The Verdict: You all were right, so far... lol
The girls are all in together still. The two bigger girls once again tried to boss around the others. The first one of the two pics I had posted is definitely the more aggressive. She's been after everyone and sadly it shows on her tail fin

The other large female got a rip down her tail fin, if it went a bit farther she'd look like a DT, but otherwise she is ok too.
I'm going to give these girls salt baths later to make sure nothing more happens to the fins.
The first one, when I attempted to sleep last night was going at it with one of the average sized girls, my blue one, Salvia. Salvia refused to back down and would chase her down lol There were a few times they would grab each others mouth/face and just hold on until one needed air. I don't know if that's good or bad? I broke it up the first two times I saw it, but the third I just supervised it, and neither seemed to get hurt. Here's a pic I snapped of it, if this happens in the future should I let them do it or seperate them?

And here are the two big females the morning after...
And THANK YOU for all the help so far!
