Have you checked the FAQ? It is by no means an exhaustive list but is a place to start

What type of lighting do you plan to use? Also, is there anything you're gearing for in particular? Are you modifying the screen top that came with it (I took mine off and replaced with glass instead). Also will there be any animals in there? All of these (and a few others) have to be taken into consideration before deciding on your plants. Or you could always pick your favorite plants, and plan around them instead!

I have a glass lid for it and will use a small floro light (coralife mini) for lights. Might want to add a gecko, but I dont know.

I guess i wont do anything.
