As long as you have lots of plants it works out well! Its when you give up on the sorority that it falls apart. Here's a pic of mine as well for reference:
I have a 33 gallon here with 7 girls at the moment, one in quarantine to soon make 8 :D hoping to find a Black CT with red finnage to finish off and make it 9.
They've all been in there since Wednesday and not one fight has broken out, there is still a possibility but I monitored my girls before they went in to make sure that they were sorority quality. Sometimes on the rare occasion you'll have to take a girl out if she's being too much of a bully and hurting the others, but that's a rare occasion.
Some of the girls today (had to take the massive water sprite out for a bit)
