Life Cycle
provided by Fishbase
Male selects and protects the nest; does the courtship `dance' about 1 m above the nest and escorts the attracted female to the nest site where spawning ensues (Ref. 33146). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Also Ref. 103751.

Trophic Strategy
provided by Fishbase
Occurs inshore (Ref. 75154). Territorial, inhabits shallow lagoon and subtidal reef flats. Forms large aggregations above staghorn Acropora thickets or in smaller groups above isolated coral heads. Feeds on plants and invertebrates (Ref. 6110). Harem-type social structure observed with 1 male & several females with linear size dependent rank order; male spawned with the females in order of rank & may attempt to male with females from nearby territories. Male & largest female protect the home territory. It is associated with coral heads (usually Acropora or Pocillopora) that have a tree-like form, allowing the fish to retreat deep within the branches. Humbug lives only where the coral heads are interspersed with sandy patches, usually in protected lagoons or sheltered bays, only occasionally on outer slopes (Ref. 54301). Diurnal species (Ref. 54980, 120737).

Biology
provided by Fishbase
Territorial, inhabit shallow lagoon and subtidal reef flats. Form large aggregations above staghorn Acropora thickets or in smaller groups above isolated coral heads. Feed on zooplankton, benthic invertebrates, and algae. Males invite females to spawn in their nests; protecting the eggs until they hatch and becoming very aggressive against other fish. Eggs hatch after 3-5 days; pelagic larvae feed on plankton (Ref. 5503). Oviparous, distinct pairing during breeding (Ref. 205). Used in behavioral study. Have been reared in captivity (Ref. 35412). Diurnal species (Ref. 54980, 120737).

體呈圓形而側扁，標準體長為體高之1.5-1.7倍。吻短而鈍圓。口中型；兩頜齒小而呈圓錐狀，靠外緣之齒列漸大且齒端背側有不規則之絨毛帶。眶前骨具鱗，眶下骨具鱗，下緣具鋸齒；前鰓蓋骨後緣多少呈鋸齒。體被櫛鱗；側線之有孔鱗片15-19個。鰓耙數23-24。背鰭單一，軟條部不延長而呈角形，硬棘XII，軟條11-13；臀鰭硬棘II，軟條11-13；胸鰭鰭條17-19；尾鰭叉形，上下葉末端略呈圓形。體呈白色，體側具
3條黑色橫帶；在吻部與眶間骨間的頭背部上具一個大的褐色斑點；唇暗色或白色的；尾鰭灰白；腹鰭黑色；胸鰭透明。
棲地
provided by The Fish Database of Taiwan
主要棲息於潟湖內的淺灘及亞潮帶的礁石平臺水域。通常會在鹿角珊瑚叢的上方形成大群魚群或者在孤立的珊瑚頂部上面形成較小群魚群。具強烈的領域性。以浮游動物、底棲的無脊椎動物和藻類為食。生殖期時，雄魚會邀請雌魚產卵於他們的巢中，並保護卵直到它們孵化，而此時的親魚變成對其他的魚非常有侵略性。卵約在
3-5
天之後孵化；仔魚行大洋性漂浮生活，以浮游生物為食。
Whitetail dascyllus
provided by wikipedia EN
Dascyllus aruanus, known commonly as the whitetail dascyllus or humbug damselfish among other vernacular names, is a species of marine fish in the family Pomacentridae.[1]
Description
Whitetail dascyllus is up to 10 centimetres (3.9 in) in length but its common size is 6 centimetres (2.4 in) and is white with three black vertical bars.[2]
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]
