This is going to seem weird, but a while ago I had to separate platies by gender after the breeder I purchased from messed up and gave me males instead (said males are comfortably living along a betta now, thanks to the advice of someone here). The thing is, the platy most of the males seemed to chase has begun exhibiting mating behavior towards other females. I know males will do that without females around, but her? She keeps wiggling herself in front of every fish her size and I'm getting kind of scared. I've heard some livebearers will change genders when there are no males present, but can't find any conclusive evidence on the matter. Should I just... let her be? I feel like I've taken away her happiness. She chases after guppies, too, but that shouldn't be an issue, right? The other platies swim away from her the way they would from males, and yes, I've made sure it's a female multiple times. Probably pregnant, too.
