I love how we all inspire each other! I remember the stands but for some reason I did not act on it. But after seeing your picture I did a quick online search and have fallen in love with this one: https://www.ebay.de/itm/1x-Aquarium...144431?hash=item43f16b376f:g:JRwAAOSwiONYQBMqThank you! I wish I could take complete credit for the idea, but another member inspired me just the same! I think he did some custom stands with them. These in total cost me just over $10 at PetSmart in the aquarium aisle! Definitely worth your time to stop and check. There's some really trippy and super "cheesey" alien plants there!
A friend of mine who does pictures with the 6" scale has some of aquarium greek columns and stuff. Last time I was in a shop I focussed more on these, but these displays can be quite expensive and also are too small for 12" scale so I didn't buy any.
Maybe if you can find some pebbles to put onto your "floor" so that the glass shelf isn't as visible? Or one of those mats that look like grass. I have one that is exactly the size to fit into a Detolf. Sorry for the offtopic figures, once the Star Trek team has grown I'll make sure to let them do a 4th of July barbecue:
