Ok. I got two "female" betta's about three days ago. Long story short, I was very misinformed, and told that two females could be housed together. Despite my research I decided to listen to the sales woman. Big, stupid mistake. I have two, a pink and a blue. The pink betta was flaring and chased the blue betta around a lot. Then they seemed to chill out. But the flaring and chasing started up again. I've now separated them into separate bowl. They were together for about two days, one night, before I separated them.
I posted pictures of them in the general betta chat, and have now been informed the pink female may actually be male. The pink betta did have a ovidepositer, or what appeared to be one, so i was confident it was female. Then I found out developing males may show signs of them. The pink betta is larger and has bigger fins than the female.
The pink betta has not tried to build a bubble nest as of yet.
Is there any chance they could have mated in the two days they were together? I am very worried, as there is no way I would be able to handle a "pregnant" fish.
