Thanks guys, Ive been reading up about Glosso Tropica say that it really prefers soft water, is it that picky?

Im leaning towards HC as its tollerences seem to be wider for a harder water. It also looks very like Glosso (from the pics anyway).

My tank is only 12inches wide unfortunatly, so the area I have to cover isnt that wide either, maybe 8 inches or so. Im definatly going to do something with caves though Tom as you suggest, probably with some java moss as I have some of that already (still young to the tank, but its started whooshing now nicely).
