I'm not sure what kind of rotala it is. It was a RAOK to me. Looks like the Wallichii but not completely green. Almost like a rotundifolia with green on the tops of the leaves and pink on the underside. It's a pain in the butt to post pics to TPT from my phone but i'll see what i can do. I also have hydrocotyle leucocephala and frogbit i can cull out.
