Dascyllus

Dascyllus melanurus

Bleeker, 1854

Fourstripe Dascyllus, Blacktailed Dascyllus

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Sumatra to Vanuatu, east to Caroline Islands, north to Southern Japan, and south to New Caledonia.

Size: 3 inches (8 cm)

Natural Environment: Inhabits shallow lagoons, back reefs, reef faces and fore-reef slopes at depths between 3 to about 30 feet (1 – 10 m) and mainly feeds on planktonic crustaceans (copepods, mysis, and shrimp larvae), fish eggs and filamentous algae.

General Husbandry: Fairly common in the trade, yet not a peaceful community fish. Both juveniles and adults have a white body with four black vertical bands, the first through the eyes, next two on the mid body, and the fourth on the tail.

Best housed with dottybacks, large angelfishes and surgeonfishes, and triggerfishes.

As to diet, a meaty diet, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam and plant material, e.g., flake foods, especially those containing Spirulina should be offered several times daily.

Taxonomy:

    Order: Perciformes

    Suborder: Labroidei

    Family: Pomacentridae

    Subfamily: Chrominae

    Genus: Dascyllus

FYI: Juveniles can be maintained in small groups, yet as they age, will quarrel with each other, and tankmates even if they are also quite feisty.

Cute when small, but devils when they mature. Think twice before putting these in your aquarium!

Expansive growths of branching stony corals provide this species a more appropriate environment.
