Fish types did not differ significantly in aggression or freeze behaviour, but triploid brown trout spent a smaller proportion of time swimming passively away from the mirror than rainbow trout (t = 2.48, df = 66, p < 0.05) and almost significantly more than the diploid brown trout (t = 2.26, df = 66, p = 0.068) (Fig. 4 B–D).
