Asymmetries in the expected value of food do not predict the outcome of contests between convict cichlids
Article Abstract:
Fights between convict cichlids over food reveal that animals larger in size and resourceful usually win contests, though their results cannot be predicted. The aggressive behavior in convict cichlids depends on value expectation asymmetries and hunger. The resource holding potential, the state of hunger and the reproductive condition of the individual also play an important role in deciding contests.

Interactions between patch size and predation risk affect competitive aggression and size variation in juvenile convict cichlids
Article Abstract:
The predictions that the frequency of aggression, degree of resource monopolization and individual size variation within groups would decrease as patch size and predation risk increased, are tested. It is indicated that the frequency of aggression and size variation within groups decreased and the number of fish feeding at any particular time increased as patch size increased.

Heads up: Juvenile convict cichlids switch to threat-sensitive foraging tactics based on chemosensory information
Article Abstract:
A study was conducted to examine whether juvenile convict cichlids, Archocentrus nigrofasciatus, rely on ambient chemosensory information to make threat-sensitive foraging decisions. The results show that juvenile cichlids are able to adjust their foraging patterns in a threat-sensitive fashion in response to ambient chemosensory information.
