Check out Serpa design on YouTube, he has a lot of great micro builds.
I'd keep it simple and do no fish, just shrimp + snails + a couple crabs + live plants.
The fediverse needs a place for aquarists! Saltwater, freshwater, breeders, fishless aquascapes, ponds, puddles, and bathtubs. If it's full of water and you're proud of it, we'd love to see it.

I've tried a couple experiments with tiny aquariums in jars and bowls (0.5-1gal). The water parameters can be tricky to stabilize since the ecosystem is so small and any changes (like feeding food) can cause major swings. I would definitely advise plant heavy, and stick to small invertebrates like snails and shrimps and avoid fish.
I have an unused fishbowl lying around and your question sparked for me.
I'll have to look in to doing something like you so it doesn't just sit empty and collect dust.
Iirc, the problem with fishbowls is the small surface available for gas exchange. So I'd advise against fish in such setup, especially if you dont run a pump/airpump. Should be fine for invertebrates like shrimps, snails, crabs, but with heavy planting. Can't wait to see your finished project!
