Was not sure of its gender since I first got this plakat betta a few months back. As it grew, I felt that it was most likely female. But recently, it started making quite a few bubble nests and I am confused all over again. Also, I can't see any obvious egg spot/ovipositor tube. The ventral fins...

i've had this one in a quarantine for a bit now and i know it doesn't have any illnesses, but i can't quite tell if it's female or male now my lfs said it was a female plakat
