Aquarium plants (Hollingdean)

I've reduced the spread of plants in my small tank. I've got some of the red leaved plant and some of the floating ones spare if anyone wants some. Not sure of the names. The red one roots really easily, roots emerging from multiple points of the stem. The floaty one (the larger of them) reproduces quite fast but is easy to scoop off and control. It has hanging roots which you can see at the top of the picture. (There is ordinary pond duckweed in there too which I wasn't offering but you can have if you want).

If you've got any other species of plant you can spare a bit of in return that would be great.
