I had a nano tank open up and decided that I wanted to scape a native US biotope. I have never kept live-bearers and so, given the small size of the tank, I decided to stock it with Least Killifish, Eastern Grass Shrimp, and Ramshorn Snails. After doing a lot of research (sources below), I came up with a rather comprehensive list of plants, collected hardscape, and started scaping the tank. Here's my journal; I'll do my best to keep up on updates.

SOURCES
Guide to Common Wetland Plants of North Carolina (NC DWR 2021)
Common Wetland Plants of North Carolina (NC DEQ 1997)
Occurrence of Least Killifish at the Northern Limit of its Range in South and North Carolina (Nelson and Burge 2014)
Ecosystems of the Cape Fear River Basin

TANK SPECS (updated 2021-07-18)
Aquarium: 7.5G Rimless Cube (Seapora, 12"x12"x12")
Light: Fluval Aquarium NANO Plant Spectrum LED
Filter: Marina Slim S15 HOB (course sponge, filter floss, bio rings)
Heater: None
Water: Conditioned tap water (Alexandria, VA)
Substrate: Seachem Flourite Dark
Hardscape: Collected creek stones, spare manzanita wood (via manzanita-driftwood.com), oak leaf litter (via Tannin Aquatics)
Planned Fauna: Least Kilifish (Heterandria formosa), Eastern Grass Shrimps (Palaemonetes paludosus), Wildtype Ramshorn Snails (unknown)
Planned Flora: Mayaca fluviatilis (shown), Juncus repens, Didiplis diandra or Ludwigia alternifolia, Lobelia cardinalis, Fontinalis antipyretica (Phoenix moss) or Fissidens fontanus (Willow moss), Azolla caroliniana (Mosquito fern), Spirodela polyrhiza (Giant duckweed)

I will be adding more hardscape and plants over the next month and will begin to add livestock once the plants have grown in.

Here is the tank so far (2021-07-18):

Nice looking tank, im in the GA so a biotope would be pretty similar in my area. The only suggestion I have is to add a background, I would do black. I used a poster board on the back of my 20g but you could paint it instead if you wanted too.

2021-08-08 Update: I went on vacation for a couple weeks and when I came back the tank was cycled and full of algae. I did a water change, cleaned out some algae, and added a ramshorn snail. Plants are growing well and I will be adding the rest of them early this week. Fish and shrimp to come!

2021-08-26 Update: I'm having a hard time getting a good picture of this tank, but it's safe to say that this is my new favorite. Since my last update, I have added plants, let everything fill in some, and added livestock. Near the filter inlet on the right, you can see one of three Least Kilifish and one of a dozen Eastern Grass Shrimp. A single brown leopard ramshorn snail, a handful of baby pond snails, and at least one Kilifish fry are there but hiding. Lots of microorganisms and copepods living among the copious leaf litter.

Current Flora: Mayaca fluviatilis (left), Didiplis diandra and an unknown Ludwigia sp. (back center), Juncus repens (right), Lobelia cardinalis (front right), Azolla caroliniana (floating)

I am really enjoying this tank and hopefully I will get a better picture to share here.

In the meantime:
