Caring for female Koi Betta fish requires attention to detail, particularly regarding their habitat, tank conditions, and overall setup to ensure a healthy and vibrant life.

Habitat, Tank Condition & Setup

Creating the perfect habitat for your female Koi Betta fish involves setting up a tank that mimics their natural environment as closely as possible.

Tank Size

A spacious tank is crucial for the well-being of your female Koi Betta fish. A minimum of 5 gallons per fish is recommended. For a sorority of female Bettas, a 20-gallon tank or larger is ideal. This provides ample space for each fish to establish its territory, reducing the likelihood of aggression.

Water Temperature

Maintaining the correct water temperature is essential for your Bettas' health. Female Koi Betta fish thrive in water temperatures between 76-82°F (24-28°C). Use a reliable aquarium heater to keep the temperature stable, as fluctuations can cause stress and health issues.

pH Level and Water Hardness

The ideal pH level for female Koi Betta fish is between 6.5 and 7.5. Water hardness should be kept at a moderate level. Regularly test the water to ensure these parameters remain consistent, and make adjustments as needed using pH stabilizers or water conditioners.


A gentle filtration system is crucial for maintaining water quality without creating strong currents that can stress your fish. A sponge filter or a filter with an adjustable flow rate is ideal. Regularly clean and maintain the filter to prevent build-up of harmful toxins.


Choose a soft substrate to prevent damage to the delicate fins of your female Koi Betta fish. Sand or fine gravel works well. Avoid sharp or rough substrates that could cause injuries.

Decor and Hiding Spots

Providing plenty of hiding spots and decor in the tank is essential for reducing stress and allowing your Bettas to establish their own territories. Use a variety of decorations such as caves, driftwood, and especially live or silk plants. Live plants like Java fern, Anubias, and floating plants like Amazon frogbit or water lettuce offer excellent cover and contribute to a natural environment.


Moderate lighting is recommended for female Koi Betta fish. Avoid intense, bright lighting which can stress the fish. LED lights with adjustable settings are ideal, allowing you to create a gentle day-night cycle.

Water Changes

Regular water changes are vital for maintaining a healthy environment. Change 20-25% of the water weekly to keep ammonia, nitrite, and nitrate levels in check. Use a water conditioner to treat tap water before adding it to the tank to remove chlorine and other harmful chemicals.

Tannin-Rich Water

Creating tannin-rich water, also known as blackwater, can benefit your female Koi Betta fish by reducing stress and mimicking their natural habitat. Adding Indian almond leaves or driftwood can release tannins into the water, providing a soothing and health-boosting environment.

Tips to Create a Female Koi Betta Sorority

Creating a successful female Koi Betta sorority requires careful planning and attention to detail to ensure the health and harmony of your fish.

Sisterhood: Born and Raised Together

When forming a sorority, it's best to choose female Bettas that have been born and raised together. This familiarity can reduce aggression and help establish a peaceful hierarchy within the tank.

Tannin Water

Female Betta fish thrive in tannin-rich water, which mimics their natural habitat. Tannins can help reduce stress, prevent diseases, and enhance the coloration and scale development of your fish.

Provide Hiding Spots with Real Aquatic Plants

Creating a natural environment with plenty of hiding spots is crucial. Use real aquatic plants and floating plants to provide cover and reduce stress among the fish. This setup not only makes the tank more attractive but also gives the Bettas places to retreat and establish territories.

Lifespan of Female Koi Betta Fish

What to Feed Female Koi Betta Fish

For optimal health, female Koi Betta fish should be fed a diet of high-quality Betta pellets supplemented with live or frozen bloodworms and brine shrimp.
