aggressive female bettas
Actually, I'm having a female betta pecking order problem, myself. I'm rommel39's girlfriend, and all our other female bettas (I think we've had 6 so far, usually in combos of 3) have always got along fine, with the occasional guarding of certain hiding places.
But tonight I got three female bettas to add to my newly set up (and cycled) 55 gallon tank, and as soon as the three were set loose they went for each other. At first one wandered off and two fought, but after I seperated one, the other two went at it. This was beyond the small-scale gill flaring I've seen before. This was full-fledged betta dance of death.
The only thing that seemed different between these females and the ones rommel39 and I have bought in the past are that these three were seperated into cups at the pet store, whereas our old LFS sold them together in a tank.
For the moment I've got two each separated into clear plastic cups floating in the corners of the tank (anchored to the sides, not floating around). The third has reign of the whole tank. There is still gill flaring if the free one gets near the cups.
What should I do!?!
If I slowly introduce each betta to the tank, will they chill out with each other and find a power structure?
Should I get betta boxes for them?
Or should I try to return them to the store, saying that they are just too aggressive?
Oh, although my five diamond tetras were terrified of the drama of the dueling bettas (they disappeared for about 2 hours), the one betta in the tank has not even taken notice of them - so there does not seem to be aggression to other fish. (My 8 inch pleco was, as usual, oblivious.)
Any advice? Thanks.
