Anthias

Fish - Marine

Anthias are mostly small, peaceful, and beautiful; and are thus quite popular within the ornamental fish trade. 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. They occur in all tropical oceans and seas of the world. The first species recognized in this group was described in the Mediterranean and northeast Atlantic and was given name Anthias anthias by Carolus Linnaeus in 1758.
