I don't really know. Make sure she stays away from the other girls, but I don't know what else to do. To anyone reading this, I'm getting my first betta tomorrow. I have received lots of info from bryanacute, but I would appreciate any more helpful hints!
So what size tank are you keeping all these female bettas in?
Isn't this the second time you've had a female betta with fin damage like this from tormenting?
Do you have any photos of what this sorority tank looks like? I'm curious how you decorated it.
With my sorority, I provided easily over 30 plants, in addition to caves with other hiding spots, but regardless it didn't seem to make much of a difference. Every week I would continue to find them sustaining more & more damage.
Also my f-bettas are very healthy, active, but extremely aggressive, but even after all the epic battles they've had with each other none have sustained tail damage like the one you just posted.
That betta also looks quite small. I would guess it's probably about 1" at the most.
They are in a five gallon. I can't post pics now as there are relatives at the house. Her tank ( Cambodian) is in my room. I have a large castle and about 4 plants and a few cubby holes where one female can get in and only one.
They can get trapped when being chased with decorations that have only one opening. Most people recommend that any caves have more than one exit and entrance area.. My sorority won't have any caves for that reason unless I can find one that has many holes in it that are big enough. IMO that is not easy to find. Also a sorority should be at least ten gallons.
Oh wow....thats quite some damage, probably some of the worst I've ever seen.
....And I can definitely see you're problem. A 5 gallon is WAY too small to keep a Sorority. No wonder your girl has been so beat and torn up....there isn't nearly enough room in there for the girls to get away from each other, and it doesn't sound like the tank has enough plants or decorations either. Without enough space AND enough cover for the girls to get away from each other and break up the line of sight, you are going to have some serious issues, like you've already experienced, with possibly deadly outcomes.
Sororities are risky, and even in a perfect proper setup things can easily and often go wrong....these ARE an aggressive species after all, they were originally bred to fight. Yes, even the females.......and an improperly setup Sorority is just bound to crash and burn, leaving one with injured and dead/dying fish.
Its really a tricky and expensive business.....not a task for the beginner keeper to take on.
For now, please, separate your girls right away....you're only going to end up with more fish like this girl if you don't. If you don't have enough spare tanks, you can scoop the girls out in their cups/other small container and float them in he tank to keep them warm for a couple of days, just preform daily 100% water changes on their containers.
From there, unless you can acquire a 10+ gallon setup with a LOT of decor and plants(live or silk or both)(ideally, you want your Sorority tank to look like an underwater tropical rainforest....practically every inch of the tank occupied by something)within the next week or so, I would suggest just housing them separately for now. Depending on how many girls you have you may need to pick up a couple of new tanks(Kritter/pet keepers, Mideium-Large size make excellent cheap setups in a pinch)and heaters, but you can house two of the females in the 5 WITH, and only with, a divider in between.
Once you have that all sorted out, you can start doing a but of research on Sororities if you're still interested in keeping one in the future....there is a TON of amazing info here on the forum, and a great Sticky you should definitely read though. With the girls separated, you have some time to research, save up, and set up a good proper Sorority later on if that is your eventual goal. ;)
