Betta splendens By Ryan Neale, acknowledgments to Andrew Craig Abstract In investigating the agonistic behavior of the Siamese fighting fish, properly known as Betta splendens , we observed male to male B. splendens agonistic behavior, male to female behavior, and we observed the male’s agonistic behavior towards his own reflection. Our hypothesis entailed that the male B.Splendens would exhibit prolonged aggressive behavior towards other males, including flaring of gills and broadside displays. Male to female behavior would be more docile and submissive in nature. We also predicted that self-recognition would be non-existent in that our subject B. splendens would exhibit aggressive behavior towards his reflection. As hypothesized, our subject B. splendens displayed aggressive behavior when confronted with a male of the same species, not ending its gill flaring towards the male in any of our three trials. Broadside displays also occurred for approximately thirty seconds in each of our ninety second trials accompanied by rapid swimming. Male to female behavior proved more docile, with broadside displays occurring but no flaring of the gills or the rapid swimming characteristic of the aggressive behavior towards the male. The subject also exhibited the same aggressive behavior towards his own reflection as towards the live male of the species. Future work will possibly entail the observation B. splendens agonistic directed towards a dead B. splendens
