Captive breeding / propagation

The offspring of Chaetodontoplus duboulayi are possible. Unfortunately, the number of offspring is not large enough to cover the demand of the trade. If you are interested in Chaetodontoplus duboulayi, please ask your dealer for offspring. If you already own Chaetodontoplus duboulayi, try breeding yourself. This will help to improve the availability of offspring in the trade and to conserve natural stocks.


(Günther, 1867)

Chaetodontoplus duboulayi also known as Scribbled angelfish is a centerpiece addition for any fish-only aquarium. They are distributed from northern Australia and parts of Indonesia southward to Lord Howe Island. Reported too from southern Taiwan waters but very rare.

The Scribbled Angelfish males differ morphologically from the females. The males will usually have clearly defined horizontal dark blue 'scribbled' stripes down their sides and are longer in body, where the females will usually have more a randomized dark blue pattern on their sides and will usually be shorter in body length. Most Scribbled Angelfish start life as females and will undergo the change to male coloration when they reach roughly 10-15 cm in size.

The diet of the Scribbled Angelfish should consist of meaty marine foods such as shrimp, mysis shrimp, clam, scallop, squid, and silversides. Scribbled Angelfish being predominately plankton eaters as juveniles. An underfed adult may attempt to try something new and find that clams and corals are it's newest favorite diet.

Relatively hardy and easy to keep, the Scribbled Angelfish needs a larger aquarium with many hiding places and live rock for grazing and should not be kept with aggressive tankmates. Chaetodontoplus duboulayi is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles. It may be shy at first and should not be placed with aggressive tank mates as already been written. Once acclimated, however, it may become more aggressive.

Most large angelfish are well known for nipping at large-polyped stony corals and some soft corals as well as tridacnid clam mantles.

Husbandry know-how of owners

Ich habe meinen Duboulayi vor 1 Jahr erstanden.
Für 250EUR nicht gerade ein Schnäppchen.
Er frist viel großen Krill, Artemia, Mysis, Frost-, Trocken- und Flockenfutter.
Ist gegen "Pünktchen" nicht übermäßig anfällig,
sollte aber abwechslungs- und vitaminreich gefüttert werden.
Sollte er nicht gut im Futter stehen, kann es auch schonmal vorkommen, das er nach Putzergarnelen (Lysmata amboinensis) oder kl. Neongrundeln (Gobiosoma evelynae) schnappt.
Ansonsten läßt er sich gerne von beiden Tieren putzen...
Mein Exemplar geht nicht an Korallen, versucht aber gelegentlich an Keniabäumchen zuknabbern, was ihm jedoch nie wirklich gelingt.
Verträgt sich gut mit anderen Kaiser- und Doktorfischen,
obwohl er Neulingen gerne zeigt, das er der Chef im Becken ist.
