2 white spots?? none of my girls have more than 1, and to repeat what has been said many times before, the ovipositer is NOT a sign of a female. i had a male DTPK who was sold to me as female. i discovered she was actually a he, when he spawned with a CT female in the sorority tank. and he had a very clear white sticking out "ovipositer"they are all females,all got the two white spots underneath
will wait for the pics but it does just sound like this betta is eggy, some females get enormous with eggsits just mega fat round the stomach area compared to other two, scales arent raised,not overfeeding.its got me baffled,will try and post a pic but not promising.
