My most recent betta is a female from Petsmart. I was in there one day, poking around because I had half a tank to fill, and came across her. I was shocked. STUNNING marble female with bright aqua marbleing and red accents on the ends of her crowntail fins. At Petsmart!!! They had her sister there too (or so I assumed, similar coloring. Not quite as vibrant though) and one other red girl. All the males where boring. Blue. Red. Your typical store betta.
She has just as much personality as my males, and from the start was more friendly than Rory, her tankmate (they have a divided ten). She's tiny, though has grown a bit since her. Hoping to get some female guppies to add some more movement to the tank. Or something. At least she hides less than the males.
