Nearby interactions and other behaviors under control diet (CD) or ketone ester–supplemented diet (KE) feeding. A Duration of nearby interactions (s). After 5 weeks, the duration of nearby interactions increased in KE-treated surface fish and cavefish. The linear mixed-effect model followed by post hoc Holm’s correction was applied for the statistical tests. B Number of nearby interaction events. The number of nearby interactions was promoted in KE-treated cavefish. The generalized linear model (family = Poisson) followed by post hoc Holm’s correction was applied for the statistical tests. C Swimming distance. KE-treated cavefish exhibited a slight but significant decrease in swimming distance compared to CD-treated cavefish in a 5-min assay. The linear mixed-effect model followed by post hoc Holm’s correction was applied for the statistical tests. D Turning bias ratio. No significant difference was detected between the CD and KE groups. The generalized linear model (family = Gamma) followed by post hoc Holm’s correction was applied for the statistical tests. Data are presented as the mean ± standard error of the mean. Dots indicate individual data. N = 20 for all groups. *: P < 0.05, **: P < 0.01, ***: P < 0.001. All detailed statistical data are available in Additional file 3
