Behavioral alterations induced by prolonged chronic unpredictable stress (PCUS) exposure and fluoxetine, EPA, or LPS treatment in adult zebrafish tested in the shoaling test (ST; inter-fish distance) and conditioned place avoidance (CPA, time spent in the light compartment). Data are presented as median and Q1, Q3 (total number of still images: 198–541 per group for ST (calculated as distances between each zebrafish in each captured still image, thus representing the number of images taken), n = 12–22 per group for CPA). *p < 0.05, **p < 0.01, ***p < 0.001 vs. control, post-hoc Dunn’s test for significant Kruskal–Wallis data. Graphs were constructed using the ggplot2 R package³⁰, also see Table 2 and Supplementary Table S1 for statistical details). Groups: C control, S PCUS, I intact (no learning), F fluoxetine, E eicosapentaenoic acid (EPA), L lipopolysaccharide (LPS).
