I was wondering what kind of luck people have had with introducing new female bettas to already established sororities.
I've had a 10 gal sorority up and running since before Christmas, with 6 females who got along quite well aside from the initial territory spats. Last week, I noticed one of my females, Valentina, missing. I checked the whole tank but couldn't find her anywhere, so I guess she must have jumped out somehow and my cat got to her.. :( The hole near the filter has since been covered..
But anyway, my question is..Since there is now an uneven number of females, should I try buying a new female and introducing her? They don't seem to be fighting at all despite Valentina's absence, but I am also worried that if I get a new female, they'll gang up on her and be like "Ew, new girl!" XD
