Boes are good. I would keep them in a ratio of 1M: 2-3F, and you could get 3+ of them 2M:4-5F is good, then you get to see the males show off toward each other. They are generally fairly social, not too argumentative. They compete mostly by coloring up and showing each other the colored band on their head, in front of their dorsal fin.
If you buy them young they will not be very colorful, and it might be difficult to tell M from F for a while.
