Social hierarchies in sex-changing fish determine which will change sex, yet the complexities of hierarchy formation at neurobehavioural level are still being unravelled. Here, we investigate social within groups New Zealand spotty wrasse, integrating behavioural observations with neural activation patterns upon disruption. We find that dominance form linearly based on size, larger displaying more dominant behaviours and smaller submissive behaviours. Disruption induced rapid changes, particularly second-ranked fish, highlighting opportunistically adopt a position. Analysis reveals decision-making network is deeply involved establishment dominance, attaining showing significant differences to all other ranked fish. Overall, this study underscores complexity relationships their underpinnings providing foundation for further research into cellular molecular mechanisms socially controlled sex change, demonstrates disruption triggers changes both behaviour regions brain.

Abstract Innate social behaviors like aggression are modulated by sex steroid hormones such as androgens and estrogens. However, we know little about how the same hormone regulates similar in both sexes. We investigated role of androgenic signaling regulation Astatotilapia burtoni , a fish which males females perform aggressive behaviors. used ARα knockout (KO) animals for this study, was recently shown to be required male-typical mating. Surprisingly, KO did not show deficits aggression. also determined that lacking other AR, ARβ showed normal levels Blocking ARs pharmacologically confirmed neither AR is necessary females. clear attacks. Thus, A. there appears sexual dimorphism control
