Haha you should see Genghis. She is my female ct from my last spawn and she flared more than the male! She is a bit of a dragon...

Put him/her in a bag of wqater then place the bag into a male bettas tank, if they flare its a male if not, female
Also put the bag in front of a mirror or put a mirror in his tank. If it flares male, if not, female.
my girls flare...they are feisty madams!
