Beautiful tank! I totally understand the logic behind utilitarian fishrooms, but I've always loved show tanks that are of the 'piece of furniture' school of fishkeeping. The Juwel setups are stunning, and you've done a great job with the decor, plants, and fishes. I'm not sure that all of the plants you've chosen are going to thrive in hard water, but if you do lose some of them, I would suggest that you consider replacing them with Anubias
. There are many different species avaiable, and you can just glue them to your rocks.
Have fun, and enjoy your tank!
