Not all Siamese fighting fish respond negatively to other males, particularly if the tank is large enough for every fish to create their very own targeted territory. In normal, experiences have shown that females display similar aggressive behaviours to males, albeit less commonly and intensely. An observational study examined a collection of female Siamese fighting fish over a period of two weeks, during which time they were recorded attacking, flaring, and biting food. This indicated that after women are housed in small groups, they form a stable dominance order, or “pecking order”. For instance, the fish ranked at the end showed higher levels of mutual displays, in comparison to the fish who were of lower ranks. The researchers also found that the length of the displays differed depending on no matter if an attack happened.
