Bettas need exactly the same tank conditions as any other tropical fish. Clean water, a filtered, heated tank, decent food. They are no different from any other tropical fish. Would you put a kissing Gourami in a 10 gallon un-filtered tank?I mean, if it's for a betta, they don't need extra oxygenation at all since their labyrinth organ lets them breathe air. And if a betta is all that's going to be in a 10g, you probably wouldn't even need a filter as long as you do the weekly water changes like you should.
Though, regardless of all that, plants certainly never hurt to have. If you don't want to go through the bother of lights and ferts and what have you, growing a pothos cutting or two out of the water's a great idea. Looks very pretty, sucks out what little pollutants one fish will produce, eventually grows a thick bundle of roots for your fish to play in.
That's... what. I didn't say any of that at all?
The only point I was making is that Bettas need the exact same conditions any other tropical fish needs. A labyrinth organ doesn't make a betta able to tolerate permanent low oxygen conditions in a tank any better than any other tropical fish. Bettas and Gouramis are very similar other than appearance and size. They are from the same order of fish (anabantiforms). So I wonder why no one ever suggests putting even small Gouramis in tiny unfiltered tanks with uncertain oxygenation? They are labyrinth fish too.The only point I was making was that oxygenation is a non-issue for a fish that can breathe air.
