The research team examined the shooting behaviour and elements of its significance as a foraging ability in the dwarf gourami (Trichogaster lalius), a common ornamental species adopted as a pet in home aquaria around the world. Dr Nick Jones, of the School of Biology at the University of St Andrews, said: "Together the results provide evidence that gourami shooting has a foraging function analogous to that of archerfish. Gourami shooting may serve as an example of convergent evolution and provide opportunities for comparative studies into the, yet unexplored, ecology and evolution of shooting in fish species."
