It can take quite some time to pair up, and once they do, they may kill the other pair. I have 5 GBR's 1 male and 4 females in a 75gal tank. He paired up with one female, and chased the other 3 to the other side of the tank. as long as they stay away from the pair, they are fine. Once the eggs are laid, the male usually cases his mate away as well, and guards the nest. The females rarely fight with eachother, usually only during feeding, then its more of a chase not a fight. Keep an eye on them fi you see one stuck in a corner of the tank for long periods of time, then that one needs to be removed or it will be killed. I think part of the reason for my success has been the ratio and number of fish 1 to 4 so that no one fish seems to get all the abuse, plus they have plenty of room and lots of places to hide. Good luck, I love my GBR's they each seem to have their own unique personality.
