Behavioral responses to novel situations often vary and can belong to a suite of correlated behaviors. Characteristic behaviors of different personality types (e.g. stress coping styles) are generally consistent across contexts and time. Here, we compare the repeatability and reliability of exploratory behaviors between zebrafish strains selectively bred to display contrasting behavioral responses to stressors that represent the proactive-reactive axis. Specifically, we measure exploratory behavior of individual fish in an open field test over five weeks. We quantified the stationary time, average swimming speed and time spent by a fish in the center area. We found a number of strain differences for each behavioral measure. Stationary time was the most repeatable and reliable measure for assessing proactive-reactive behavioral differences. Reactive zebrafish generally showed the highest reliability and repeatability of exploratory behavior compared to proactive zebrafish and a separate wild caught strain. Given the increased interest in the evolutionary consequences and proximate mechanisms of consistent individual differences, it will be important to continue to investigate how different selective pressures may influence expression of stress coping styles and their effects on the consistency of an animal’s behavior.

There has recently been huge growth in studies of social learning and culture (see Glossary) across 33 diverse species [1,2] successful individuals or copying the majority: [13,25]), much less attention has been devoted to 49 documenting and explaining individual variation in these phenomena within species, or among 50 groups of individuals (e.g. populations) within species. 51 52In experiments, typically the demonstration of social learning, or a particular mechanism or strategy 53 of social learning, in enough individuals or on enough trials to reach statistical significance leads to 54 the claim that this phenomenon is present in this particular species. The authors of one recent study 55

“…Animals use aggression to protect themselves and their offspring, fight for resources and establish dominance hierarchies. Zebrafish aggression has a heritability estimate of 0.36 [41] suggesting that environmental influences play an important role in the expression of this behaviour. Aggression can be measured by recording the interaction of a pair of fish or of a single fish with its own mirror image [42,43,44].…”
