Figure 1.

Plots showing the proportion of time that fish were out of cover during the first trial (T1) and the second trial (T2), highlighting the difference in boldness expression for fish that were housed (a, d) solitarily, (b, e) socially until the first test trial but solitarily until the second trial (partial solitary) and (c, f) socially throughout. Both (a, b, c) scatterplots and (d, e, f) line plots are presented to illustrate differences in rank order consistency, repeatability and temporal changes in risk-taking behaviour. In the line plots, grey lines depict individual responses, black lines depict group average responses, and vertical black bars depict standard errors.
