A PAINTED robot fish with a smiley face became an instant celebrity when placed in a tank containing living versions of itself. Scientists found their creation attracted both male and female zebrafish which were drawn by movements of its mechanically operated tail.

The 15cm-long robot was spray-painted with blue zebrafish stripes, and given a “smile”. Researchers hope more advanced robot fish will in future contribute to conservation and the control of pest species.
