Those poor girls, I'm so glad that you got to save atleast a couple!!! It might be best to keep them seperate for now, as sororities are alot of work, and you need at least four females to have a proper sorority. If you wanted to have four together, you would need atleast a ten gallon tank, and you would have to watch them closely to make sure that they don't fight too much for the first few days. Since you just have the two, keep them seperate and just care for them like you would a male betta =) we would love to see pictures, females are sooo cute!!!!!
My Current bettas:
Sullivan- Orange rose tail halfmoon male
Daisy- Mustard Gas (black and yellow) veil tail female
Milton- Teal butterfly halfmoon male (mom's betta)
DFTBA to nerdfighters working to decrease world suck!
