Telling a Betta's Gender
Typically, you can tell the gender of a betta by the age of 3 months. (go here to determine your betta's age: http://www.bettatalk.com/fry_growth.htm )
Every betta is different and it is not always fin length that determines gender. There are some short-finned males and some long-finned females.
Male bettas typically...
-Have longer fins than females. (unless they are short-finned or plakat tail type)
-Have thicker ventrals than females.
-Have a beard when flaring (you can test this by putting a mirror up to your betta's tank)
