Ive always had betta fish but this time was the first time i bought a female so i thought. Ive tried mating my beta and i followed everything her horizontal black stripes changed to vertical white stripes, but nothing happened, by the way she is a lite blue with a gray belly. now after numerous attempts of trying i stopped until one day i look in her bowl she's dark blue with red stripes and now flares up at the male, and I've had them for a month now and this just happened two days ago. Then yesterday she goes back to the light blue gray belly beta she was when i bought her, and i don't have the slightest clue whether the betta is girl/boy. what do you think?
