Just going to say that some young males also have egg spots, it's not exclusive to just females. I have never seen a female with fins that long, so I'm going to say that it's probably a male.
wow, everyone's SO concerned about its SEX! XD If people can decide their own sex why can't fish? I mean whats the harm unless you're trying to breed correct? ^_-*
Well Idk anything about betta yet but I thought I'd tell you that it was great of you rescuing that betta and that it's SUPER cute, and I can't wait for another picture post! =]
Good luck with getting better! *huggs and gives cookie* =]
wallywestisthebest333 - Sex matters because males can not be with other bettas, but females can be housed together. If someone were to add a male betta to a betta sorority it would be disastrous.
