Terrestrial or aquatic moss for wabi kusa?

[Nick_593]

Hi as title, would terrestrial moss or aquatic moss be best suited for a wabi kusa?

Thanks

Several of the "aquatic"mosses will do very fine Wabi Kusa style.........Fissidens and Fontinalis not included, though. Monosolenium and Riccia works well, too, by the way.
