Minimum 30+ stems of Rotala (8"-12" length) and a 5"x5" mass of Riccia Fluitans. Many of the Rotala are also multi-stem plants already. Looking to get $20 for the bunch (Riccia and Rotala). I'm not sure on the exact Rotala species. The leaves are bright green now, but when I had them floating in another tank, they were very orange/yellow/red. I use low-med light, so if you have med-high light, they will redden up.
Here's a pic from a few months ago, with some of the Rotala floating next to a Riccia bunch (click pic to enlarge)-
