A silly question, but I’m a newbie. Is there any way that we can differentiate between a male and a female betta? Thanks!

Female bettas have short dorsal, anal, and caudal fins and they are not brightly colored, whereas male bettas have a rather long dorsal, anal, and caudal fins and are very brightly colored.
