Acute net stress of young adult zebrafish (<i>Danio rerio</i>) is not sufficient to increase anxiety-like behavior and whole-body cortisol.

Exploratory behavior Young adult zebrafish exposed to an acute net stressor spent less time in the light zone in the light/dark preference test and entered the light zone fewer times compared to control fish ( Table 2 ); however, these differences did not reach statistical significance ( t (17) = − 0.471, p = 0.644 and t (17) = − 0.852, p = 0.406, respectively).
