Multiple cues produced by a robotic fish modulate aggressive behaviour in Siamese fighting fishes

Abstract The use of robotics to establish social interactions between animals and robots, represents an elegant and innovative method to investigate animal behaviour. However, robots are still underused to investigate high complex and flexible behaviours, such as aggression. Here, Betta splendens wa...
