So the original 3 were removed and I rearranged my entire tank. I purchased 4 more girls, slowly replaced their water with the tank water and floated them all in the tank for 1hr just to avoid any stress with temp change.
I released them one after the other and WOW... I thought Isobel was aggressive?!?! One of the newbies was down right insane! She would swim underneath the other girls and push them up, non stopped flared, chased, bit, etc... She actively pursued them all, including Isobel. Isobel and her went round at round, taking turns taking nips.. it was extremely uncomfortable to watch. I removed the aggressive newbie after only 5 minutes. She flares at even the site of my fingers when I try to feed her! I'm strangely attached to her but avoided giving her a name as hubby won't let me keep her (would involve buying/putting together another set-up.) Le sigh...
Isobel has also been removed as she would not stop biting, either. Both the aggressors will be returned and until them will stay in their cups.
So I'm left with a Sorority of 5. Sparkle and It Zwibble, my originals, Isobel (#2, but my 2 year old doesn't realize), Flower and Baby (who I just call Little Red). They are all getting a long quite well. There is an occasional flare and a chase but no thrashing of tails or nipping. I think they are too busy exploring their new digs. It's really cute to see them hanging out in the different spots I made for them or resting in plants.
I have to admit that I have gotten up several times during the night to "count," but I realize that I'm probably stressing them out by turning the tank light on and off.
Do you ever feel at ease with a sorority?
