I have a 48" long 60 gallon tank that is primarily filled with male Peacocks. There are about 12 fish all together and it is overall a very peaceful tank. I'm upgrading to a standard 125 gallon and I'd like to add a few fish to the mix. I know they are generally better in groups, but has anyone had any luck with a single Frontosa in a Peacock tank? That's the route I'd prefer to go, but if instead I added a group of 4 would female Frontosas likely cause aggression amongst the male Peacocks?... I do have a large female Parrot Fish in the tank now and it's not a problem (she's the boss).
