On the whole, the girls are doing very well. The two most aggressive girls are Sweetheart, the double-tail and Sapphire, the crown-tail. They don't stalk like Trouble did, but the have occasional bursts of chasing. Mostly after my beautiful copper girl, Pretty Bird. She is the only one that is ever stress-stripped. I don't see any nipped fins anymore, now that Trouble is out.
Sould I let them continue to work it out for awhile longer? If I have to take anyone else out, I would like it to be Pretty Bird, because the others are pretty well balanced when it comes to aggression.
Sweetheart is definitely the alpha and my favorite.
And I can't go without saying how sorry I was to read that you lost three of your girls to fighting. How devastating that must have been.
