Hi all,
Same as the others really Anubias, Java Fern, Java moss as attached plants, Cryptocorynes and Amazon Sword (Echinodorus bleheri is easiest) as rosettes, Cabomba caroliniana, Hygrophila corymbosa & Rotala rotundifolia as stem plants and either Amazon Frogbit or Floating Fern (Salvinia) as a floater (although both FF and I quite like Duckweed). Other good ones that float below the surface, but aren't usually rooted, are Indian Fern (Ceratopteris) and Hornwort (Ceratophyllum).
For Vallis it really depends upon your water, if it is soft it won't do very well, but if your water is harder it will grow like a weed.
You can PM me if you got any questions.
Cheers Darrel
