Kommt nur bei Queensland und nördl. Australien vor.
Sehr geringe Verbreitung im Handel ! Juvenile Tiere ähneln dem Chelmon rostratus sehr, haben aber eine deutlich kürzere Schnauze.
Adulte Fische erkennt man hingegen leicht, da sie den hinteren Teil des Körpers komplett eingefärbt haben.
Aquaristisch können wir über die Haltung keine Angaben machen.

Mueller's Butterflyfish is a bit easier to maintain and get to eat than the Copperband (C. rostratus). Above normal but not hard. Maybe it should be rated at 2.5 This fish likes corals and especially Aiptasia.
Feeding and foods: A stubborn fish to sometimes start eating, but I culture Aiptasia in my refugium for just such 'customers.' Offering young Aiptasia dropped from the surface teaches this fish that it CAN eat in captivity AND that 'manna' comes from above. After this introduction, most of mine I can get to eat finely chopped scallop and opened clams on the half-shell. Then soak these foods in vitamins and slip in other fare now and then.
It is shy and peaceful but once eating, it isn't bashful at feeding time! The fish is not a panicky kind of fish. But using a dither fish in quarantine, will help calm it down.
As always the aquarist will have an easier time acclimating this fish to the captive environment by first putting it through quarantine where the fish can learn to feed (and can be inspected to be sure it is disease-free), and relax.
The fish is not often offered in North America, but now and then they come in, in fairly great numbers. Choose a healthy specimen of about 3" (7.8 cm) and make sure its nose/mouth is not injured, otherwise it will never start to eat.
