My LFS has scarlet badis. Very pretty little guys. Extremely small. They seem to have betta-like personalities. Prowling about, giving you the stink-eye kind of thing..
I opted for celestial pearl danios for my planted 10. I've got 8 of them, along with a lone pair of old silver hatchets. You don't see much of the CPDs because they're constantly darting in/around the more densely planted areas.
