Today i was cleaning tanks, and while cleaning the tank of the mother of my spawn i thought, with 4 of her daughters and sister-in-law living as a sorority, i would add her in to free up some space. She was in that tank once before when it was just her and the rasboras but it didn't work out. So i kept a watchful eye an watched the following go on for about an hour. No nipping, no chasing, just this long posing contest between these two. They ignored the other 4 girls.
