So I'm having a bit of a weird problem over here...
I "rescued" a couple of female betta fish from wal-mart about a week ago, and they've been doing great. except for one thing... yesterday evening I discovered a bubble nest in Tifa's tank. And as far as I've read, only males do that.
So my red flag went up.
I'm under the suspicion that my little girl is actually a short finned male.
I should also note she is just as aggressive (if not more) than my male, Winston.
Also I searched and searched for "her" ovipositor and I see a small grey spot that MIGHT be it, but it looks nothing like my other female's.
I've read that in some cases there are domesticated males that develop shorter fins.
Are there any other ways I can tell the difference?
I need some experienced betta owners to help me out here!
Thanks so much!
