Matt you should try to get a plant that dosn't require any CO2.. ray set-ups usually have a high amount of dissolved oxygen to support nitrifying bacteria. Which in turns, releases Co2 making it virtually impossible to grow fully submersed plants. I would try Anubias or Java Fern, possibly mounted high up on some driftwood in the main display..
The others are things like pothos and floating water lily..

I had good luck with these.. but I failed to recognize the fact that when plants go to 'rest' at night, they consume oxygen.. couldnt figure out why my fish were splashing at night.. ended up killing a Jardini... might have an airstone on a timer to add o2 at night..
