For instance, the fish ranked at the end showed higher levels of mutual shows, compared to the fish who were of lower ranks. The researchers also found that the period of the shows differed depending on whether an attack occurred. The consequences of this research imply that female Siamese combating fish warrant as much scientific study as males, as they seem to have variations of their behaviours besides. There has been much analysis in the courtship behaviour between male and female Siamese combating fish. Studies commonly focus on the competitive behaviours of males in the course of the courtship manner. For instance, one study found that after male fish are in the bubble nest phase, their aggression toward ladies is kind of low.
