Description

Interspecies aggression is used by many organisms as a way to win mates, gain food resources, protect offspring, and develop status within social groups. In this study, we assessed the level of conspecific aggressive behavior observed before and after feeding in male and female Sunburst Wag Platies (Xiphophorous maculatus). We hypothesized that when feeding bloodworms, a high value food, to two fish in the same tank, conspecifics will show more aggressive behavior and be more territorial after the addition of the food compared to prior to the feeding event in an effort to protect their food source. We used different sex pairings, (two males, two females, and a male and female together) to get a better understanding of how sex combinations impact aggression levels in response to food territoriality, and hypothesized that males will show more aggressive behavior than females. We found that aggressive behaviors do increase after the addition of a food source, and that one individual was more dominant compared to the other. This resulted in the dominant individual usually consuming more food than the subordinate, however; they were both able to consume the majority of the food without any aggression when the food density was high.
