The gathering of cells or animals into large groups provides one of nature’s most spectac- ular examples of self-organising behaviour. To achieve this within a fluid environment, though, could involve confronting strong and turbulent flows. Cells and animals can neutralise flows by swimming upstream, a phenomenon termed rheotaxis. But is it always advantageous to use rheotaxis? We look at the effects of flow both in the presence and absence of rheotaxis, teasing out scenarios under which group formation and maintenance is enhanced. Optimised behaviour results not when rheotaxis is always on, but modulated according to local population density.
