Results of multivariate analyses showed highly significant effects of flow [Pillai’s V = 0.579; F(3,255) = 116.9, P<0.0001] and of speed [Pillai’s V = 0.367; F(12,771) = 8.95, P<0.0001].

The main effect of treatment did not reach statistical significance (P = 0.164), suggesting that gentamicin did not disrupt swimming overall.
In contrast, untreated tadpoles tested in the dark showed a strong trend towards positive rheotaxis ( Fig 4A ).
Rheotaxis approached significance at slower flow speeds.
