Percent of time zebrafish spent near the compressed (“fat”) images side, the unaltered images side, or the center of the tank. Mean ± S.E.M. are shown (n=10). Random chance (33%) is indicated by the horizontal line. Significant deviation from random chance is indicated by asterisks (*p < 0.05, **p<0.01, ***p<0.001). Note that although the percent of time spent near the unalaterd side appears larger, zebrafish showed neither significant preference for nor avoidance of either image side.
