Obviously suffering from a lack of Beta understanding here - as the only advice my LFS gave me when considering Beta's was 1 x male and no more than 3 females in my 70G community tank. Flaring, yes by all 4, the male has his favourite and tolerates her anytime but the others simply puff up at each other for 3 seconds and move slowly on but usually they tolerate each other with no flaring - I have noticed however that the females colours drain rapidly from them and come back again just as quick - why is this???
