Pomacentridae are able to make different sounds
Synchronous underwater audio–video recordings and a passive acoustic detector were used to study the behaviour of Dascyllus flavicaudus. These damselfish produced sounds during six different behaviours.
(1) The sound associated with the signal jump consisted of a male rising in the water column and then rapidly swimming down while making a pulsed sound. This behaviour was initiated when female(s) entered the male territory or in response to signal jumps made by other males. The male territory spread from 50 cm to about 1 m around nests usually situated at the base of a coral colony.
(2) The visiting sound is produced by males when females visit the nests. In this case, males and females perform a pseudo-spawning behaviour during visiting, with both passing over the nesting surface.
(3) The conspecific chase consisted of a simple pursuit and was made when males chased other D. flavicaudus away from their territory area.
(4) The heterospecific chase corresponded to the pursuit of fishes of another species. This was
(6) The behaviour of heterospecific fighting was comparable to that displayed during conspecifics fighting. It was observed only in some Acanthuridae eating algae on the coral colonies next to the nests. No submission behaviour was observed, and no sound was detected in the Acanthuridae.
