Why not stock the 20 gallon with what you want and leave the betta in his tank?
I’ve never heard of a betta as a centerpiece fish. They CAN be in community tanks, but keep in mind that they don’t do as well long term for a couple of reasons. First, if you have the flow you need in a community tank it will be a bit much for a betta. Second, the busyness of a glow light tetra tank would be stressful for a betta, and third, bettas simply do so much better alone in a calm, tranquil, small environment. Speaking from experience, I can say that the bettas I’ve had in large community tanks don’t do as well.
