Female betta fish are typically less ornate and decorated when compared to their male counterparts.Unlike male betta fish, female betta fish can live together comfortably in the same tank. When they live together, the cohort is called a 'sorority'. Generally, a good number to keep together is 4-6 female betta fish. They enjoy having their own personal space, meaning that they should have enough foliage to hide in when they want to be alone. Often, plants or aquarium decorations can serve as good hiding places for betta fish.
