The reddish one is Rotala wallichii. Certainly not Ceratophyllum.
The other I'm not quite sure of. Kinda looks like Rotala mexicana 'green'. Are there tiny vertical grooves on the stem? It would be pretty odd to get a rare, specialty plant like that as a toss in though. Other possibility is Pogostemon, and that's probably more likely.
Where did you get it?
