I never had any luck for long
I have tried sororities 3 times all in heavily planted tanks. They start out fine and then some months down the road something changes. They grow up? Someone looks or acts different and the whole thing falls apart. Someone or other dies, and I end up having to find separate tanks for everyone left. It seems like as long as everything stays perfect with their initial setup, they keep their territories, everyone plays nice together. But the minute there is the slightest change the fighting starts. I won't do it again. They are so pretty together and it is great while it lasts, but it doesn't last long enough to make it worth it. If you decide to do it, be sure you have enough space to house everyone separately if necessary. It is no fun at 9 at night when you come home to a dead fish and ripped fins and no place to put them.
