I have Zebra Danios in a 29g tank, and I call them my "sharks". Mine are savage lol I personally wouldn't put them with a Betta, as they are top feeders and are territorial to their space. Seeing as Bettas need the top for air, there's a clash in interest. A peaceful mid dweller would work better, or a bottom dweller. Danios are very active fish, which may stress out the Betta. Anyways, I would personally go for another type if it were me, since I see how they can be in a community setting.
Harlequin Rasboras, Glowlight Tetras, Celestial Pearl Danios are a few I've owned that would do well. Most fish need 5-6 in a group, so that's why 10g is a small tank for communities. I have heard of people using Platys as well.
