Got this little girl from petsmart she was just labeled female betta, which I'm guessing is just plain veiltail females with her fins were all clenched together,(I got her for 99 cents) when I brought her home and put her in her new 2.5 gallon tank her fins spread right up. She looks like a blue and red HM but I can't really get a good picture of her flaring to show off her full spreaded fin
she is a VT. petco only sells HM males, unless you're lucky enough to get a HM female as a "baby betta." most corporate pet stores seem to sell a wide variety of males, but only CT and VT females. their suppliers probably either keep the females of other tail types for breeding or online sales since in the mainstream pet trade, males sell WAY more easily than females. if the supplier has the choice of selling a HM female for a buck or two to be resold by petco, or sell her online for $5-10, which do you think he's gonna choose?
Rays are tiny bones that allow the tail to spread. And you can not judge the type of females solely by their shape. And MoonShadow is wrong, she clearly has two rays. Believe me, I own a four ray female and it is way more obvious. She may be a PK, which would have two rays as well.
