Breeding giant betta fish is not an easy process. Thorough preparation is essential before you begin. Here are some fundamental steps for breeding giant betta fish:

  • Select the Pair: Choose a healthy male and female betta with good health, attractive colors, and appropriate size. Avoid close bloodlines to prevent genetic issues.

  • Prepare the tank: Set up a 20 gallon breeding tank with a temperature of 78-82°F (26-28°C) and a pH of 6.5-7.5. Include a heater, gentle filter, and hiding spots like plants. Leave space at the top for a bubble nest.

  • Introduce betta fish: Place the male in the tank first to establish territory with a bubble nest. Then introduce the female, keeping them separated with a barrier for a day or two.

  • Mating: When signs of readiness appear, remove the barrier for the pair to mate. The male will chase, nudge, and embrace the female to encourage egg production. After mating, he'll collect and place the eggs in the bubble nest.

  • Post-mating: Move the female to a separate tank. Leave the male to care for the nest and fry. Avoid disturbing the water, provide light feeding for the male, and prevent overfeeding.

  • Fry care: After a few days, the eggs hatch into fry. The male cares for them in the bubble nest. When they become free-swimming, transfer the male to a new tank. Feed the fry suitable food and perform daily water changes for optimal water quality. Please note that Giant Betta Fish take longer to grow than regular betta fish (up to 5 months to reach adult size).

Taking care of giant betta fish requires attention to detail and dedication. Here are some tips to help you care for your giant betta fish

Tank set up

Giant betta fish require a larger aquarium compared to regular bettas. A single giant betta needs a minimum of 10 gallons of water to thrive comfortably. The tank should be adorned with plenty of aquatic plants and rocks to create hiding spots and decoration for the fish. Maintain the water temperature in the tank between 76 to 82°F (24 to 28°C) and the pH level between 6.5 to 7.5. Regular water changes are necessary to maintain good water quality.


Giant bettas belong to the anabantoids family, which means they can obtain oxygen from the air through a specialized organ called the labyrinth. As a result, they don't require a powerful filter to maintain dissolved oxygen in the water. However, a filter is still essential to remove waste and reduce nitrate levels. Opt for a filter with gentle water flow to avoid stressing the fish. You can use options like hang-on filters, sponge filters, or aquatic plant-based filtration.


Giant bettas are tropical fish, so they need to be kept in warm water. If the tank temperature is too low or too high, they can become stressed or susceptible to diseases. Use a heater to maintain the tank temperature between 76 to 82°F (24 to 28°C). Additionally, use a thermometer to regularly monitor and adjust the heater as needed.

Food and diet

Bloodworms - Best Food for Giant Betta

Giant bettas are omnivorous, meaning they can consume a variety of foods. However, they tend to lean towards animal-based foods, so provide them with high-protein options. You can feed them dry foods like pellets, flakes, or granules, but also include live or frozen foods such blood worms or artemia. Avoid overfeeding to prevent obesity or digestive issues. Supplement their diet with vitamins and minerals to enhance their immunity and appearance.
