Non-social behaviors for the heterogeneous shoals in experiment 2.

<p>(<b>a</b>) Distance from bottom was not significantly different between groups. (<b>b</b>) Distance from center was significantly lower for the heterogeneous MK-801 group. (<b>c</b>) The heterogeneous MK-801 group spent more time in quadrants 2 and 3 than the control group. (<b>d</b>) Travel distance was not significantly increased for the heterogeneous MK-801 group. White bars represent the control group (i.e. quadruplets consisting of four zebrafish treated pre-exposed to water), black bars represents the heterogeneous MK-801 group (i.e. quadruplets consisting of three zebrafish pre-exposed to water and one zebrafish pre-exposed to 5 µM MK-801). Means ± SEMs are shown. Significant differences between heterogeneous MK-801 and control groups: ***p<0.001. For control group, n = 18; for heterogeneous MK-801 group, n = 18.
