- We investigated whether guppies, a small freshwater fish, occupy consistent positions in social networks. We manipulated the pool habitat of guppies by increasing or decreasing the surface area and found that guppies maintained individual-level differences in the time spent being social and in social preferences across variable environmental conditions. We then indicate the ecological and evolutionary consequences of this phenomenon using simulations.
