For plants that need no CO2, best bet would go to mosses, nanas, cryts and hair grass. My fav still lies with mosses since it is not only hardy, but relatively easy to plant, can be used as background, midground and foreground plants, depending on how you decide to plant them. Nanas go very well with mosses while crypts have a tendency to develop crypt rots. Hair grass grows extremely slow without sufficient light and CO2 but alas they grow. Need to trim once in a while to prevent algae from forming though.

I think riccia should be able to grow, but i am not quite sure about it since i only started to plant them recently.

Cheers,
