Thai betta fish should not be mixed with other tropical fish, because Thai betta fish are fierce in character, like to attack the same kind, and they are very aggressive, and the same sex often beats their heads. If they are mixed with other tropical fish, they will constantly attack other tropical fish, so it is best not to keep them together with other tropical fish.

If breeders want to improve the ornamental value, they can also choose to mix some tropical fish. However, in polyculture, we should pay attention to selecting some fish with faster swimming speed, so that they can flexibly avoid the attack of Thai betta fish and avoid injury. Also choose some gentle fish, which can reduce the situation of competing for territory. In addition, breeders should ensure that they have enough living space and food, which can also reduce the frequency of fighting.

If it is a female fish, try to raise two together. Because females are relatively mild in character, if they are raised together from infancy, they will be familiar with each other's existence, and the probability of conflict in adulthood is still relatively small.

If it is a male fish, it is not recommended to keep it together. Because the male fish's character is fierce and very aggressive. Especially between two male fish, there will be constant fights.
