Set up a separate breeding tank (5-10 gallons) with a sponge filter, heater, and a few hiding spots. Keep the water level around 6 inches and maintain a temperature of 78-82°F (25-28°C). Include a floating plant or a plastic cup to serve as a nest-building site.

2. Conditioning the Breeding Pair

Select a healthy breeding pair with desirable traits. Feed them a high-protein diet of live and frozen foods for 1-2 weeks to trigger breeding behaviors.

3. Introducing the Pair

Place the female in a clear container or breeder box inside the breeding tank, allowing the male to see her but preventing physical contact. Observe their behavior for a few days. If the male starts building a bubble nest and the female displays vertical stripes and a swollen belly, they are ready to breed.

4. Breeding

Release the female into the breeding tank, and observe the pair closely. The male may chase and nip at the female before embracing her in a mating ritual. During the embrace, the female releases eggs, which the male fertilizes. The male then collects the eggs and places them in the bubble nest.

5. Post-spawning Care

Remove the female from the tank immediately after spawning to prevent injury or stress. The male will continue to guard and tend to the bubble nest, ensuring the eggs are safe and oxygenated. Monitor the male’s behavior closely and remove him from the tank once the fry (baby fish) begin to hatch, typically within 24-48 hours after spawning.

6. Fry Care

Fry will initially feed on their yolk sacs and remain in the bubble nest for a few days. Once they start swimming freely, provide them with appropriately-sized, nutritious foods such as infusoria, newly-hatched brine shrimp, or microworms. Gradually transition to larger foods as the fry grow.

7. Raising Fry

Maintain pristine water conditions in the fry tank, performing daily partial water changes to remove waste and uneaten food. Ensure the water temperature remains stable, and use a sponge filter to prevent fry from being sucked into the filtration system.

8. Separating and Housing Fry

As the fry grow, you will need to separate them based on their size and aggression levels. By the time they reach 6-8 weeks of age, aggressive or territorial individuals should be isolated to prevent fights and injuries.

9. Finding Homes for the Offspring

When the fry have developed into juvenile betta fish, usually around 2-3 months of age, you can start finding new homes for them. Reach out to local fish stores, clubs, or online communities to sell or rehome your betta fish offspring responsibly.

Breeding betta fish can be challenging and time-consuming, but it can also be an incredibly rewarding experience for aquarists interested in witnessing the full life cycle of these captivating creatures.
