The Female Koi Betta is a stunning selectively bred variety of Betta splendens, prized for its vibrant koi-style colouration. These beautiful fish typically display a combination of red, orange, white, yellow, and black markings, with each individual developing its own unique pattern.
Female Koi Bettas generally have shorter fins than their long-finned male counterparts, giving them a compact and active appearance. Their striking colour patterns make them an excellent feature fish for planted aquariums and carefully selected community setups.
Koi Bettas are labyrinth fish, meaning they can breathe atmospheric air directly from the surface. They appreciate aquariums with gentle filtration, planted areas, hiding places, and easy access to the water surface.
Female Bettas can be territorial, particularly towards other female Bettas, so careful consideration should be given to tank mates and stocking. They are best kept individually unless an appropriately planned female group is being maintained by an experienced aquarist.
A varied diet of quality Betta pellets supplemented with frozen or live foods such as bloodworms, daphnia, and baby brine shrimp will help maintain excellent colouration, health, and condition.
With their incredible koi patterns, compact fins, and individual personalities, Female Koi Bettas make a fantastic centrepiece fish for a planted freshwater aquarium.

Female Bettas can be territorial and may become aggressive towards other Bettas. Individual temperament varies, so they should be introduced to community setups carefully.
Yes. They can potentially live with peaceful, appropriately sized community fish such as Corydoras, small Rasboras, Ember Tetras, and Otocinclus. Avoid fin-nipping or aggressive species.
It is possible in carefully planned groups known as sororities, but it is not suitable for every fish or aquarist. Territorial disputes can occur, so individual housing is generally the simpler and safer option.
They are carnivorous and thrive on quality Betta pellets supplemented with frozen or live foods such as bloodworms, daphnia, and baby brine shrimp.
Yes. Gentle filtration helps maintain water quality, but avoid strong currents as Bettas are not strong swimmers and prefer relatively calm water.
Using strong filtration
Powerful currents can stress Bettas and make swimming difficult. Use gentle filtration with minimal flow.
Keeping them with fin-nipping fish
Avoid species known to nip fins or harass slow-moving fish.
Keeping multiple females without planning
Female Bettas can establish territories and fight. A single female is often the easiest option for a peaceful aquarium.
Overfeeding
Bettas have small stomachs. Feed small portions and remove uneaten food to maintain water quality.
Not providing cover
Live plants, floating plants, driftwood, and caves provide security and allow the Betta to rest and explore.
