Asterropteryx semipunctatus , a small Indo‐Pacific gobiid fish, shows reduced movement and increased bobbing behaviour in response to water that has contained injured conspecifics. This response is qualitatively similar to its response to water that has contained a predator, the lizardfish Synodus variegatus , or to visual contact with a predator. This alarm reaction does not occur in response to water that has contained uninjured A. semipunctatus , injured mollies, Poecilia mexicana , or injured Gnatholepis anjerensis , a sympatric goby. G. anjerensis does not show an alarm response to chemical stimuli from injured conspecifics or from injured A. semipunctatus.
