The affiliation for the ninth author is incorrect. Clément Sire is not affiliated with #4 but with #3: Laboratoire de Physique Théorique, CNRS, Université de Toulouse III – Paul Sabatier Toulouse, France.

In the legend of Figure S1 Video, the unit of speed is incorrectly indicated as m/s. The correct unit should be cm/s. Please view the correct S1 Video below.

Supporting information

S1 Video. Comparison of a fish’s behavior in the presence of a virtual fish and then a virtual ball under control conditions.

Video excerpts of an experiment with a real fish interacting with the anamorphic projection of a virtual conspecific during 30 minutes and then with a non-social control stimulus consisting of a black sphere during the next 30 minutes in the experimental bowl of radius 250 mm. Both the virtual fish and virtual sphere move along a uniform circular trajectory with a constant speed of 10 m/s, at a constant depth of 5 cm below the water surface, and at a constant distance of 10.4 cm to the edge of the tank. The video shows, after one minute, the replacement of the three-dimensional fish model with the spherical model. Top-Left: user interface allowing the real-time visualization of the trajectories of the real and virtual fish (in the xy- and xz-planes) and the instantaneous modification of the parameters of the model driving the virtual fish. Bottom-Left: real-time 3D tracking of the real fish. Right panel: anamorphic rendering of the virtual fish projected onto the acrylic bowl by the rendering application according to the 3D position of the real fish.
