Tracking of individual fish in a group of five fish show impaired social cohesion in KO fish. a–d Movement of a group of five fish was analyzed after video tracking. The position of individual fish during short periods of 1.5 s at two different time windows (5 and 10 min, respectively) was traced, and their path was presented in different colors (#1 fish in red, #2 fish in green, and so on). Aggregation of WT fish group in a corner of tank is apparent (a, c), compared to independent free swimming of individual KO fish (b, d)
