I build a theoretical model of an optimal predator and prey interaction. The predator allocates its hunting time among different landscape patches containing prey. Simultaneously, at a much smaller spatial scale, the prey allocate their time between different habitats within each patch. I obtain the Nash equilibrium strategy of each species. When applied to the experimental set-up of little egrets and goldfish in the system of Vijayan et al. (2018, EER 19: 455–468), the model makes four specific predictions available for testing.

Keywords: predator–prey behavioural games at two spatial scales, predation risk, foraging opportunity,
optimal foraging of both species, predicted influences of food abundance.
