Dascyllus marginatus (marginate dascyllus or Red Sea dascyllus) is a damselfish endemic to the Western Indian Ocean.[1] 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[2] and sleeps at night.[3] It feeds on zooplankton that drifts with the current,[4] and grows to a size of 6 cm in length.[1]Dascyllus marginatus lives in groups of 2-25 individuals,[5] and while foraging for food around their home coral, group members keep separated and stable foraging spaces.[6]
