Who follows whom? Shoaling preferences and social learning of foraging information in guppies
Article Abstract:
Learned information is transmitted through fish populations in a nonrandom or directed manner and shoaling preferences may be a strong factor in the social transmission of novel foraging information or feeding preferences. These were indicated by results of an investigation of factors influencing the preferences of guppies for different shoals to clarify how information transmission occurs, given the evidence that shoaling can improve foraging success. Discrimination between shoal partners based on shoal size, size of shoaling fish, foraging experience and familiarity of shoaling fish was noted.

Species discrimination in guppies: learned responses to visual cues
Article Abstract:
Species discrimination in guppies, Poecilia reticulata, depends on general visual cues and mechanosensory stimuli produced by other conspecific or heterospecific individuals within detectable range. The guppies reared with swordtails are visually attracted to familiar and unfamiliar swordtails. This attraction is overridden when other cues for discrimination are present at a close range. They integrate their responses to distance-dependent visual cues to enable recognition of individuals, kin members or species.

Avoidance learning and aggression in guppies
Article Abstract:
An experiment exploring avoidance learning and agression in guppies, Poecilia reticulata, was conducted using 15 male guppies. Results indicate that competence in avoidance learning has a positive relation to time spent in aggressive behavior. Avoidance learning was accomplished by subjecting the guppies to electric shock. The reinforcement schedule was three days, 50 trials per day with a ten minute inter-trial hiatus.
