[en] The concept of Acoustic Niche plasticity refers to the plasticity of acoustic resources allocation within a species. Few studies have focused on this adaptability in fish species. The relationship between anemones and clownfish is one of the best-known symbioses in coral reefs. However, other fishes also use anemones for shelter. The three-spot damselfish (Dascyllus trimaculatus) may inhabit the same sea anemone as the orange-fin clownfish (Amphiprion chrysopterus). Because both Pomacentridae species communicate acoustically through the same sound production mechanism, their sounds are very similar. We have demonstrated that D. trimaculatus produces shorter sounds when it shares its anemone with the clownfish. In addition, the daily sound production cycle of D. trimaculatus changes in the presence of the clownfish. It decreases sound production during the day and produces more sounds at sunset. These modifications should reduce the acoustic overlap of the signals produced by both species and differentiate the acoustic niche of D. trimaculatus from that of A. chrysopterus, thereby minimizing competition. This study supports the concept of Acoustic Niche plasticity and reflects the ability of the three-spot damselfish to adapt its sound production according to the presence of another vocal species (Amphiprion chrysopterus).
