Few Asian nations prefer breeding of this fish due to their ferocious and intense nature. Male Betta fish flash their colorful fins and gills, in the event that they purchase the feeling of threat to their territorial nests. Aggression and hostility expands with adulthood. Similarly, the length and weight of their tails and fins are also enlarged. Suppose a male Betta comes across another male Betta, they’ll behave as if they are the biggest. If this effort does not create panic in other fish, they will float beside other Betta males, thrashing the water.
