Amanda, Pennywort is ideal. Just let it float, in a couple days the leaves will face up and the roots will start to grow dangling. I have it in a couple tanks, had it in this 10g too but it got too tangled and I wanted to float the swords as an experiment. Some floating pennywort will make a world of difference to the betta and your view.
Inga, that is one "problem" with this tank, the lack of a light. It is in front of the window, and its difficult to see the fish. Those bright blood-red Boraras are pale shadows. But it is an experiment in low-tech, and aside from the viewing issue it is certainly thriving.
This is about the only tank I can raise pond/bladder snails in (still not sure which these are, they are quite attractive when they mature). I have Malaysian livebearing snails in all the tanks, they tolerate soft water well. Pond/bladder do not, they need calcium and my water is near zero calcium. But this tank is around pH 6.6 which is higher than the others and they have done well. I move them to the 115g now and then, some manage to survive in there, it has dolomite in the filter to buffer the GH at 2 so that's probably why. They don't seem to reproduce in that tank though.
