It is a great situation to have more females than males for GB rams, particularly in a tank that is mainly for show. That way the male does not focus on one female who might not be ready to spawn.
It is also a good situation if you want to get a spawn, but the size of the tank can play a role. If the tank is too small, the extra females can interfere with the pair that is spawning. But if the tank is around a 20-long, there is plenty of room and the extra females then are more like dithers. Dithers can make the spawning pair better parents because they need to protect the eggs and fry. But remember to keep a light on or night light on at night so the parents can continue to protect their spawn.
