The dascyllus melanurus ( Dascyllus melanurus ) is a kind from the family of damselfish (Pomacentridae). The fish live in lagoons and coastal coral reefs in the central tropical Indo-Pacific , from Sumatra to New Britain, the Solomon Islands to Vanuatu , north over the Philippines to the Ryūkyū Islands , near Yap , Palau and Pohnpei and south to the Great Barrier Reef and New Caledonia , at depths of one to ten meters. Recently there is also evidence of a population in Tonga .
The fish live in small schools mostly in isolated branched Acropora sticks outside the actual reef. They feed on zooplankton , including copepods , shellfish , amphipods , larvae of larger crustaceans, and fish spawn.

Aquaristics
Four-banded Prussian fish were popular ornamental fish in saltwater aquariums and are also suitable for beginners. Because of the import of more colored fish and their tendency to aggressive behavior, they are no longer imported as often. However, they are considered less aggressive than other Prussian fish. The animals are territorial in the aquarium . With good care, they spawn in the aquarium.
