Whether male and female Betta fish can live together depends on the species of Betta fish and the specific circumstances.
The Situation of Mixed Breeding of Different Species of Betta Fish
Chinese Betta Fish: Chinese Betta fish have a relatively gentle temperament. One male and one female can be kept together. However, to avoid fights, it is recommended to use a larger fish tank and provide enough shelters and hiding places.
Siamese Fighting Fish (Betta splendens): Siamese fighting fish are more aggressive. Even one male and one female will fight with each other in normal times. They are only suitable to be put together during the breeding period.
Specific Conditions and Precautions for Mixed Breeding
Water Quality and Temperature: The suitable water temperature for Betta fish is between 18 and 28 degrees Celsius. The water quality can be purified water, tap water (which needs to be left standing for more than two days), or mineral water. Change the water every 5 to 7 days, or change it as soon as you see that the water is dirty.
Feeding: Feed 5 to 10 pieces of special Betta fish feed every day. Don't overfeed, as Betta fish may ignore you after they are full.
Avoiding Fights: To avoid fights, you can use an acrylic board to separate the male and female fish during the pairing period, or provide enough shelters and hiding places.
Specific Cases and Effects of Mixed Breeding
Chinese Betta Fish: Although they can be mixed and bred, you still need to closely observe their interactions to prevent any aggressive behavior. Providing sufficient space and shelters can reduce the likelihood of fights.
Siamese Fighting Fish (Betta splendens): Even when they are put in the same tank during the breeding period, it is still recommended to keep them alone at ordinary times to reduce the risk of the female fish getting injured.
