The group has also been called Anthiidae or Anthiinae, but these names are preoccupied by a subfamily of ground beetles in the family Carabidae erected by Bonelli in 1813.
They form complex social structures based on the number of males and females and also their position on the reef itself, and are mainly zooplankton feeders.
Within the swarm of females, territorial males perform acrobatic U-swim displays and vigorously defend an area of the reef and its associated harem.
This may lead to squabbling between the next-largest male, which sees an opportunity to advance, and the largest female, whose hormones are surging with testosterone.
[tone] Seven genera of anthias are known to occur in coral reef ecosystems: Holanthias, Luzonichthys, Nemanthias, Plectranthias, Pseudanthias, Rabaulichthys, and Serranocirrhitus.
