My tank is up and running! It's a 10 gallon with a male Betta and three Albino Cory Cats.
I just got my Betta today, his name is Fluka! He gets along great with the Cory Cats. Sometimes the frantically swimming Cory Cats bump into him, but he seems to just ignore it. He never flares at his reflection. Fluka started eating right away, and it looks like he's already started to work on a bubble nest! I couldn't have asked for a better Betta!
