Boy bettas have really big fins and are very colorful, and girl bettas are pretty much the opposite!
bettas are very territorial fish, the males fight for their territiory.
With bettas, the males have longer fins, even the plakat (short finned) type.
This is a BIG NO NO!! Bettas need at least 2.5 gallons of water to themselves, and if you put a male and a female together, it will most likely result with you have two dead bettas. Keep your boy and girl in separate 2.5 gallon heated tanks.
it is both it is better for a boy and a girl

i dont agree in both .but the better one is a girl to girl relationship
