ToulouseEach rummy-nose tetra followed only one neighbour at a time.
Schools may coordinate without any fish tracking the whole group.
Guy Theraulaz’s team projected 4 virtual tetras around 1 real fish in a bowl, with a camera feeding its movements back.
“By focusing on just one neighbour, the fish reduce their sensory and cognitive demand,” said Theraulaz, University of Toulouse.
Next, the team will make virtual fish act predator-stressed and watch the real tetra respond.
