Hi all, anyone can help ID this plant?

Pista stratiotes, commonly known as water lettuce

I see. I bought wrongly from LFS and it looks like its dying. Does it need alot of light and co2? Mine is a low tech tank only.

CO2 is not critical as floating plants can take in CO2 from the air. It requires high levels of light and is most often used in ponds, where sunlight is utilized.
