I think the display would be cool. I saw a really cool display fuge like setup somewhere online. The display was to either side of the tank display and had a huge mangrove growing up and out of the water. About five feet tall or so. There were a couple of LR littered about the bottom and the root system for the tree was just over the top of the water.

It was like two huge (30 gallons?) glass flowerpots that housed two mangroves, one each. I believe there were one or two fish in the pots as well.
