took a beating during shipping. no light tends to make the leaves translucent. it should bounce back, give it time. pretty hardy plant ime and grows like a weed; i toss a handful every month or so in my compost pile.
