The White-tailed Preußenfisch ( Dascyllus carneus ) is a kind from the family of damselfish (Pomacentridae). The fish live in the coral reefs of the tropical Indian Ocean from the coast of East Africa to the Andaman Sea and the Seribu Islands in the Indonesian Java Sea . There they replace the closely related Red Sea Prussian fish ( Dascyllus marginatus ).

They differ from the Red Sea Prussian fish by their white tail. The fins and a vertical band behind the gill cover are dark. They have 17 to 19 scales along the lateral line organ . The number of gill trap processes is 23 to 27.
Fin formula : Dorsal XII / 14–16, Anale II / 13–14, Pectorale 17–19.
Way of life
The fish live in small groups in coral reefs at depths of five to 40 meters in close association with branch-shaped, cover-giving hard corals . White-tailed Prussian fish feed on zooplankton . They are substrate spawners and maintain and guard their clutch until the larvae hatch.
