  • Dascyllus aruanus off Guam

Habitat

Associated with coral reefs, most usually in groups above Acropora coral heads. Males may be aggressive against other fish while they tend eggs.[2]

Distribution

Whitetail dascyllus is widespread throughout the tropical waters of the Indo-Pacific region, Red Sea included.[1][3] However, the species has recently been split with D. aruanus found in the Pacific and Forsskål's 1775 name Dascyllus abudafur being resurrected for the Red Sea and Indian Ocean populations.[4]

In aquaculture

They are called aquarium 'Starter fish' as they are quite tolerant of variable conditions and aid in conditioning the tank environment for less hardy fish. These fish have been reared in captivity. They can be territorial with other fish. The adult is quite aggressive.[5]
