Any of swords, crypts, sag, or vals would work. Also, any of the anubius sp varieties or java fern varieties. Crinums are a great choice as they are a bulb plant and very undemanding. If your tank is bare bottom then a flower pot with some potting soil under a layer of gravel would work. Floating plants like guppy grass or wisteria too.
This 29g is planted with dwarf sag and Crypt Wendetii Bronze.
