– Least killifish
– Medaka rice fish
– Micro rasboras (Like chilis or phoenix)
– Various small killifish species
– Sparkling gourami
– Ember tetras
– Badis
– Aquatic insects
There are a good variety of nano fish that could live in this tank. Everyone always suggests bettas like they’re the only option.
You could put a betta in there if you have tall plants or similar places for it to rest near the surface. I have a tall tank also, but with a betta leaf bed or floating log they’ll do fine

I would say a Betta would be pretty good for an 8g. That’s enough space for them, and with enough plants, it would be a pretty happy camper
