depends on the specific species. If it is a Chinese betta, you can raise a male and a female. It can also be raised in groups, but the number of groups should be more than 10. Because if the number is large, it is not easy to fight. The character of Chinese fighting fish is relatively mild, as long as the two male fish are not put together alone, there will be no fighting in general.
If it's a Thai fighting fish, you can only keep one. Because of the irascible character of the Thai fighting fish, if two fighting fish are kept in a fish tank, they will fight until one of them dies, so the Thai fighting fish can only keep one. If breeders want them to breed, they can first put transparent partitions in the tank to allow the two fish to adapt to each other's presence, and when they reach estrus, they can remove the partitions and let them pair up on their own.
should be used to raise betta fish? It is better to use good tap water to raise betta fish, because tap water contains chlorine, which will affect their health, but chlorine will disappear after exposure to the sun, so it is better to use trapped water to raise betta fish. Douyu does not require high water quality, and the PH value should be controlled between 6.5 and 7.2. Although they do not require high oxygen, but if the oxygen is insufficient, it is easy to jump tank behavior, breeders need regular oxygen to ensure adequate oxygen in the water.
