Best rainbowfish for community tank school?

All Rainbows exhibit pretty similar behavior. They are all active and peaceful. I can't think of a reason that would make one better than others for a community tank.

The big difference is color.

Here are some from my tank. I like mixing them so that the colors are like a "rainbow" moving around the tank.

Boesemani Rainbow (Melanotaenia Boesemani)
