Good list. Nano tanks are very cool and they present some very unique challenges. I would say that nano-tanks are probably not for beginners, but they seem to be recommended to them the most often.
Er, in a divided tank? Or can you actually keep a male and female together (I'm guessing you don't mean MM pairs) in a 10G? I never did much research, but I thought you'd only put a pair in a tank long enough for them to breed, and then divide them again. If you meant females though, a trio would make perfect sense, yeah.Good list. Actually, all betta species can fit in a 10g in pairs or trios.
I doubt this would work with betta splendens, but there are numerous species of bettas that do not share the siamese fighting fish's pugnacious nature. Betta albimarginata would probably be a bit cramped in a 10 but the coccinea group would do just fine.Er, in a divided tank?

I'm going to admit to being a little curious about this.
