The Dascyllus marginatus ( Dascyllus marginatus ) is a kind from the family of damselfish (Pomacentridae). The fish live in the Red Sea , the Gulf of Oman in the northwest Indian Ocean, and possibly the coastal regions in between. They replace the closely related Net Prussian fish ( Dascyllus reticulatus ) from the rest of the Indo-Pacific .

Their basic color is whitish to light blue, the outer areas of the dorsal, ventral and anal fins are blackish. The area around the pectoral fins is dark. Their scales are yellowish or outlined a little darker and give the fish a light net pattern. They have 18 to 20 scales along the lateral line organ . The number of gill trap processes is 26 to 30.
- Fin formula : dorsal XII / 14–15, anal II / 13–14, pectoral 18–20.
Way of life
The fish live at depths of one to 15 meters in coral reefs associated with the hard coral genera Acropora , Porites and Stylophora . They feed on zooplankton , small bottom-dwelling invertebrates, and algae. Like all damselfish they are oviparous and care for their brood.
