Need Plant advice please

They're doing great! growing up to be beautiful.
It was interesting to watch how they formed their own little pack when introduced to the bigger fish. I have a huge pink kisser, about 6"and a silver dollar about the same size, that immediately became babysitters. I really thought those 2 would be the ones to cause problems because they are the biggest and oldest.
 
I would avoid duckweed. It is very small and VERY hard to rid yourself of when you try. It will get all over your arm when you reach in your tank.

I like frogbit and salviana but some of these floating plants are illegal as they are on the federal noxious weed list so its something to be aware of. No experience with red root but it sounds cool :)

I have that junk all over my tank, Im not even sure where it came from!
