About Female Bettas Domestic Betta splendens are a fish that comes in a variety of colors and patterns, rather than a specific color. This is due to extensive selection of ornamental colors beginning in the 1900s. Female bettas tend to remain smaller than male bettas, along with shorter finnage. Females tend to be kept singly, or in a community tank with multiple females, called a "sorority". Sororities require careful planning to ensure that your female bettas remain stress-free and thrive within the aquarium. Husbandry & Care Temperament: Peaceful to Semi-Aggressive. Domestic bettas can vary in aggression on an individual basis. Minimum Tank Size: 5 Gallons for a single betta; 20 gallons for a sorority of 5+ individuals with a densely planted aquarium.
