Overview
Provide at least 680 litres with open swimming room, live rock for grazing and water at 22 to 26 C. It settles well and feeds readily on spirulina, marine algae, sponge-based angelfish preparations and frozen mysis, though corals and clam mantles may be nipped. Keep only one, as two scribbled angels will squabble.
In the wild
Scribbled angelfish live on coastal reefs across northern Australia, from Shark Bay in the west around to Moreton Bay in Queensland, and along southern New Guinea. They stay fairly shallow, usually between 5 and 20 meters, over rock and coral with rich sponge growth. Most fish are seen alone or in loose pairs.
Good to know
Chaetodontoplus duboulayi grows to about 28 cm and was described by Albert Guenther in 1867. It is one of the few marine angelfish that can be sexed on sight, since males carry wavy blue lines along the flanks where females show spots instead. The fine blue scrawl over the dark body gives the species its common name.
Did you know
Male and female scribbled angelfish wear different patterns, which is unusual among marine angelfish and makes wild pairs easy to pick out.
