I dont know... sororities are just too risky and many people quickly jump the bandwagon to do one. I mean, I remember reading a members post where he/she had a sorority for months and then one day BAM! dead fish.
I think the SAFEST way to do a sorority is if all the females are sisters who have been raised together from birth.
I still think people are quite quickly jumping into "sororities" because its the "in thing". I don't think I would ever do an all female betta tank. Maybe 4-5 (sibling) females in a massive community tank one day, but not stuff eight females from petco cups into a 10 gal (I know the OP's tank is bigger, just using examples I hear). I KNOW other members here have lost females because of fights that have taken place in the sororities. Why risk it?
My 10 gal tank has only one female betta and some other peaceful community fish. I like it this way, she gets to be the centerpiece and I dont risk her beautiful fins and inflict stress on her.
Quote from OFL, an experienced member of the board:
Enough with my anti-sorority rant lol... It's my opinion
on the subject. Everyone's free to have their own.
That was OFL's reply to my thread. In my experience sororities are stressful on the fish, and like mine did, get sick and possibly die. Sororities should be in 20 gallon minimum and the females should be related.
Well, I am convinced all of you are right. There is a reason these fish languish in tiny cups and jars their entire lives - they obviously like it that way. I will never again feel sorry for them. They almost don't deserve
Today one fish, a pearl with red fins, was chewed up pretty good and almost every one had minor fin damage. The colors are not great in any of them either. And yet, the bickering and bullying continues. These are 7 females in a 33 gallon community tank (same as a 55 but not as tall) with mostly Tetras and Glo-fish. There are plenty of plants and other places for them to hide and find comfort and solitude, but no, they choose
to seek each other out and be miserable instead.
Bettas are not for me. These are going back into the tiny cups where they belong. They will be nursed back to full health as quickly as possible and then returned to the store. I will simply "donate" them back and consider this an education.
These fish simply hate each other on a level we humans can't comprehend. I wouldn't risk trying it again even with a pair of newborn female conjoined-at-the-head identical twins in an olympic-sized swimming pool.
