Adult behavior of hrh1^+/+ and hrh1^−/− zebrafish. a Total distances moved in an open-field tank in 15 min in total by adult hrh1^+/+ and hrh1^−/− fish. b Duration of hrh1^+/+ and hrh1^−/− fish in the border zone. N = 10. c Total distances moved in the novel tank in 6 min in total. N (hrh1^+/+) = 13, N (hrh1^−/−) = 10. d Representative tracking map of novel tank for hrh1^+/+ and hrh1^−/− adult zebrafish. e Statistics of cumulative durations in the bottom zone for hrh1^+/+ and hrh1^−/− adult zebrafish. f–g Statistics of the distances between subjects and cumulative duration in proximity for hrh1^+/+ and hrh1^−/− adult zebrafish. N = 20. Mean ± SEM, unpaired t test, two tailed. *0.01 < P ≤ 0.05; no stars mean no significant differences
