I'm not convinced that emersed tanks are less colorful. Sure, some species tend not to display the same reds as they do underwater (Persicaria spp. 'Sao Paolo' and 'Kawagoeanum' are good examples of this), but there are plenty of species that still show vibrant colors in emersed culture... For instance, Nesaea, Rotala, and Lysimachia species all look lovely in my tubs.
Neil, want to swap seeds sometime? I'd love to get my hands on some Hygro lancea. I have plenty of Limnophila rugosa and maybe some Staurogyne sp. 'Bihar' seed pods I can spare.
...The other wonderful thing about seeds is that they can usually be mailed for the cost of a stamp
