The water level for breeding betta fish is usually around 10 centimeters. This is because in the breeding tank, if the water level is too high, it may be difficult for the betta fish to find a suitable breeding place, while if the water level is too low, it is not conducive to the formation and maintenance of bubble nests.
Preparation of the Breeding Tank and Other Precautions
Cleaning the Breeding Tank: Make sure the breeding tank is clean, and then put in aged clean water, water with Indian almond leaves, foam boards, etc.
Water Temperature Control: The water temperature should be kept between 26 and 28 degrees. Ensure that the water temperatures in the male fish tank and the female fish tank are the same or the male fish tank's temperature is slightly higher by one degree.
Lighting Conditions: A faint light at night is sufficient. Turning on the light is also okay, but it may consume more electricity.
Placing Indian Almond Leaves and Aquatic Plants: Indian almond leaves can provide a suitable environment, and aquatic plants are helpful for betta fish to hide and breed.
Observation and Adjustment: Observe whether the male fish is blowing bubbles the next day. If not, the male fish needs to be replaced. If the female fish actively runs under the bubble nest, it indicates that the breeding is successful.
By following the above steps and precautions, the success rate of betta fish breeding can be effectively improved.
