Figure 3.

Adult behavioral assay responses. Individual fish were introduced into a custom box with a side view of an LCD video monitor, and their acclimation to a novel environment (novel tank) was measured for the first 10 min, followed by (A) predator response (response to video of a predator) and (B) schooling (response to video of another zebrafish). For both, the first 60 s of the measurement period is the “acclimation phase” (not shown here), followed by 60 s of the “video” phase. **p < 0.01; ****p < 0.00001; ns, not significant. (C) Startle response (response to a total of five taps).
