Gonna try to keep a "shoal". Got a 32" cube so roughly 140g. Not that they need a ton of swimming space. But from those w experience. What number is good. 5? 7?
 
They may not need a lot of swimming space, but they still contribute bioload and they can get pretty big considering their shape and girth.

That having been said, I second Small - to me odd numbered groups always look nicer to me, more "real" for some reason.
