The effects of an increase in group size on the location of a concealed food resource by stone‐loach were examined. Food was located more rapidly when group size was increased from one to five individuals. This was achieved by a reduction in the time taken to start searching for food, and by a reduction of travel time. We also found, at group sizes of two and five fish, consistent differences in individual foraging abilities, which were correlated with each fish's patch location performance when alone.
