Sounds interesting Rex especially with the java fern, I think though that if you stuck cork onto the tank rear then planted with java this would give a submerged buttress look to it.
Anyway you will no doubt form your own opinion.
Incidently went to your site, thought it was informative and somewhat amusing. Thought being banned for use of the S***t word was a bit rough, and the comment you made was not that insulting, have had worse said to myself.
Anyway best of luck with the new tank.
