Dascyllus marginatus, the marginate dascyllus or Red Sea dascyllus, is a damselfish endemic to the Western Indian Ocean. [2] It is a site attached fish that lives in corals, usually Stylophora pistillata and species of Acropora. In these corals it hides at a moment of danger [3] and sleeps at night. [4] It feeds on zooplankton that drifts with the current, [5] and grows to a size of 6 cm in length. [2] Dascyllus marginatus lives in groups of 2-25 individuals, [6] and while foraging for food around their home coral, group members keep separated and stable foraging spaces. [7]
