Abstract
In Part 1, the preferences of adult male and female H. burtoni, which either grew up only with conspecifics, or only with members of a foreign species Cichlasoma nigrofasciatum, for visual and chemical sexual cues produced by each species, were tested and compared. A double-choice apparatus was designed, in which each single test fish could be presented simultaneously with either visual cues alone of .male.male. and .female.female. of each species, or chemical cues alone of .male.male. and .female.female. of each species. To test the stability over time of the learned preferences shown by the test fish in Part 1, the fish which had grown up with C. nigrofasciatum were put together with conspecifics. At the same time, the test fish which had grown up with conspecifics were put together with C. nigrofasciatum, each individually. Six months later, all animals were tested again in a double choice apparatus, and their responses were compared with one another and with their previous responses in Part 1.
