Any chance for more pictures, Annie? I kept the lights off of my sorority tank for about a week after adding the ladies and that seemed to help. My smallest one got picked on but her fins are now regrowing and didn't need to be medicated. Provide tons of tall plants that break up the line of sight along with some nice low laying places to sleep and rest, seems to help also. I agree with Gina, there will always be an alpha female but provide lots of safe places.
