🥚 Reproduction
Pelagic spawner. Females migrate to spawning sites, larger females travel long distances to downcurrent areas than smaller ones to protect the eggs from becoming prey to larger reef fishes . Spawning sites are chosen by the females irregardless of the males occupying them . Females spawn in more than one spawning site, each site occupied by more than one male, which are either territorial or non-territorial . After spawning, they return individually to their home ranges without passing through other spawning sites . Some females on the other hand change sex after spawning . As males, they begin to establish territories in the spawning sites, even to those they visited before the sex change . This observation support the suggestion (Warner's 1985, 1986) that females stored information on spawning sites by migrating to various sites which aided in the acquisition of a mating territory after changing sex .
